    I believe that Yamaha have new Amps/recievers coming out in july in the UK .normally in the yam ranges the only difference between the reciever models RXVand the amp modelsDSP is the tuner
    In the states the new models are out in april all have pro logicIIx and they have uppped the power also the 750 has the Yamaha self calibrating system as on the RXV1400

    here is a link to a japanese press release
    http://www.yamaha.co.jp/news/2004/04021801.html

    if you run it through babelfish
    http://world.altavista.com/

    it comes out in english (well not quite but enough to get the jist of things)

    heres some more info from USA

    badly translated from japenese< DSP-AX750/DSP-AX450 main merit >


    1. It throws the Yamaha individual technology which is established reputation, actualizing the treble quality which is optimum to all sources
    Speaker driving force is raised with the low impedance conversion which all circuit is thorough "high current amplifier technology"(Note 1)with, signal route of the AV amplifier which is complicated is reed-construct to high purity and straight "digital maximum concept"(Note 2). The music of CD, furthermore until DVD audio and SACD, the treble quality which you can have enough in ƒnƒCƒNƒIƒŠƒeƒB was actualized from the movie of DVD with the Yamaha individual treble quality technology which is established reputation. Furthermore digital/the pure direct mode which plays back the 2ch audio source of analog in a higher purity (Note 3), you adopt also the treblequality 7ch corresponding intelligent digital volume due to YAC520 and YAC523 of the Yamaha original device for DSP-AX750.


    2. Various setting adjustments are automated "YPAO (BASIC version)" (DSP-AX750)
    In DSP-AX750, when the foam/home theater such as the number and size of speakers which are connected and distance from viewing position constructing, by the fact that the setting adjustment which is necessary is automated, YPAO which can obtain the playback environment which is simply optimum even with new one*(BASIC version) it loaded. Operation being simple, installs the microphone of attachment in the listening point, just starts the YPAO menu presence of the speaker, speaker size, volume difference of the speaker, automatically measuring 4 items in range difference of the speaker it optimizes.

    * YPAO (Yamaha Parametric ROOM Acoustic Optimizer)


    3. The audio delay function which adjusts the timing of image and sound
    At the time of large picture playback the lines which become matter of concern (sound) with it cancels the delicate gap of image, the audio delay which adjusts the timing of both (the lip sink) equipping function. From flagship model DSP-Z9 to DSP-AX450, function of the advancement which it is essential to large picture playback age of plasma TV and the projector etc. was adopted, the ƒtƒ‹ƒTƒCƒYƒ‚ƒfƒ‹ all type of Yamaha DSP AVamplifier*.

    * RX-SL100 (the slim component) you exclude


    4. "Cinema DSP" of Yamaha originality is included, loading abundant ƒTƒ‰ƒEƒ“ƒhƒvƒƒOƒ‰ƒ€ of 31 types
    Real it exceeds also the cinema sound field origination technology of the Yamaha originality which reproduces the appearance impression, cinema DSP(Note 4)it depends, adjusting to the work including "CONCERT HALL" and "MOVIE THEATER", loading abundant ƒTƒ‰ƒEƒ“ƒhƒvƒƒOƒ‰ƒ€ of 31 types which it can choose. Yamaha original 32 bit floating point arithmetic processing LSI 2 and YSS-948 (for decoding) with YSS-930 (for sound field processing) due to with the high accuracy processing, the appearance impression of the cinema DSP which is established reputation it improved more. Furthermore DTS 96/24, it corresponds to also Dolby professional logic IIx anew, it has made the full format complete correspondence design which can play back the up-to-date contents widely.


    5. In discrete playback of 6.1ch ƒfƒWƒ^ƒ‹ƒTƒ‰ƒEƒ“ƒh complete correspondence
    In DSP-AX750 the 7ch power amplifier and the 6.1ch decoder, in addition the 6ch power amplifier and the 6.1ch decoder are loaded in DSP-AX450, focusing on the up-to-date movie the discrete of Dolby digital EX and 6.1ch ƒfƒWƒ^ƒ‹ƒTƒ‰ƒEƒ“ƒh of DTS-ES where adoption increases (all the channel independence) in playback correspondence(Note 5). 6.1ch the DVD software and the like which was recorded is played back while it is the original appearance impression. Without ƒTƒ‰ƒEƒ“ƒhƒoƒbƒNƒXƒs[ƒJ[ it equips also the phantom playback mode which can do 6.1ch playback.


    6. The amplifier assign function which connects up to total 9 speakers, it selects automatically the 7.1ch playback system of 2 types according to ƒTƒ‰ƒEƒ“ƒhƒvƒƒOƒ‰ƒ€ (DSP-AX750)
    With DSP-AX750 which builds in the treble quality 7ch power amplifier for 7.1ch playback, the Yamaha individual cinema DSP sound field effect can be actualized at the highest level, the presence (front effect) speaker left and right are included, the "7.1ch cinema DSP effect" and, "the 7.1ch playback which uses ƒTƒ‰ƒEƒ“ƒhƒoƒbƒNƒXƒs[ƒJ[*" it is corresponding to in each case. At the time of 7.1ch playing back, up to presence speaker and total 9 speakers which include ƒTƒ‰ƒEƒ“ƒhƒoƒbƒNƒXƒs[ƒJ[ connection*it is possible, selecting the optimum speaker which is adjusted to ƒTƒ‰ƒEƒ“ƒhƒvƒƒOƒ‰ƒ€ automatically, it makes that it plays back possible.

    * ƒTƒ‰ƒEƒ“ƒhƒoƒbƒNƒXƒs[ƒJ[ corresponds to left and right independence drive.
    * * It cannot sound ƒTƒ‰ƒEƒ“ƒhƒoƒbƒNƒXƒs[ƒJ[ and the presence speaker simultaneously.


    7. It can enjoy to also nighttime theater admiration of force, "knight listening mode" "silent theater functional" loading
    With the environment where a sound leak to around such as nighttime becomes matter of concern, popular "knight listening mode" was improved by the fact that it can enjoy comfortable foam/home theater admiration without the appearance impression and impairing force, optional feature of the movie/the music was adopted anew. While guaranteeing the appearance impression and the articulation of lines even in a state where volume is squeezed, in combination with a sound leak of sudden large volume and the sub woofer zone which are easy to become neighboring annoyance, to the source it prevents this function, effectively. In addition, it can enjoy the appearance impression of 5.1ch with the stock headphone, it loads also "silent theater function" collectively.


    8. 2 system of wide band D4 input terminal, rise converting & down converting correspondence
    Function of completeness such as video conversion circuit
    Component D4 of the 720p correspondence which utilizes the efficiency of high picture quality image equipment such as hi-vision TV and progressive DVD player(Note 6)2 system, and S image input 5 system of the image input terminal (3 systems) and the like equipping DSP-AX450 the input/output terminal of the completeness which is included. Furthermore, component D <- S <- -> the composite (as for DSP-AX450 S <- -> the composite, as for the component D signal only through input/output) each image signal loaded also the rise converting & down converting & correspondingmutuallyit can monitor can output video conversion circuit, improved the using selfishness of the AV amplifier largely. Furthermore, also each type actualizes the economical electrical design below waiting electrical 0.1W.

    * The conversion to S or composite output (down converting) it is not possible from component input.

    Note 1 "High current amplifier technology"
    Inside high current amplifier technology promotes the low impedance conversion which because accurate speaker drive is actualized strongly the power amplifier, the speaker terminal, and all circuit where it reaches to the ground point are thorough from power source, makes ideal of the amplifier it is the new design philosophy which aims toward impedance "0". After removing the rise primary factor of internal impedance the various low impedance design parts (low impedance design power transformer, custom specification large-sized block Chemical Condenser, the pole thickly due to) adoption such as jumper pin and copper ground point part, in order for transmission loss to become smallest, it takes a second look also construction fundamentally.


    Note 2 "Digital maximum concept"
    As for digital maximum concept, it is something which actualizes the treble quality due to the minimization of analog signal route to the power amplifier with the improvement of the digital section. Until recently, as the bus management which has done in the analog territory (low channel distribution of the limits component) the analog filter circuit is removed by the fact that it processes digitally in advanced 32bitDSP "YSS-930" inside, by the fact that the Yamaha make high accuracy volume element which has the variable gain plus side is adopted, residual noise is held down, the level adjustment circuit of the pre-amp circuit and each channel to channel is removed, minimization of analog signal route is actualized. Furthermore, the 192kHz/24bit specification advanced DA converter is adopted for all channel and high accuracy D/A conversion is actualized.


    Note 3 "Pure direct mode"
    It is the mode which you can enjoy from the 2ch audio source which begins CD with treble quality. The decoder and sound field processing DSP the bypass are done at the time of digital signal inputting, minimizing noise source e.g., FL of stop and display of the video circuit is done darkening (going out). Furthermore from you can enjoy music playback with more treble quality by minimizing signal route.

    * Only digital PCM input and analog input correspondence


    Note 4 "Cinema DSP"
    Monaural, from the 2ch stereo to up-to-date 6.1ch, the Yamaha individual sound field origination technology which reproduces the existing all audio format in the optimum appearance impression. It can solve the difference of acoustic quality of the cinema and the concert hole and general home, it seems that quite experiences the story of the movie, it seems that in addition is in the concert hall, it can have enough the reality which does not have peer.


    Note 5 "6.1ch playback"
    As for 6.1ch ƒfƒWƒ^ƒ‹ƒTƒ‰ƒEƒ“ƒh, with the digital movie audio format which adds the ƒTƒ‰ƒEƒ“ƒhƒoƒbƒN dedicated channel to former 5.1ch system, focusing on the up-to-date movie adoption is advanced. Presently 2 types "of DTS-ES" and "Dolby digital EX" have spread as one for home, you use the power amplifier and the speaker of all the channel amounts to which each of them includes one for ƒTƒ‰ƒEƒ“ƒhƒoƒbƒN, with the system which plays back the 6.1ch ƒfƒWƒ^ƒ‹ƒTƒ‰ƒEƒ“ƒh signal which is recorded to DVD and the like, you can obtain the faithful appearance impression and force with the sound design of the movie.


    Note 6 "D4 terminal"
    High picture quality it transmits the image signal as the independent signal of Y/Pb/Pr, it is the connected terminal for the component signal. D1 - There is the standard to D5, as for D1 usual television broadcasting and DVD (480i), as for D2 progressive broadcast and progressive DVD (480p) is, but HDTV (generally known digital hi-vision) the fact that it corresponds is D3 and D4. As for D3 as for 1080i and D4 it corresponds to the transmission to 720p. D5 is 1080p of the highest picture quality, but presently there is no product with only standard.

    BUENA PARK, CA -- Yamaha Electronics, an industry leader in home theater products, has introduced four new digital home theater receivers that enhance the overall home theater experience at a variety of reasonable price points, beginning as low as $299 MRSP. The RX-V750 and RX-V650 include an essential new feature called YPAO (Yamaha Parametric Room Acoustic Optimizer), which was previously available only in higher-end receivers and is a technology that completely simplifies the home theater set-up process. YPAO automatically analyzes room acoustics, then sets parameters for optimum sound quality at the listening position at the touch of a button.

    The 7.1 channel RX-V750 and RX-V650 and the 6.1 channel RX-V540 and RX-V440 receivers all feature Cinema DSP, Dolby Pro Logic IIx, Dolby Digital-EX, DTS-ES Discrete 6, DTS-ES Matrix 6.1 and DTS neo:6. All models have high-current discrete amplification for the highest quality sound reproduction, plus a new, easy-to-use setup menu with 5-band center channel EQ, speaker distance adjustment and night listening modes.

    The RX-V750, with a suggested retail price of $599, is a highly sophisticated 7.1 channel A/V receiver that features Dolby Pro Logic IIx, Dolby Digital-EX, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS neo:6, Digital ToP-ART, an on-screen display and a preset remote control with an LCD display.

    Dolby Pro Logic IIx is the first and only technology to process any native stereo or 5.1 signal into a 6.1- or 7.1-channel output, creating a seamless, natural surround soundfield that immerses you in the entertainment experience. With Dolby Pro Logic IIx, users can choose Movie or Music modes to tailor their listening experience to source material, including an exclusive Game mode that delivers full-impact special effects signals panned to the surrounds.

    With its enhanced directional steering, DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1 offer six fully independent channels of sound with an extra rear center speaker that has its own separate effects, providing unparalleled quality sound from a receiver in this category.

    In addition, DTS Neo 6 provides 5.1-channel surround processing from any stereo source--even from two-channel CDs, tapes, VHS and LPs__--and delivers full-bandwidth stereo surround channels.

    Yamaha's Digital ToP-ART technology maximizes digital quality while minimizing analog circuitry by bringing together several key elements to create the best-sounding, user friendly A/V components available. These elements include high-current discrete amplification, Linear Dampening Factor for the left and right channels, and low-impedance drive with discrete circuitry to all channels. Also offered are Zone 2 audio out capabilities with an I/R port, extended I/R codes and pre-outs for all channels. Zone 2 has the ability to drive a set of stereo speakers in another room using an external power amplifier.

    Rated at 100W x 7 high discrete power (20Hz-20 kHz), the receiver is able to deliver sophisticated DSP processing enabled by the YSS-948, a 32-bit Floating-Point LSI that yields 29 DSP programs with 53 possible variations.

    Cinema DSP provides an audio experience that sounds better than most theaters. Cinema DSP is designed to bring out the full potential of movie sound formats, reproducing them the way directors and sound engineers intended for them to be heard. And, for listening to late-night multi-channel presentations in privacy, it uses Silent Cinema, which provides a 5.1 channel listening experience using a pair of ordinary two-channel headphones.

    Other features include eight-channel analog inputs for external decoders to accommodate high-resolution audio formats like DVD-Audio, SACD (or other future formats); four optical and two coaxial input terminals; one optical output terminal; front-panel A/V inputs with a digital input; two component video inputs and one out put for HDTV 720p/1080i compatibility; five total video inputs and two outputs; S-video connections for all inputs and outputs; and a phono input. The receiver does component video-up conversion from composite to S-video, to provide high-quality picture from all video components connected to the receiver for optimal viewing. In addition, the 96 kHz/24-bit digital-to-analog converters are used for all six channels.

    Next in the series is the RX-V650 discrete 95W x 7 A/V receiver (20Hz-20kHz), which replaces the RX-V640 and is priced at $499. This new model has all of the features of the RX-V750 except for the LCD remote control, phono input connection and an aluminum front panel.
