    Hi all. :)

    In US forums, I have read quite a lot of positive posts about digital receivers, mainly the Panasonics and Sonys.

    Panasonic models coming out soon:
    http://www.highfidelityreview.com/news/news.asp?newsnumber=18868399

    I'm surprised not to see them mentionned often over here (including the Denon 770).

    Would anyone be willing to share their experience with these supposedly "future of amplification"?

    TIA. ;)

    Some info about the Denon AVR-770SD:

    • 6-channel digital power amp with total output of 600 watts
    - Dolby Virtual Speaker, for dramatic surround in 2 or 2.1 channels • Dolby Headphone for private surround
    • 32-bit floating point Hammerhead SHARC DSP, as used in DENON's £3000.00 high-end AV amps.
    • Auto Decode function detects the format of the incoming signal from the disc being played and selects the most appropriate surround decoder. Multi-channel sources in DTS and Dolby are played back in surround. 2-channel sources can be played in stereo or in multi-channel via Dolby Pro Logic II / DTS Neo:6
    • Video Conversion converts composite to S-Video
    • Comprehensive inputs & outputs inc component video
    • 6ch external input supports SACD & DVD-Audio multi channel sources
    • Banana plug speaker terminals for all channels • 435 (W) x 80 (H) x 380 (D) mm

    Heard saw the new sunfire reciever recently seems very good! tiny package and huge sound! http://www.sunfire.com/receiver.htm
    but heard much about others, ICE power amps seem pretty good though.

    Thanks for the reply, hornydragon. ;)

    The Sunfire has preamp outputs for all channels.
    This would seem to indicate it's not a true digital pre/amp (as I understand it), as there would have to be a digital to analog conversion somewhere.
    Maybe the conversion is only present to feed these outputs, and the path between the pre and amp actually stays in the digital domain.

    I didnt go to see the sunfire range it just happened to be driving the soeakers i was auditioning. The lack of DVi or HDMI makes me think that you are probably right but are you talking of Digital processing, Digital amplification or Digtal signal paths?

    "...are you talking of Digital processing, Digital amplification or Digtal signal paths?"

    All of the above. ;)
    If you use the digital input, the signal stays digital from the source to the speakers.
    In the case of the forthcoming Panasonic receiver and DVD player, multi-channel DVD-Audio is passed through the HDMI lead.

    Some interesting reading:

    I've been following some of the threads on the digital amps. That they supposedly sound this go so early in their life is a good sign but it doesn't look like they're always a magic way to great sound. The Panny needs some tweaking to give it's best apparently and the Harman DPR 1001 gets panned more than it gets praised.

    I was thinking of trying the BK electronics modules or even building a Zap pulse stereo amp. Haven't got the spare cash to waste on experiments at the moment unfortunately. :(

    That Denon looks very interesting and only £350 I wonder how it handles low impedence loads?
