    Hi,

    I need a bit of help / advice please. I have a Roksan K3 integrated amp and a matching power amp, which has an A/V bypass feature. Basically my plan - or I am wondering if this is possible - is to buy a suitable A/V amp to link up to my current hi-fi setup to watch films etc. I’ve looked at this one, but it’s physically a bit too big, however I like the array of features onboard.

    Denon AVR-X2500H Black 7.2 Channel AV Receiver - AV Receivers / Amplifiers - AV Online - UK Home Cinema and Hifi Specialists

    I would like to have one subwoofer too. My speakers are Kef R700’s, so bass isn't exactly lacking, but I’d like the extra grunt that a subwoofer brings for movies and Xbox’ing.

    Finally, and I think this might be the tough one - I’d like some active bookshelf speakers to act as rears. I would imagine that finding an amp with all of the features I'm looking for may be a tough ask.

    I predominately listen to music, but I’d like a bit more ‘woompf’ for movies.

    So...what would your recommendations for:

    An A/V amp with my required features?
    A subwoofer - must be gloss white?
    Active bookshelf speakers - must also be white?

    A lot to ask I know. Many thanks in advance. All ideas and advice appreciated.

    To use active speakers you'd need Pre-out connections which means stepping up to the 3500 which does have a full set or pre-amp outputs

    I know the 2500 doesn't have multi channel preouts but I'm not sure if it does have front channel pre outs or not so it might not even be suitable for running to your stereo amps anyway.

    The 2500 doesn't have pre-outs, the first model in the Denon range to have them is the 3500. Even though the R700s have adequate bass you would still need a sub to take advantage of the LFE channel, the .1 channel, for those effects that are dedicated to the .1 domain. Having the sub will also take the load off both the receiver and the Roksan by having all frequencies below 80hz directed to the sub.

    Even though you have the R700s in the set up, for film and TV you would need to run Audyssey and manually set the crossovers of your fronts to 80hz and all speakers as small and not full range.

    Ok, that’s brilliant. Thanks for your replies so far guys. So the 3500 is the front runner so far. Anyone know of a more slimline version with similar features?

    You'd still need an AV receiver that included pre outs. The AVRX2500 hasn't pre outs for the main room's channels apart from those associated with the subwioofer. You'd need an AV receiver that includes pre outs for the front left and right channels. You'd connect these pre outs to the K3 integrated amp.

    You could use a speaker switch and an AVR without pre-outs. Marantz have a couple of slimline AVRs with pre-outs for front left and right channels.

    Magic, thank you. Would I therefore be correct in assuming that this would fit the bill?

    https://petertyson.co.uk/marantz-nr1509-slim-5-2-channel-av-receiver

    Sorry for all the noob questions. I had an original Dolby surround amp (pre even 5.1 or THX) - things have moved on somewhat from then!

    It should be noted that you are sacrificing power in order to fascilitate the slim design of the Marantz BR1509. Even if using external pow amps to drive the front 2 speakers, you'd still be reliant upon the AV receiver's own amplification to drive the other 3 speakers. Slimline receivers are more commonly used in smaller or secondary rooms as opposed to the main listening room due to their lack of power. You get anything from one third to double the power from a similarly priced full sized model.

    If wanting something similar to the AVRX2500 that includes front left and right pre outs then look at the Yamaha RXV685. This is about the same level of receiver as the DEnon and will be as powerful as the DEnon. If wanting a comparable Marantz model then look at the SR5013, but it has to be said that this isn't very good value for money when compared to the Denon AVRX2500 and is basically the same receiver despite you paying a premium for the Marantz name. All Marantz models include pre outs for at least the front left and right channels.

    Note that if still wanting to use active rear surrounds then you'd still need to look at an even more expensive receiver such as the Denon AVRX3500 in order to get thepre outs needed to connect a pair of active rear surrounds to. I'd suggest using more conventional passive surrounds anyway in order to save money which would or could then be better spent on the AV receiver.

    I'm not sure as to whether or not you are aware of 3D immersive formats such as Atmos? Note that you'd be unable to access such formats using just a 5 channel receiver and the 7 channel models so far mentioned all include Atmos and DTS:X decoding. You would however need to add 2 front height, upward firing or downward firing ceiling speakers to your 5.1 setup in order to portray such formats.

    Yes, that is what I had in mind, there are the NR1609 / 1610 and a new 1710 which have a bit more power, but not much. Also they all only have pre-outs for the front left and right speakers so using actives for the rear speakers would not be an option.

    I think the Denon 3500 would be a better investment, it has a lot more features and power and should give you a lot of options for your set up.

    The outgoing 3400 model here looks like good value:

    Denon AVR-X3400H

    As already said this wouldn't allow actives for the surrounds, it does however have front L&R preouts for the stereo amp.

    TBH do you have a particular reason for wanting actives for the surrounds? I can't think of a compelling reason if I'm honest. You'd need long RCA cables which would be bulky and all speakers would need their own power.

    Thank you all for your replies so far. The Denon 3500 sounds great having looked at the specs - thank you for the suggestion!

    Ok...just to clarify a couple of things - the reason for wanting actives for the rears is because there is no facility to run cables to them. The surround system is an addition to my existing hifi and TV in our extension, which has been purpose built to provide disabled facilities for myself when the disease I have progresses. I’ll try to add a picture later on to illustrate what I mean.

    Basically my bed faces the TV (not too surprising!), which is where all of the system is situated and I have sockets in the wall behind me so powering active speakers won’t be problematic. I also have a shelf behind me for them, which I know is far from ideal but it’s what I’ve got. I must say that when we built the extension I had no plans whatsoever for such a comprehensive system (or I would have thought about and allowed for this), but you know how ideas evolve!

    A subwoofer would be an easy addition as it would sit in a corner along the wall where my hifi sits. I also have a socket nearby. I hope this clarifies things a bit.

    For the rears, I was looking at these:

    Edifier 2.0 RMS 88W HiRes Monitor luidspreker Optical Coaxial Bluetooth AptX Stereo RCAen XMOS USB ingang. Remote. Alu. Bas conus (S880DB) https://www.amazon.co.uk/dp/B076HX9S4M/ref=cm_sw_r_cp_tai_gaHbDbGS9H1RV

    Silly question I’m sure - how do wireless active speakers work? Is there some sort of sender unit that fits into the relevant speaker outputs? Am I confused as to what an active speaker is?

    You'd still need to run cables to the active speakers in order to convey the surround audio channels to them. You'd have to run a left and a right RCA terminated coax cable from the AV receiver;s left and right surround pre outs to the speakers.

    If unable to do this then it should be made apparent to you that not all AV receivers have the ability to convey audio associated with the surrounds wirelessly. Your best bet would be one of Yamaha's newer models that can convey audio to their surround speakers wirelessly using MusicCast. MusicCast is proprietary to Yamaha though so the active speakers would need to be a pair of Yamaha's MusicCast 20 speakers or a single Music Cast 50 speaker:

    The cheapest model to both include pre outs for the front left and right channels as well as the ability to use Music Cast speakers as surrounds would be the RXV685.

    Home AV setups do not ordinarily facilitate sending audio to the speakers in the main surround setup via wireless.

    Dante - thank you! That’s exactly what I’m looking for. I do appreciate that my set up isn’t the norm, and it’s not how I’d ever really intend to do it if truth be told, but in my current situation it’s an ideal solution.

    Thank you to everyone who has read and commented on this thread. I accept that I’d got my wires crossed (pun intended!) but I’m happy with what I need now. All that’s left now is to run it past the Household Finance Committee...

    Just a quick update - following all of your advice and suggestions, I will be ordering the Yamaha RXV685 and two Musiccast speakers today.

    Thanks again everyone. I really appreciate your time and knowledge.

    Sorry everyone, I have another question and after searching online I can’t find a definitive answer. I am expecting the delivery of my new AV amp, a Yamaha RXV685 imminently along with the requisite Musiccast speakers.

    My questions are thus:

    I have a Roksan K3 integrated going into a K3 power amp bi-amping the main speakers - how do I connect the AV to the K3?

    Do I set the switch to HT?

    Does having a power amp complicate matters? i.e. will the K3 be able to interpret the AV signal and deal with it correctly?

    Sorry for all the most likely silly questions.

    Connect the Roksan to the AVR by RCA interconnects to the pre-out on the rear of the unit, just left of the sub-woofer connection. The pre-outs are live all the time and therefore there is nothing to set on the Yamaha. The Roksan, I believe has HT by-pass, you would need to engage this when wanting to use the front speakers for films alongside the Yamaha. The volume of the Roksan is then controlled by the Yamaha.

    You need to disconnect the front speakers from the Yamaha and run them from the Roksan.
