    Hi,

    I am after some recommendations for a stereo amp to use with Amphion Argon 3S speakers. I realise these are not common speakers on these forums... The amp needs to have a HT bypass to be used in conjunction with a Marantz SR7010 AV amp. I would prefer second hand option to look out for. I am keeping an eye out for a Hegel H200 or similar, but any other recommendations would be appreciated.

    ^ I thought that was a pain to turn av mode on/off?

    Musical Fidelity M3i sounds nice and has a HT bypass input for the AVR.

    Had considered a PM8005 or even pearl lite. MF3.5 has also been considered, M3i I don't know of, I'll check it. Thanks.

    Roksan Kandy K3. Has the AV bypass and will sonically destroy the Marantz

    Once up into Roksan K3 price range, then Yamaha A-S1100 become worth a look as well (also with AV bypass and 12v trigger driven auto-AV input selection for seamless use with AVR).

    There are quite a few of here with either the A-S1100 or A-S2100 amps using them either as hifi amps or as hifi+av amps and very happy with them.

    Amphion Argon 3S Bookshelf Speakers - $1350 EACH -

    Hegel H200 Integrated Amp - est retail US$4500 - 150w/ch -

    Hegel H200 Amplifier review and test

    There are several ways a Stereo Amp can be integrated into a Home AV system -

    1.) Parallel - run two independent systems in parallel (AV & Stereo) with a Switch so they can share the Front Speakers.

    2.) Series - and by that I mean, use the Pre-Amp out of the AV Receiver to drive a secondary Amp for just the Front Speakers. This could be an Integrated amps, or more likely a pure Power Amp.

    In this case you would always be using the Pre-Amp in the AV Receiver.

    3.) Series Alternate/Parallel Alternate -
    A Stereo Integrated amp can be connected to the Pre-Amp outs of the AVR. All video related sources are connected to the AVR, and all Stereo related sources are connected to the Stereo.

    The problem with this is, you need to remember to turn the Stereo volume down before you play music as it is likely to be very a loud to accommodate the AVR Pre-Amp. Equally, when changing from Stereo back to AVR, you have to be able to set the volume into a known and fixed position for use with the AVR. Not that hard, just remember the display reading, if the Amp has a Display, or if a position related volume control, put a thin piece of tape on the Amp Face to mark the position the volume needs to be in to consistently work with the AVR.

    For simplicity sake, I would be inclined to simply get a power amp, preferably Class-AB, of a price and quality consistent with your need, and attach that to the Pre-Amp out, and using Pre-Amp section of the AVR will all your sources - digital and analog. With any of these combinations, there is going to be some down side, you just have to work out what down side best accommodates you.

    The Marantz SR7010 is a considerable AVR, and should have a good Pre-Amp section -

    Marantz UK | SR7010

    I think these were selling for about £1100 new, though it is hard to be sure.

    Also, consider upgrading your AVR.

    Marantz UK | SR8012

    Marantz SR8012

    And others to consider -

    Arcam AVR550 7.1.4 Channel (Dolby Atmos) AV Receiver

    Arcam AV860 AV Processor

    Also -

    Yamaha RX-A3080 Aventage 9.2 Channel AV Receiver

    Denon AVC-X8500H

    And -

    https://www.hifix.co.uk/home-cinema...cinema-amplifiers/anthem-mrx1120-av-amplifier

    And more -

    https://www.hifigear.co.uk/rotel-rap1580.html

    Once you cross a certain threshold in AV Receivers, there is no down side. Even if they are using Class-D amps, they still sound stellar.

    If you really want to get serious, you will move to a Pre-Amp/Processor and a Series of Power Amps. Though count on this costing some serious money.

    https://www.hifix.co.uk/home-cinema/home-cinema-separates/multi-channel-power-amps

    Should I win the lottery and be able to afford my fantasy AV system, I would get a good AV Processor, perhaps a Marantz AV8805, then add a 250w/ch Parasound Stereo Power Amp to driver the Front Left/Right. Then add another 250w/ch Parasound 3-Channel Power Amp to driver the Center and Surrounds. If you want 7.1, simply substitute the Center/Side/Rear with a 5-channel Class-D (or Class-AB if you prefer) Power Amp. Trust me though, that is a pile, a big pile of money.

    Home Cinema Pre-Amp/Processors -

    https://www.hifix.co.uk/home-cinema...pre-amps/arcam-fmj-av860-av-pre-amp-processor

    Cutting the cost back a bit, one could get a good Rotel Class-AB, 200w/ch Stereo amp, the fill the remaining channels with a Rotel 5-channel Class-D amp.

    Rotel RB-1582 MkII Stereo Power Amp, 200w/ch, Class-AB - £1200 -

    https://www.hifix.co.uk/hi-fi/hi-fi...o-power-amps/rotel-rb1582-power-amplifier-mk2

    Rotel RMB-1585 5-Channel Power Amp, 200w/ch, Class-AB - £2500 -


    https://soundcrafthifi.com/rotel-rmb-1585/

    There are other amps to consider, for the moment I'm just illustrating the possibilities.

    Is that of any help?

    These are super highly regarded amplifiers with first class dacs too and tons of current. They’ll drive just about anything very well indeed.

    It was a statement product from Harman Kardon, and as such was about the best they could do.

    Which is very good.

    The 990 also has two sub outs, four digital inputs and room correction too.

    I’d snatch it up instantly if I were you.

    You won’t do better for less than eye popping, testicle shrivelling money.
