New set up for digital music, amp advice
I have bought a new house and have sold my old seperates to pay for a new upgrade. I had a Arcam Alpha 7se Cd Player, Arcam Alpha 8R amp and B&W DM602 S2 standmount speakers. I loved the sound and what to achieve a modern equilvalent. I am finally saying goodbye to my CD collection and am going digital (I know it cant compete sonically but is much more convenient), I am looking at getting a Sonos Connect & Bridge, B&W 685 speakers, a DAC (either dac magic or rDac), but am struggling on an amplifier to go with them. Budget is around £500 but ideally less. The amp must have a remote which rules out the Rotel, I have seen low price Arcam a18 amp in richer sounds but not read good reviews, Im not sure the Marantz PM6004 will be up to the job....advice please!
And here I thought CDs were digital 
I think I will now insist that the proper term is dematerialization 

Hello! I can share my deep, personal experience with you, sir.I went to audition some bookshelf speakers in a small shop, that is very close to what a small room is, nothing was isolated.I have auditioned Mordaunt Short Aviano 2, KEF Q100, some expensive Quadral Argentum 330, JBL ES 30, Tannoy Revolution DC6.Compared to Boston Acoustics A26, all mentioned speakers were nothing short of a joke.When I have read this forum, somebody suggested that the smaller model, A25, is even better in detail and midrange.Boy, was he right...Connected both and compared both models...The A25 has much tighter bass that did not veil or smidge the other part of the sound, and even when playing a bloody 128kbps mp3, it retrieved amazing detail - I finally know that this unknown instrument in the song is actually a harmonica!I have never heard such neutral, open, alive and musical speakers in my life.The B & W are not musical at all.Boomy, bassy, hard to drive...I`d avoid them like the plague.The rDac has a hefty, heavy sound, it is far from neutrla.I connected Arcam rPac to the A25, and I was more than overwhelmed.Take your time and audition the BA A25 - you have to see ( hear ) it to believe it.Marantz PM6004 is a joke, I compared it with a second-hand HK6550, that was much cheaper, and the difference is night and day, even the shop sellers were shocked.Try to find this amp, it easily outclasses even the Roksan Kandy K2 in terms of sound.You do not need to spend much money in your case.
Finally. A well balanced, subtle and non-exaggerated view ...
regards
I have just heard the B&W CM1s which I believe to be uprated 685s, they look good but for me not that engaging or musical although better than the Rega RS1s and were boomy with anything like double bass and probably too bass heavy. You really must demo speakers before buying. As for amp MArantz 6004 I hear is a bit ligtweight for its rating. If I were I you I would probably keep your amp. or look around for an Arcam 9 or 10, I really don't think the amp will make that much difference. I would also consider some active speakers, that have amps and dacs inside them, the AVIs are about £1,250 which seems to be less than you currently plan to spend.
What's with the AVI recommendation? He wants an amp at £500 or less!
NAD is a good option - fine sound, good price, complete with remote. The 326BEE would be my pick.
