B&W 705 or Sonus Faber Concerto / Concertino

The 705s with a good high current amp is what u need, they are thirsty for power, not wattage, but good electronics also.

The arcam is light in that dept, quality amp/sound but not good for 705s, the only good combo i have heard is the rotel 10series.

I played with the naim 5i, great sound , but 705s do need a kick.

Cant speak for the concerto etc.

Im using a classe 70 with my b&w 705 and they sound really full with deep bass my wife allways ask me to turn it down the less than quarter volume. Im using a melos 110 line stage with telefunken tubes and a 400 volt strapping cap I really enjoy my system. Bring your intergrated and have them hook it up so you can hear what they will sound like with you amp.

Choosing a speaker is a personal thing. That I will leave it to you.

However, I would have to chime in on the amplifier selection. Do yourself a favor by auditioning a Naim Nait 5i or better still Nait XS. These amps sound a lot more musical and involving than the Arcam(to my ears) and match well with both B&W and Sonus Fabers. The Classe matches well with B&W but not with Sonus Fabers .

Are you talking about Domus Concertino/Concreto or the older Home/Concert series? Domus is quite different from the earlier models and I prefer the older models. The old ones are both monitors, whereas the Domus Concerto is a small floorstander. I think the Toys and the Liutos have replaced the Domus line. If you are looking new, you should look at those. If you are looking used and the old line, I would definitely prefer the Concerto to the Concertino, for not much more money. The Cremona Auditors are a real step up and the older ones (non M) are pretty available used, at a higher price, unfortunately.
