Sonus Faber Grand Piano Home Speakers with a Used Krell KAV-400xi or S550i Integrated Amp

I have had that speakers and kav 400, with Cardas GR speaker cables.
At the time, that was ’bespoken’ combination for an ’entry’ level system, but together with Meridian G 08 cd player.

As for the sound of kav 400 or S 550i, I can only comment on first one, since I have not heard the s550, but, if that may help, I have heard the s300 from that same line of production.

Kav 400 is powerfull, but ’gray’ sounding amp that must be paired with ’rich’ sounding speakers (like yours)

S300 was major disappointment, very much ’closed’ on the top, even when paired with much more expensive source (Burmester 001 cd player) the sensation was like I have blanket over my speakers.

So, between the two, kav 400 is safe (cheaper as well, I would guess) option, since you do not need more power to control those speakers.

As for ’musicality’ or if you have plans to change speakers in future, I would look for some other solutions.

If you choose to stick with that combo, be sure to try some ’rich’ sounding dac

I owned the Grand Piano Concerto (predecessor of the Home) back in the day. Must be more than 20 years ago now. I sold it to someone who owns the Krell KAV-300i and the combination was quite stellar. The speakers sounded more open, live and dynamic with the Krell than the amp I was using at that time,  which I had forgotten since it was a long time ago.

s550i not often appears for sale like s300 or kav400xi,that means it should sound better
