Passlabs X2.5 + X150 + SF Grand Piano Home?

My friend using Blue Circle Pre amp, X250 to drive his SF EA MK2.

Sound is good.

More power is ok. I find that it's better for the speaker.
Its only the RMS power that's we are looking into. Usually, speaker don't need much of this power to drive them.

I think the above match is o.k. But u might want to consider a pre tube amp to make the sound warmer. There is lot of good reviews on the X150. This amp is class A/AB.

Try to audit them first.

FWIW, about 2 years ago I was driving Quad 988 (86dB) with the Pass 2.5/150 (I assume you meant 2.5 not 2.3) combo and was quite pleased. The 988 impedance drops to 2 ohms around 10Khz if I'm not mistaken and the 150 didn't miss a beat. I believe your speakers are 90dB with a 6 ohm impedance. You should have plenty of power for your SFGP. Pass sounds more musical and engaging than Bryston, Krell, and Classe' IMO but to each his own.
Good luck.

thanks for all the replies.

I'm very sensitive to bright sound, will the combination give me bright sound?

unfortunately there is no way to pair them with the SF home before buying.

Many Thanks.
