Pass Labs XA30.8: is it enough for Wilson Sasha 2?

I’d the opportunity to test the integrated amplifier Pass INT-150 in my ‘sound room’, substituting the ARC LS5 + Symphonic Line Kraftwerk.
After some hours of plays, what I can say is that the INT-250’s sound is refined, very clear, with a good dynamic and soundstage. But the old chain remains still winning. The ARC gives to the sound more details to the mid and sweet to the highs. The Kraftwerk after provides more current to loudspeakers and then the sound is more rich, robust. Also bass are more powerful.
I think that I should try a true class A Pass power unit...

I look forward in reading more about your situation- pinox67

Happy Listening!

At the date the best amplification chain that I tried with Sasha 2, but also with B&W Nautilus 803, is with ARC LS5 + Ahifi 845 pair. The latter is an old power unit built by a small Italian builder, based on a pair of 845 tubes, the same mounted on Nagra VPA.
What you have from Ahifi 845 is not so far from VPA: These ones give to sound an incredible sense of spatialy, in all directions, sounds objects are very well defined, sound is sweet, rich or harmonics, solid. Bass are not so strong, but well controlled.
Magic of 845!

I'm surprised by your statement, probably is not the Symphonic Line at fault here but the speakers-room interaction???

Not enough power look at Pass 250.8 or keep on trucking!!!
