Pass or Spectral

I have a Pass XP-20 and XA100.5 which sound great together and in my system. I have heard Spectral gear, though not the top of the line like you mention, in a system that had the same tt as mine but different speakers and room, so I can't really compare. That SME/Spectral/MIT/Magico system was the best I've heard. At this level, you have to match the electronics to the speakers and your taste. I have not heard the Focals. The dealer should let you audition these electronics in your system before committing, but I'm pretty sure the same dealer doesn't represent both of these top brands.

Drjoe brings up a good point about the Spectral gear needing very expensive MIT cables to sound their best. The Pass is slightly warmer with very natural timbre and glorious midrange, while I found the Spectral ultra clean and detailed. They are both great.

I just got a used Pass x1 here and it really sounds wonderful. I agree about the warmer sound, but still towards neutral. I would expect the XP 10 and 20 would be a significant upgrade. The build quality is so nice of their equipment and you can get a human when you call with a question. Haven't needed service but Pass always gets great props from those who have.

I am using Focals with a Pass XA.5 amp, and I can tell you that I love the combination. My system is considerably more modest than yours, but hopefully that helps a little.

completely different sound. think if you like one, you would hate the other.

I agree with the above posts that Spectral equipment requires expensive MIT cables. If you decide on Spectral, you need to include MIT cables for the best sound and performance. In my opinion, the Pass will sound warmer, be more natural and has a great midrange. The Spectral is great sounding with MIT cables and is very detailed. The build quality and customer service on both units are excellent. Both Pass and Spectral are expensive so I suggest you listen to both using your speakers before you make a decision.
