Seeking opinions about Pass Labs 250.5 amp.

Ok, that's interesting. Very well then. However, the higher capacitance and bigger transformer results in more stability. The XA30.5 uses small caps and transformers. Yes, of course you do that.

Ok, I have this question; is the X350.5 much better or just a bit better than the X250.5. I do see that the X350.5 uses much bigger caps and has a bigger transformer than the X250.5. So I would think that it would be more transparent and dynamic.

Ok, thanks, much appreciated. I thought that would be the case regarding the difference in sound between the X250.5 and the X350.5. Thanks for confirming it. Now have you owned the X350.5, or are you saying you wish to own it? As for the rest, I'm not a big believer in aftermarket power cables, but I could certainly try it, I suppose.

Ok, have you heard the X350.5? I hear you regarding cables. I do believe in quality interconnects and speaker cable, and I use them, but not really power cables or power conditioners.

I agree with you about the business, and being just in it for the money is always a bad thing.

Well, that makes sense that the bigger Pass Labs amps will give you those things. It boils down to much more capacitance, bigger transformer (I believe the X350.5 has a 1kVA transformer in there) and better control of the speakers. I did read that the smaller XA amps are a bit on the slow side and have loose bass. So, it seems that the X series is the better choice if you want speed, tight bass, and detail. As you said, you get 40 watts of Class A from the X350.5, so that's great. That's cool you have listened to the X350.5. What were your impressions?
