Pass labs XA60.5 anything wrong with them.

Thanks for your response.

I rarely see Pass Labs amps for sale, and I would so like to experience them, given all the raves.

But seeing 3-4 being offered for sale made me think that maybe these are underpowered (or too entry level at $11000!) and people move on to higher powered amps. Though I think for me 60W is more than plenty.

I am finally on the path of moving off from my Jolida 801A, if I pull the trigger this might be a super big jump.

I had them for some time. I also owned the XA-100.5 and 30.5. To be honnest for the money the 30.5 and 100.5 were better. These amps I used with the XP-20 Now I use the X250.5, overwhole sound I prefer a lot more over the XA60.5. The slamm and speed in the low freq are better. it is still a very warm and musical amp. It is a little bit more open than the XA60.5 The XA100.5 were a lot better than the XA60.5. The difference between the XA30.5 and XA60.5 is smaller.

Thanks for highlighting the differences. So do you prefer the Class AB amp to the Class A amps? I always feel that Class A sounds better, and even Pass Labs says as much.

I thought I prefered the XA over the X series. I am not sure anymore. It has to do that I use the Purist Audio LE 2013 powercable. This gives me a much higher level out of the X250.5. I think I will go for the X600.5 later this year. There is a big difference in speed and slamm. Maybe the XA series are more warm sounding. Purist Audio powercables open up the mid freq a lot. Maybe this is the reason why I do not want to sound it more warm. I love the speed in the low freq. With both you cannot go wrong. One thing I know 100% sure, The next amp will be a Pass.

"Now I use the X250.5, overwhole sound I prefer a lot more over the XA60.5."

This is a very system (and listening preferences) dependent statement. For example, I auditioned the XA30.5 vs. the X250.5 on Thiel 2.4s. The X250.5 had some midrange harshness that made it slightly grating on the Thiel's and made the vocals (even Kanye West's) less natural. The XA30.5 has much more natural sweetness and a better soundstage (with those great vocals), but is somewhat weak in the bass. I think this is an issue with the XA series in general, which makes people think they don't have enough power, and draws them up the line (hence the XA60.5s becoming available). I personally love the XA amp so much (even though it's underpowered for my speakers) that I just dealt with the bass issue by adding a Thiel sub. I also know someone else who was looking into speakers with powered bass units for the same reason. In any case, the Pass amps are awesome, and the impression I've formed is that if you want great bass, you should go with the X.5 series, but if you want great soundstaging and vocals, you should go with the XA series. Also, just fyi, both of these amps just killed a McIntosh MC-402 which another Thiel 2.4 owner had loved.
