Short List of Amps I prefer over the Pass Labs XA25 or INT 25

The only amp from Yamaha that was any good, and that was for only bass duties was the P2200.

Cheers George

Have any of you compare the pass amp with Bedini 25/25 100/100 ? For 1/3 prices of pass amp , I’m happy with my Bedini , I also have Yamaha as2100 , mx1 and they are not far behind but I prefer Bedini 

Chorus, I recommend that you get your hands on a new or used Sugden A21SE class A signature single ended. I’m using it on my Tannoys and it sounds wonderful. $3250 new....30 watts into 8 ohms, 40 into 4 ohms....no bells, no whistles, just 5 line inputs, a record out, and a remote......my Tannoys are the Legacy Eaton's....

In my opinion, the question posed by the OP and the responses that followed are all presented in the absence of the central question of what speakers will be partnered with the proposed amplifiers. Without this information, most if not all the recommendations boil down to personal preferences.

IMO the First Watt amps are nothing special.  I have heard four of the upgrades so far.  I built a FW amp using better parts and point-to-point wiring that was much better in every area.  Cost me about $500 in parts, etc.

As for Luxman products (which I like BTW) I met the Luxman rep a month ago.  He was trying to tell me that EI transformers were quieter than toroidals.  That goes against anything I ever learned.  He told me after many years of research this was their findings.  So what does that mean?  Well nothing if you prefer the sound of their products.

As for the OP question, the amps that I build are what I prefer but knowing Pass Labs products the one you are referring to is an excellent amp when I had it in my system.

Happy Listening.
