Pass INT-25, split decision and maybe option?

I recently bought a used INT-25 to drive my PureAudioProject Trio15Classic. I have never been so torn by an amp as by this one! On one hand the details are addictive, but on the other hand, the details can be so distractive that I struggle to listen to the music. The INT-25 does do space really well and that’s definitely something I love and look for in an amp. I do miss some of the midrange magic and the warmth that a tube amp brings as well.

 

At this point, I’m not sure the INT-25 is going to stay. There’s so many things I love about it, but other things that distracts me from listening to the actual music.

 

I also miss some of the warmth that tubes bring. Is there such a thing as an integrated tube (or hybrid) that retains all the strength of the INT-25, but adds the midrange magic and warmth of the tube amp? Don’t mind if I lose some of the distracting details in the recording, but don’t want to give up too much of that. The PAP's do like a bit of power (the INT-25 is definitely sufficient), so low power SET's are not likely where I'd go.

I may have discovered why this INT-25 is not working well... to get to a volume that’s about conversational, I need to turn the volume up to 50 (the volume goes to 63). I borrowed a new INT-25 from my local dealer (their tech is out, otherwise he could’ve looked at it) and on that unit at about 30 it was quite a bit louder than conversational.

Could it be that I simply struggle with the amp because of a gain issue?!

Certainly, you cannot make any judgements about INT-25 from the faulty unit you first received! Is it possible to retain your dealer’s loaner long enough to make a proper evaluation? Sounds like you have a solid enough relationship to make this happen. It would be a shame to let a (rare) faulty unit dominate your conclusions. Definitely sounds like a gain stage somewhere in the circuit has "crapped out" - maybe passing signal without the appropriate gain.

@audiojan I think you'll get over the distraction.  but it sounds to me like you'll go bak to tubes.  either way, you'll have a good system.

Hi. I recently added a Pass XA-25 amp fed by a Holo Audio Serene preamp. I really do like the clarity and solidity of this combination driving my Klipsch Forte's... Previously I had an Elekit TU-8600S 300B SET amp. The Elekit did some things quite nicely but way too noisy and the bottom end was muddied. I think if you're after tube sound, you can add it higher up in your signal chain.

You could try adding the “Analog Bridge” by Modwright between your source and integrated amp. It will add that tube warmth and midrange back. I love mine and use it between my amp and preamp. I feel the 6SN7 tubes will give you what you want, but you have the option of 6922 tubes as well.
