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.

 @bluethinker thanks for posting about the I-50. I owned a VSI-55 about 15 years ago and was wondering about the I-50. Does anyone know what's been done to "upgrade" this amp to the newest addition? 

I found the VSI a little cool, perhaps the Op did too if he's moved on.

 

I don't see an impedance curve on the Pure Audio site. Anyone that claims high efficiency in my mind should post such information. Instead they say "effortless and dynamic sonic performances with any amplification." That's usually misleading an expensive for people to find, but maybe I missed this information.

 

Keep us posted good thread.

I am running an http://www.triodelab.com/ 2A3EVO amp and really love it, my speakers are 97db efficient which is equivalent to PAP Trio. The mid range is magical and it has a nice quick/tight bass. I don't listen loud. I have had it for 2 years and it is the first amp I have had where I have no desire to change, yet....

I was trading emails with Ze'ev (PAP owner) and he said he uses a 2A3 Set amp as part of voicing the speaker.

I am considering the same speaker with the horn when finances allow.

Good Luck

The necessity to have a dealer or technician bias tubes in the Audio Research I-50 is a large negative to some of us.

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?!
