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.

Sounds like an amp issue. Did you even control the volume from your dac or via Roon or something is turned way down (DSP)?

The impedance curve is a range, like a set of stairs that the amp had to walk constantly. Nominal doesn’t mean much for a speaker load especially when talking lower powered tube amps.

Volume is set as fixed for the AirLens (and in Roon) and the PS Audio DirectStream is set as fixed, high, 96 (which is max). Everything is at full blast into the amp, yet at almost full output of the INT-25 is barely above conversational level.

1 watt should give you 96db near the speaker so should hardly be conversational at the level you are setting it. Something is off.

  • Typical distance from rear wall: 2-4′ (60-120cm)

Personal rant: The wall behind the speakers is the FRONT WALL. It's the wall in FRONT of the listener but behind the speakers. If this is the back wall then what is the wall behind the listener. the "other" back wall?

 

Just a personal pet peeve, carry on!

I went to a bar in Colorado and the sign read: liquor in the front poker in the rear. Point is we don't want to mess these things up. Well stated Thompson.
