Pass INT-25, split decision and maybe option?

There have been some great suggestions and the cables are definitely worth looking at.  I was also in a similar situation with my very expensive SS integrated which I really enjoyed but slowly realized I missed the tube sound.  Purchased a nice tube integrated and listening with a smile on my face!

Someone mentioned modwright and they're a brand I would definitely look at. Their KWH225i is a hybrid integrated. I have a pre of theirs and love it. Tthe Music Room is an authorized dealer and they often have an open box for a great deal. Might be a good match

Looks like the consensus is try a tube integrated. :-) I was hoping that the INT-25 would bridge the gap between solid state and tubes, but I think that was hoping for too much.

I'll look for a good tube integrated. I've had Audio Research in the past, so that's definitely an option

I definitely like the options having a Pass Preamp with the Sit-4…maybe it’s me but having separates is really nice…the Sit-4 really sounds nice with my horn speakers. I had a lot of tube gear in the past with lots of problems with the Primaluna gear. I always missed tubes so just yesterday I put in the Modwright Analog Bridge and it definitely changed the tone for the better, I slammed all the most harsh sounding fingers on a chalkboard electronic music through it and wow it took enough of that harshness away so I didn’t leave the room..one song I love is from Duran Duran Ordinary World it took that song and gave it a nice sweet tone..

I also have the XA-25, love the Sit-4 more…if you have to go all tubes play it safe and get the Cary Audio SLP-80…

To @audiojan its not that we believe your INT-25 could not work, but we all have been in a situation where the sound was too much in one way or another and lacking in other areas compared to our "last" system setup, for example. Then we find ourselves fine tuning in other areas upstream, like changing DACs or (sure enough) trying different cables again etc. It’s kind of a balancing act to get there.

I had a pair of these popular [other brand] OCC cables once that were so open, transparent, huge sound stage, and simply were not as engaging, and for my taste they were a bad match for one of my amplifier setups. Went back to simple pure copper ICs and speaker cables I had before. All the sudden things settled down, quite a bit actually. The midrange music was back again. Two other buddies had the same cables, same issue, all of us resold them. It happens some times with different setups. Some cables I've tried can cause situations like this too, fwiw.  

A few last thoughts, free to try fwiw:

• Warmup: As a quick test, can you leave your INT-25 powered on for 48hrs, particularly so if it’s been sitting cold in a box somewhere and before you received it? No joke, I had recently rotated my older Pass/Forte’ amp back in recently and it had been out of rotation for six (6) months. First try was not smooth, grainy, too etched. Left it on for a few days, went back and listed again, and a very nice change on the first startup back into the system. Better every time since. That’s one things to try.
• Toe-in: Are your PAPs toed in quite a bit now? Can you try to toe them back out almost straight forward for a bit, listen for a while, see how it goes, then slightly toe-in again if needed at all, or none.
• Cables: do you have a local shop you can borrow any other less open/airy ICs going between your main device/DAC etc to your INT-25?

Best of luck, just a few thoughts before you jump ship to a tube integrated. This whole thread has me thinking too what my next consolidation move might be btw.
