Too Much Gain the Issue ? (preamp and amp)

@mulveling +1 on tube rolling definitely worth exploring

Also, in my experience, rarely anything is a “direct replacement” when it comes to swapping components in the system that’s been tuned over time to have a specific sound. And introducing a different amplifier is not a small change. I won’t be surprised if you might need to work with speaker placement and toe in as well as revisit the cabling.

Preamp tubes are optimized- all spots have early 50’s Sylvania 6SN7 GTA. Smooth as glass.

Tried putting the EH, Ken-Rad and Raytheon in and no help.

I am also experimenting with cables. I have tried everything. The sound is like a slightly scratchy upper midrange that sounds a bit too strong and distinct.

I love the sound of the XA25, it really lives up to the hype.  If I cannot get the 30 to work I will move it on...

OK, that's fair and sorry I doubted you! I have 1950s Sylvania 6SN7GTA in my collection, and can confirm they're smooth. I was hoping you were using EH because that would have given you an easy move in the right direction.

I roll several components in my main rig, and some combinations just don't work great for whatever reasons. Sometimes you can mitigate a bit with tube-rolling, but it's most important to find components that mesh well together. And it's not always JUST the amp & preamp pairing either - upstream (phono / SUT / cartridge) and of course downstream (speakers) are also big players in whether the whole system gels together. 

Buy a very low output MC cartridge to soak up some of your excess gain.

Buy some really inefficient speakers.

Most people would kill for the gain you have.

But the Cary preamp gain is mad high.
