I currently have a 2525h and a 2555x and am comparing them.

I have them both running through an amp switcher into a Suhr reactive load so that I can really just hear the differences between the amps.

They both have the Jubilee sound but they are a bit different. I will do my best to describe.

The best overall summary is the 2555x is exactly what you would expect, the 2525h is really close in sound but leans a bit more into a plexi's dynamic feel. It feels like you get into power amp interaction/compression more easily on the 2525h (starting at about 2 o'clock) while the 2555x stays really clear only sagging a bit when maxed.

2555x. the feel is tighter/harder. It is less saggy. And less dynamic. It doesn't pick up nuance in your playing as well - it is like it is committed to sounding like itself and is less interested in how you sound. It sounds dead on like you would expect. It has a bit more treble and a bit less low mid. It is a little more hollow sounding. Bass frequencies seem identical. It is a very clean and clear sound - nothing leaking out anywhere.

2525h. The feel is a bit looser and more squishy - this is not drastic compared to the 2555x, and would be hard to hear but is also quite evident under the fingers. It captures you picking and finger expression. It feels more like it is conveying subtleties. It is ever so slightly less self controlled.

With both amps may favorite sounds were with the master at 2-3 o'clock, lead at about noon, gain experimenting between 9 and noon. EQs mostly flat, a bit less treble and presence on the 2555x. I also tried many other variants like lead knob maxed (a la slash). The mid knob range is more enjoyable to me on the 2525h.

With the clean channel the 2525h is a bit more full. The 2555x is more thin.

I could not get the 2555x to feel like the 2525h - the closest was maxing the master volume, but it wouldn't really get there and had too much gain. I could get the 2525h to sound very close to the 2555x by just bringing the master down to about 1-2 o'clock and cranking the lead master.

I play mostly with lower gain, and after this experiment, really love the 2525h. It is super expressive. It is definitely my preference.

If I was absolutely committed to nailing the classic Jubilee sound I would go with he 2555x. Especially with rhythm parts. Like when playing GnR, Mr Brownston, My Michelle, it just sounds perfect. I'd say it is a bit more contained and clear with higher gain.

But the 2525h also seem to nail "that sound", until you compare them side by side, and then you realize it's like 2% off.

Hope this is helpful

Had you not included your description in such a way, I’d think you were off your rocker or never played a SLP in your life. However, the details expressed in your explanation make sense to me (as one who has owned a 2550 and a 1959, but never played a 2525).

Interesting that you find the 100 watt brighter and cleaner. Makes sense.

The 50 watt sounds a bit different from either then. My 50 watt Jubilee is darker and less "airy" compared to my 2525H.

If you want to get the 2525H to lean a bit more Studio Vintage put in KT66 or 6CA7. I agree about the dynamics of the 2525

I guess you did this comparison in a room context.
In a band context, I find 2555x very dynamic and responsive to the pick attack and finger expression.
2525h would be more appropriate for the studio environment (as the name says) while 2555x is a live monster.

Right - the comparison was to get the amps to their sweet spots and compare at the same listening volume.

I've also played them both with band, but it's impossible to compare in this setting since the 2555x is louder and has to reach higher dbs to get power amp saturation I'd say the 2525h is better for smaller rooms and the 2555x is better for bigger rooms. Obviously LOL. I haven't played the 2555x in an audience setting yet, because I haven't had the chance to play in front of a crowd big enough to absorb that type of assault lately - Indeed a monster.

This is of course assuming you aren't going through PA/monitoring, because if you are, then they will perform just like they would through the Suhr Reactive Load. This was all about how the amp sounds directly before environment, and without their different volume capacities.

Trying the KT66s does sound like a nice idea =)
