Could use your advice re: tube gear

I posted a long discussion of my MC240 and 8B which came out of storage a couple weeks ago. After listening to them with several speakers in our little local shop, and in comparison to an Anthem 700 MRX SS integrated ($2K) driving the speakers I'm thinking about, I'm missing the highs I thought I was getting. Quite a bit. And on big speakers the bass is loose and very undefined. Both tube amps (with my CJ PV-5) had vastly better midrange though.

What would be a move to keep the mids of my gear but get the defined bass and airy open highs?

Get a SS amp (like the DNA-1)? But would the CJ kill the tight lows and open highs? Could I mod the CJ?

Can I find a (~$1K used) tube amp that has the lush mids but tight lows and open detailed highs? The Quicksilver GLA maybe?

Trying to solve it with speakers, I could probably find a speaker with much tighter bottom (B&W CM-1 maybe) but that would not solve the highs. I have some Superzeros with spiky highs that help but don't replace the missing air and space.

Your thought would be greatly appreciated.

Thanks.

I got the Jolida because I was bored and curious, and I like the sound of it a lot. It holds up really well in comparison to the SS amps I've owned in the sense that it's quiet and has plenty of dynamic juice. I'm really liking the tube "warmth", colorful tonal palette, and the fact that I can mess with it just by changing tubes.

The Jolida 302 and 502s have wonderfully overbuilt power trannies (output is a different story but still very competent. Lots of space for mods. And a simple enough circuit topology to allow the modder to be flexible with tube choices and current draw and make mods without breaking the bank (direct coupled input to driver stage).

Here's my meaningless comment of the day: My mods cost less than my dinner last night. Including drinks.

Jeez. If Jolida's mods cost as much as Underwood's, then you had some good wine indeed.

I searched Jolida's website for a list of the mods but I could not find one. Guess I will have to wait and call them.

Ths364, thank you for your post, it makes me feel easier about getting the two old timers in spec, without taking a bath. Do you mean, put them back in the stream with the upgraded parts, or put the old ones back in? I have been listening to them so the caps should be reformed well enough to last a while if I mean to take them out then put them back.
