Upgrade Tube Integrated or Buy Separate Pre-amp?


My first taste of tubes came last year in my Jolida 202a integrated. I'm hooked for sure, and looking to upgrade and some point soon. The jolida sounds really good, however my concerns with it are the typical ones. These are mainly around clarity, ability to handle complex music/speed and bass. Simple girl/guitar music sounds incredible, as expected. Classical is decent. Rock is pretty much awful.

I am considering 2 upgrade paths: 1) Buy a used tube pre-amp and use with the jolida as a power amp or 2) sell the jolida and purchase a used higher up integrated (PL, Cayin, Rogue, etc).

Budget for a used a pre-amp is about $700, used integrated is about $1200.

In this price range (for used) are tube separates or a different integrated the way to go for value and sound?

Assuming I were to buy a used preamp to be used with the Jolida, any recommendations? To make it fairly easy, I'd be looking for tubes, a remote and under $800. I doubt there are many good contenders given those requirements.

So, to restate my original question, I am wondering if in the price range of around $1500 used is there better value in tube separates or an integrated amp? Maybe this is too vague a question, I realize there are a lot of variables. It does not sound like upgrading my Jolida is the way to go (since I can't do the work myself, the return won't likely be worth it). Can I get something that's a HUGE step up from the Jolida for $1500, or would I have to go higher for that to be a slam dunk?
if you plan to keep the jolida, changing to better parts would definitely improve.
If not, suggest you purchase a better int amp.

Nobody can answer that question for you Nolitan. Getting the best sound possible out of a system involves so many variables it's almost mind boggling. You might relocate your speakers and get the type of results your looking for. On that subject, matching your speakers with the correct amp is about as critical as it gets. If you want to play complex music, your amp must be able to provide power on demand, and some speakers are much more demanding than others.
Very fair point on the speakers question. I am using Triangle Comete XS speakers on sand filled stands. I've had them for years and love them. They are easy to drive, very fast, and believe should be able to do what I want when paired with the right electronics.

I was told by several sources that these speakers match very well with EL34 based tube amps (part of why I bought the Jolida). They are a good match I believe...just not getting the goods on complex music.
