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?

Unfortunately my line of thinking falls along with what Phaelon said. I'm looking for a significant change, anything else to me just wouldn't be worth the expense/bother. I can roll tubes, upgrade my front end (Music Hall cdp and computer audio through Music Steeamer+), etc...but what I am really after might have to wait until I have more means.

I am thinking something along the lines of a Cary or Rogue integrated is sure to best the Jolida in all areas. This will be a large expense for me, but probably where I am heading.
Meskandar, Whatever you decide, until you do, your time will be much better spent, out in the field, listening to as many systems as possible, instead of relying to heavily on these forums. Listen; discuss what you hear; listen some more; discuss... it's a process. It can be a lot of fun.
Also, I think that you are showing good judgement in trying to avoid moves that might essentially prove to be lateral. Even buying used, over the long run, each move chips away at your finances, so that when a significant opportunity comes along, you might not be able to seize it.
