However, even rock music sounds great with a tube system with a little bit of cojones.
I started in the same place about 8 years ago. I had a Parasound amp running off of a Sony ES receiver. I got that Sony out and put a Conrad Johnson PV-10AL in there, and I was in heaven (for a little while, at least).
That was about the time I stopped looking at specs alltogether.
Try something in your home, if at all possible, and I'd recommend either a tube pre and a solid state amp, or hybrid integrated with ss amp stage and tube pre stage.
I had a Unison Research SR-1 hybrid integrated that was absolutely badass, however I preferred an all-tube design.
Check out the SR-1, on Upscale Audio's website here, it's so cool.

very highly recommended by me.
The Pathos Classic One hybrid gets a lot of good press, here it is:

Never heard one, but it is a Stereophool "Class A" integrated, if that matters to you.
I use a Rogue Tempest, however it has a lot more tubes to deal with, but it is an auto bias design, meaning that you don't have to fiddle with tubes as much as with some other amps. I love it. Really. LOVE.
I have listened to Jolidas and enjoyed them, but since they must be user-biased (I think, someone correct me if I'm wrong) and there is a TON of difference among sound quality of their products (Probably attributable to the difference in power tubes used), I wouldn't recommend them for a first foray into tubes. BUT, I've never owned, just borrowed, so I'm not the person to ask about Jolida.
There are a ton of rediculously inexpensive import tube amps and preamps around here, for some reason, however, I have no experience with any of it (Cayin, Consonance, Radii, others). If it were me, I'd stick to a well established company with a good service record, and a repair facility in the US that's been the same for a while.
I'd hate for you to get a bad taste in your mouth regarding reliability issues of tubed equipment solely because you might not have gotten a well-executed piece.
Whatever you decide, try to get something, ANYTHING into your house. Listen. I think you'll agree that there is something magical about tubes.
good luck.
