Jolida jd-502p

My mistake; the 12AT7 Mullard is a CV 4024, not a CV 4004. The 4004 is a 12AX7..

Yeah man. I've thought about the mono 502p path but my speakers seem to be efficient enough to make me not want to bother...and I don't really have the room with my current rack space...HOWEVER...let me know how that works out as I've never heard anybody's thoughts on 502p monos. And I could get a different rack...hmmm...

Hi Zkidd

Definitely keep us in the look how it goes with the 502P monoblocks. What speakers do you have that warrant the power of 2 JD-502Ps? I own the Jolida JD-502P as well and am really happy with it. I couldn't resist trying NOS tubes and ended up with a whole GE Joint Army Navy tube complement in it now. In my system the differences are subtle between them when I had the Tung Sol KT-120s in the Jolida. There was a more pronounced difference bass wise and imaging wise between the GE 6550s vs the Penta Labs KT88s.

With your Jolida also check out the Tungsram 12AX7s with either gold or platinum level matching. Another Jolida 502P owner here has the Mullard CV4024 and the Genelex Gold Lion KT88s too and he was really liking the Tungsram 12AX7 match-up with all.
