should i go with kt150's now or wait a bit??


simple question folk's,    I have two jolida 502 amps running in mono.  kt120 tube's with about 200 hours. just broken in lets say.  this is almost going on two years now so I guess Im not listening as much as I should be. I will take care of that!!    the amps are running the top end of my infinity 1b speaker panel's.   mid's and high's.  no bass work here. so the question is is it worth installing kt150's at this point in time.    for $600, I would need eight of them, what kind of improvement in sound would I get.  with just 200 hrs on 120's would you run them a little longer to at least get some use out of them.   everybody like's the 150's for the solid bass they get out of them but I would not see that running the mid/tweeter panel.   what would you guy's do if you had the $600 ready to go??  (don't answer that)   can we assume in time the 150's price will drop a little more and just wait it out .   I know it's such a tough decision here, just help me out ok. thanks

o, i have plenty of confidence dweller, don't worry about that    its the $600 i'm thinking about spending and not getting much results.
Hi Tomtab

I own a Jolida JD502P amp and I made the jump to the Tung Sol KT150s a couple of years ago and was SO happy I did. Previously I had the Tung Sol KT120 and the sound was meh compared to the KT150s. To me the KT150s in the Jolida give you sweet midrange with wonderful bass. Sell those KT120s and use those proceeds to the KT150s.

Message Wolf_Garcia here on audiogon too. He has a Jolida JD502P with KT150s installed as well.

Thanks
I hear you jed. thanks for the input.   im leaning that way. just wanted a few audiogoners to lean me that way.  such a shame, only 200 hrs on the 120's

Dweller is perky huh? Man...Keep the 120s as backup maybe…can't hurt. My trusty 120s wore out after 3 years in the aforementioned (Jedinite…dude has great taste in amps, as does tomtab) 502P, and the 150s had just become less expensive so I got a quad...in they went and after over a year they continue to sound friggin' great and I hope they last as long as the 120s.

I just read a thing in a recent UK mag (HIFI News or something) where the reviewer, who loves (I mean REALLY loves) his Audio Research Ref 75 with KT120s, reviews the new AR GSi75 integrated. He goes nuts because although the new integrated is supposed to be the same power output as his amp from the same damn company, it blows away his Ref 75 in term of power and control over his reference speakers…he's absolutely sure it's the KT150s making the difference although it is a different amp of course…still...Besides, they're shaped like pickles, they're larger, and amp designers are all over these things so what's not to like?
