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

Hey Big Tom. Sorry to hear about your trouble. Most of my high-end adventures involved tube amps (ARC Classic 60, VT-100, Vt-100 III, Almarro 205A & 318A). I've switched tube tube front-end and SS main amp as I feel tubes homogenize the sound and make everything too smooth (even when it shouldn't be). These KT150s have me interested in tube amps once again and I may try in the future.

I've never had problems with tube performance. When I traded the VT-100 for the MkIII, the dealer told me that one of the tubes wasn't working due to a blown transistor. I didn't notice anything wrong with the sound.

My hell-pit is mounting phono cartridges -almost went crazy when the phono lead broke off and no one in this country wanted to fix it (including the manufacturer). So don't feel picked on (by fate) we all have crosses to bear.

Good luck...

thanks everyone for chiming in.  all seems to be good now.  everything working ok.  8 hours on the 150's now and the mid/tweeter panels seem to be singing.  my cd player just lost its right channel, go figure.   a cambridge 840.  good player when it was working.  but i guess their all good when working.  looking at the net I see they have problems that have popped up and i guess mine has some of them.  and that what happens when you buy a $1,200 cd player,  they shit the bed like everything else. and getting it fixed is not going to be cheap.  o well
