For more punch in the bass, IMO you need either solid state amplification, or perhaps a KT88 amplifier.
In general, I agree with Onhwy61 that you might be best served by keping what you have.
However, there are a few options if you want to experiment: PrimaLuna Prologue II, Classe CAP-150 or CAP-151, Unison Research Unico P, and Portal Panache.
All are within your price range if purchased used.

Do nothing. At your budget you won't be able to get the changes you're looking for. Remember, you stated you loved the amp. So just continue to love it and forget about those sonic qualities you think you would like. |
Sorry -- to be more precise, the speakers are Quad 21l2s -- http://twochannelaudio.com/Quad21L2speakers.htm---
If I sold the Jolida, I guess my additional budget would be around $500 above what I could get for the Jolida 302 on audiogon.

Thanks all. I am running them with a pair of quad 21l2s. What other amps would you recommend I listen to? To receive useful responses, we need to know what speakers you are using and your budget. |

For some reason, Jolida always puts crap tubes in their units. I've never seen a Jolida yet that didn't benefit from replacing the stock tubes...
However, I can't stand the Mullard reissues. They are nothing like the real thing. Start with replacing the driver and gain tubes. Leave the 6CA7/EL34's for later.
Check out www.upscaleaudio.com www.echohifi.com www.tubesandmore.com or get unrealistic and check out www.tubeworld.com or www.tubeman.com for expensive choices. |
I'd agree with Tvad - you won't get the improvements you are after for a $200 mod as described. I also don't think they'll come swapping tubes to any great degree, and great NOS tubes are pretty expensive and somewhat risky. What you describe as your goals, a fuller sound with better staging and bass, may indeed be realized going the route of a KT88 based tube amp. I've owned the 302B and have listened extensively to two friend's 502B's and I could tell you the fuller sound and better bass would be realized there. I don't know that the soundstaging ever occurred to me as any better via the KT88 Jolida. You might try listening to other options in the same ballpark (Cayin, Prima Luna, etc.). Don't rule out SS completely either...though they may not have the soundstage depth they can certainly achieve width and definition and will likely give you improved extension as well. There are tradeoffs either way. You just have to listen for yourself and see what works best for you. |
Underwood HIFI has an ad for a Jolida 502b right now. It reads in part:
"We can also order the amp(502b)set up for EL-34 tubes.
In this configuration it does 50 watts per channel and has the warmer more liquid sonics of the EL-34 while sacrificing some of the tighter more controlled bass and better detail of the 6550/KT-88 tube."
Mods IMHO won't give your EL34 tubes more punch.
I would look for a different amp with kt-88 tubes.

what speakers is this amp driving? |
A good tube roll is what got me he he hooked. I roll in the tubes,I think will best compliment the fundamental sound. I keep several hundred tubes as a collector and tweaker. Tube prices are coming off silly high prices so give it a go.
If OTOH you hate the sound forget tubes and cables and do what they said- save you pennies and get a deifferent amp. |
|
Rather than throwing money at experiments with mods or new tubes, you might want to consider just selling the 302 and spending an extra $400-$500 to get something like a used Rogue Cronus, Cayin or other inexpensive tube integrated that has more the sound you're looking for. If you have shops in your area where you could demo other equipment, I'd definitely take that route first. |
In gardening you have to throw money at plants and see what works in your garden. In cooking you throw money at food, apliances,pots and pans and see how well you can work with it. In audio you throw it at tubes, cables, cord, amps, etc. and hear how good it can get. People can give you advice based on their experience and their or friends systems but it is still about their ear's not yours.
Sorry but sometimes the plunge works and sometimes it doesn't. |
Yea -- just starting to get cold feet about the tube upgrade. Hard to commit the money when I really don't know how the different options are going to sound. |
|
I don't believe you're going to realize the benefits you desire for the $200 mod (or perhaps any mod).
A modification generally increases resolution and lowers noise floor, which can increase the size of your image, however I'm dubious of a $200 mod.
IMO, you will get the results you want with a better amp speaker match, especially where bass is concerned. |
