Which is better, Jolida or Cayin?


I want to ask what your opinions are on these two integrated tube amps. The two amps are:
Jolida Modified JD-202a, modified by Underwood HiFi
The TAD-Cayin TA-30, also modified, by 2baudio.com

Who has a better circut design? Or transformers? And over all build quality?

Thanks.

Maxx - just wanted to comment briefly - from where I sit, I think you've taken parts of my posting out of context and have worked some of my comments over to make something more of them than what was said. If you want to discuss further, please contact me offline. You must be strongly interested in this topic, I really have little stake in it.

The Kavent comments came in a thread here that was not archived by the moderators. Some people had noticed the brand popping up on Ebay, and some people reported they had bought them or knew people who had bought them and had quality problems with their units. I don't surf the Asylum, and I don't have Kavent mixed up. The fact that the negative comments don't appear here anymore has more to do with the site's moderation and archiving practices than it does the brand. It really doesn't matter to me.
Thanks for all the opinions. I will also be looking at some used Cary, SLA-70. But I am still open to Jolida and Cayin.
"Better" is a purely subjective term. I will tell you that I've had the modded Cayin TA-30 from Paul at Bizzy Bee for about a year now and I'm extremely satisfied with it. It is now my permanent power source. While I still find myself reading and thinking about speaker upgrades and turntable/cartridge upgrades, since I first hooked up the Cayin my search for a new power source was done. It's modest 30 wpc rating actually belies its ability to drive speakers with authority and control. You know, I'm pretty sure Paul offers a trial period or "money back" deal (with a modest re-stocking fee), so you might want to take the chance to audition the TA-30 in-home. I did, and I've not looked back. Good luck.
Another plus for the TA-30. Before I recieved my Europas, it actually drove a pair of NHT VT-2s with no difficulty whatsoever. Truly amazing power from a 35 watt amp. And beautifully built to boot!
Very happy with my Cayin TA-30. Something about the circuit boards in the Jolida v. point-to-point wiring in the Cayin were a definite vote in my favor for the Cayin.
