Brought to you by the company that started the ball rolling with Jolida modifications!! Nobody knows Jolida products like Response Audio. Nobody. Looking to bring out the most your Jolida amp has to offer? Be sure to check out our exclusive Bella Extreme 3205 MKII modification. DETAILS   Anybody can change tubes and add a few things here and there. What you get with the Signature upgrade is basically a complete rebuild using only the best internal components based on critical evaluation and testing. Plus, no matter how old your unit is, we offer a full 1 year warranty on our work. Why spend your hard earned money on a new amp that could set you back thousands of $$$$. Transform your Jolida 202, 302, 502 or 801 "A" or "B" Series amplifier into something that will compete with many of today's high dollar pieces for a fraction of their cost. You will think you just purchased a brand new amp and still have money left over for further system upgrades. When your unit arrives at our facility, it is first tested to assure it is functioning properly before we continue on to remove ALL internal components. When we are finished with our upgrade, the only remaining original parts on your amplifier is the transformers. The reviews and customer feedback says it all. Check out our Feedback Pages as well as the review of our Bella EXtreme 3205 amplifier at EnjoyTheMusic.com.

It is a good value, and can satisfy critical listeners. Because it can be used with a variety of output tubes, it can easily be configured to the listener's taste and system. What I find most exciting, however, is that this level of performance can be achieved for such a relatively reasonable sum..."

I have listened to it almost exclusively since its arrival and do not find myself continually longing for something better. With high reliability, I continue to be impressed with its performance. It is a good value, and can satisfy critical listeners. Can easily recommend it to both the newbie and well-seasoned tube audio aficionado. — Nels Ferre
