Can't answer for Zaikesman, obviously, but I do have experience with tube gear including Jolida. Jolida do make some great products for the money they charge. Most are built in China as I understand (the company itself is based in MD). The quality is more on the scale of a mass-produced item rather than the more hand-built level that much of the higher-priced tube gear reflects. The Jolida amp I owned was their 302B and was the first tube amp I owned. It was well built but certainly did reflect that distinction I made. If I compare it to the Cary and Quicksilver gear I now use one could certainly tell the difference in quality upon examining both products. I found the Jolida to be immensely enjoyable coming from SS, and would certainly recommend them as a solid introduction to tubes that has pretty good resale value as well, though you may even like it enough to hold onto for a while. You can certainly purchase more refined, hand-built tube products that sound even better still, no doubt about it. You will likely have to add some more $ to your Jolida price tag though, and or buy used gear (which is not necessarily a bad thing). The Jolida 302B I had did yield much of the wonderful qualities tubes have to offer without a huge $ commitment. Eventually it made me yearn for more of what I loved about those qualities. Some of the things that will make the difference in price and quality of tube gear are just how well the amp is designed, the quality of the components used in the amp from capacitors, to transformers to attenuators to tube-sockets to wires and more. Also how well constructed it all is....how much care went into the assembly...is it point-to-point wiring or are printed circuits utilized...are the tranformers hand wound or machine wound and sourced from some other country. As far as three channel amps, I'm not sure if you are asking about Jolida's additional output for a subwoofer(?). I think the use of a subwoofer is a matter of taste. Nothing wrong with it if done right. The Jolida output (subwoofer-out) does not put out much power as I recall so going that route may not give all the punch of going through an separately amplified sub. Perhaps you may be referring to using a center channel, which I have no experience with, but understand it can also be done very effectively. Anyway, hope that input helps.
