Running off of 2 seperate 12 volt dry-cell 7 amp batteries. WOW what a step up from just running the amps straight from the signal source. It also now gives me the convenience of 6 inputs. **Audio Heaven** Anyway enough of my ranting, I can let the boards go for US$20 each.. They work of of DC or AC and you can switch polarity with no effect.

Hi, I'm also using Arjen's TA2020 board, it's a nice board with good output inductors as standard.

How much difference did your valve preamp make? I'm tempted to order one, but I'm not really sure on what tube to get, as I know very little about tubes... What tube are you using and in what way would you say it improves the sound?

Hi, I am using a clone of the Maranzt 7, from a crowd called Teemad Audio who like most of the resonably priced vavle gear is based in China. I bought mine of of Ebay on a buy now for 170 pounds. It arrived very quickly and is quite smart. It also has 6 in and 2 out which is ideal for B-amping as I wanted to do. The phono sockets are very high quality and the build is plain but very good. \
What do it give to the sound. Well first the T amps do nor run out of breath as they can do in passive mode. The base weight is considerably better and female voices seem to just be there for me in the room.
Hope this helps, a little later i will also try tube rolling with better matched pairs which from what I have read can also make a real improvement for little cost.

Thanks, I think I'm going to try one of ArjenHelders tube-pre's just to see how I like the tube sound, before getting anything else, I've already spent too much on Tripath amps, I think I'm becoming an addict!
