Just got my 7XX's!! It sounds great with the amp...like holy crap does it sound superb. Thanks to everyone for recommending this amp and thanks for all the help you all have given!
Also, I've got a 12au7 Tesla valve and a 12ax7 JJ valve (the stock one). Is the stock one worth keeping? Also I'm planing on buying the supercharger since I got the amp for just 200, since I want to try out some of the crazy valves, so maybe you guys can recommend some? And until my birthday which comes up in a few months I'm going to stick with my PC's onboard dac.
