The Shuguang Natural Sound 12AU7-T matched pair can be bought from Shuguangs on ebay for about USD67 inclusive worldwide shipping. They also have a normal range for the 12AU7 at about 1/3 of the Natural Sound price.

Hi guys (Dogmatrix / desertblues)   I have very limited experience and don't write really well but I will try my best to describe what I am hearing from the WA7/tp with the recently acquired Shuguang Natural Sound 12AU7-T. These are very initial impressions, gleaned from just about 6 hours...

  Just received. A matched pair of Shuguang Natural Sound 12AU7-T tubes.

@Currawong I want too. Never posted on this thread but have posted a few on other threads. Thanks.

  atsq17. Well put. Your concluding paragraph summed it up nicely. +1

I got my WA7tp about 2 weeks ago and it is working fine without any of the negative issues highlighted by others previously. I am not really that good at describing what has improved in terms of sound but to put simply, everything seems more defined now. I would really hate to think that this is...

I got my Geek Out 1000 in a timely manner. As for the Geek Pulse/X/Femto/$1M Instant upgrades, I have yet to receive the survey though. Sent LHLabs a ticket yesterday.
