I have been contemplating getting a decent tube tester. Maybe I'll start looking for a good used one. Thanks.
A review of the new TP 2.2 preamplifier has been published at Positive Feedback Online. Here is the link:

The review is very favorable. Here is the thesis of it.

"I've not come across a product that challenges my notion of what one is paying for, and what one is paying extra for. And let me cut to the chase: this may be the best value in all of high-end audio."

Ryan Coleman is the reviewer.
I had the privilege of beta testing a new product from Audio Horizons a while back. It is the RTS coupler which has just been listed on A’gon last Sunday.

As a long time user of Audio Horizons products (2.0 preamp upgraded to 2.2 and 3.0 DAC upgraded to 3.1) I have always been so impressed with what Joseph and Victor have created. Of course we all know that their customer service is second to none.

I would encourage all of you to go to the ad for the RTS coupler and check it out. I won’t reiterate my comments about the product here as they are clearly elucidated in the ad. IMO, it is an amazing product that warrants an audition. I know that I could not be without it (actually I have several in the system).
I put in my CCa's about the same time you did, turn the preamp off when not using and have it on about 6 hours per day and the cca's still test very well on my tester and best I can tell no degrading of the sound. I picked up a B&K Model 606 tester for about $100 on ebay in excellent condition at the time I got the cca's and find it perfect for my purposes and easy to use. Hope this helps
