Audio Horizons TP 2.0 Preamplifier

I'll look into a used, calibrated B&K 606.

It's easy to calibrate the B&K 606. The manual has instructions. It requires a resistor (value specified in the manual) and a screwdriver. It's all done without opening up the tester. Simple to do. So don't pass up a B&K 606 in otherwise good condition only because it hasn't been recently calibrated.

Hi guys,it's been awhile.Recently acquired a quad of 6H23 Russian military tubes.Manufactured in a collective factory in Kaluga,not Kahula(joke)they are a drop-in replacement for the 6922 tube.Sonically they are as good as my Siemens ECC88's but do not have the finesse of a CCa.For something different and everyday use they're a perfect fit.

It's interesting to me to note that recent comments on this thread concern tube rolling.

One of the attributes of the TP 2.2 that most enthused the PositiveFeedback reviewer (see my 6/5 post for link) is the responsiveness of the TP 2.2 to tube selection.

We are living what the reviewer described.

Whatchu talkin' bout, Mark? You sold your preamp. Are you going with The Dude now? I would love to hear your impressions. (o:

It has happened twice!
Positive-Feedback has published a second review of the Audio Horizons TP2.2 preamplifier.

Something else happened twice!
Both reviewers liked the preamplifier so much that they bought it.

I think the reviews are interesting because they come at the preamp from different perspectives. The review published last month focused on the engineering qualities of the preamp. The review this month focuses on the user experience.
