Audio Horizons TP 2.0 Preamplifier

I recently looked at a current ad photo of a TP 2.1nb preamp and the photo shows the power supply board without the added two caps and with the extra two diodes. If this isn't current, why hasn't Victor updated the photos as previously mentioned? Current photos would help in eliminating confusion in identifying the differences between the original 2.0 vs. the current 2.1. The current photo does show the new caps on the line board. I'm contemplating retrying the new caps in the outputs vs. the original Hovlands as I heard a bigger difference in the wire harnesses than anything else. YMMV (O:

Sherod, I have asked Joseph to update the interior photos of the TP 2.1n and nB, at least in the ads. We are soon going to thoroughly redesign the web site.

On another note: Given how frequently the Audio Horizons preamplifier is compared to preamplfiers costing far more, as recently evidenced by the posts comparing the $3270 TP 2.1nB to the $9000 Modwright 36.5, Joseph and I have been entertaining a further extensive upgrade that will still keep our top of the line preamplifier under $4000 but hopefully end some of our auditioner's reservations when comparing our top of line 2.1 to more expensive units. These plans are still on the drawing boards, but theoretically what we envision will yield substantial sonic benefits. The present versions would not change; we would just add another layer of excellence at the top. I would appreciate hearing your thoughts not only about such an upgrade but any thoughts you have about what you think should be added to the present preamplifier to raise it to an even higher level of excellence.

Thanks for you support.

Total heresy here but I'll toss out the suggestion anyway:
optional tone controls (mainly the ability to roll off highs for bad recordings). I use it on my McIntosh C46 judiciously
and find it hard to live without. (Just try listening to early Beatles without it.)
There is an underground demand for this, even if it degrades the performance a bit.
Even if you don't use it for your speakers, it's great for headphone listening (Grados and AKGs really benefit from some roll off, as do many speakers.) I like to feed my headphone amp from my preamp to get remote volume control capability (most headphone amps have no remote),
and the treble roll-off is really needed sometimes.
As an option, this would be great. Of course, there should be a bypass switch. I think it would set your preamp apart from the field, as no competitor offers it (except Mac and Accuphase, as far as I can see.) Thanks!

Victor i like your idea for 2.1 and will be checking this thread for the release of your new upgrade. I could not be any happier with my AH preamp. I know if you have ideas for making that fine unit better i am all for it.
On the input side i would like a phase reversal switch. Vinyl is my front end of choice for superior sound and some lps are pressed out of phase, a phase SW would make life easier.
Rgs92 i am also a Beatles disciple and read you post on the early recordings. Have you tried the MFSL or the English blue box recordings on vinyl, no problems with upper frequencies. I was going broke trying to find early pressing that had good sound. I still give early lps a shot but enjoy my reissues better sound wise.
