Recently, Joseph took a TP 2.1nB to Cedar, who in the past has acted as a beta tester for us, to compare to his TP 2.0nB. In addition to a number of small changes made to the 2.1, at the last minute in the 2.1n we decided to replace the Hovland caps used to a larger, more expensive proprietary brand. This decision occurred after I had written my post announcing the impending introduction of the TP 2.1. The new capacitors are so sensitive to interference that each capacitor must be individually wrapped and shielded with thick copper foil.
Cedar was so impressed by the sonic improvement of the TP 2.1nB that he asked Joseph to upgrade his TP 2.0nB and his TD 3.0n.
When Audio Horizons was founded, we had a couple of clear marketing goals: 1) to provide a clear upgrade path for owners so that when they could afford enhancements, they could upgrade the performance of their Audio Horizons components (and thus be certain they were improving the performance of their system) instead of replacing them, and 2) to shun a marketing philosophy based on change and obsolescence.
As part of this second goal, we have decided to put together an upgrade option which would permit TP 2.0n and TP 2.0nB owners to upgrade their 2.0n and 2.0nB’s to 2.1n and 2.1nB. The upgrade will not yield all the benefits of the newer model because some of the gains from improved layout can not be translated, but most of the gains will be incorporated--all those that can be included will be. There are six areas that will be addressed:
1. We will add four capacitors to reduce input switching noise.
2. We will remove the old multipath wiring harness from the RCA jacks to the volume pot and to the main preamplifier PC board and replace it with a new upgraded wire harness, which now comes wrapped in an extra isolating layer of Teflon for better noise suppression.
3. As a result of this harness improvement and isolation and by virtue of shielding the new proprietary caps, we find that the line filter is no longer necessary to filter out high frequency noise; in fact it actually introduces extraneous noise. We will remove the line filter and bypass it. This line filter was never a part of the “n” upgrade: it was always part of the original design and exists in the TP 2.0 as well. It will be returned to you.
4. We will remove the Hovland caps, which also will be returned to you, and replace them with the larger, more expensive shielded capacitors we now use in the TP 2.1n version. Our cost for these capacitors before shielding is just under $80. We think they are worth the extra cost and believe you will agree after listening to them.
5. We will diagnose and address any problems some of you have reported with ground loop issues or tube microphonics.
6. Finally Joseph will inspect the preamplifier to be certain it is operating properly.
Because of size and layout changes, it will be impossible to upgrade the chassis and faceplate.
The cost of this upgrade will be $300. Please understand, these upgrades are not a big profit center for Joseph. We are offering them so that those who want the latest Audio Horizons refinements can order them. The caps are not always easy to get so we will need you to schedule your 2.0n to 2.1n conversion closely.
I have asked Cedar to post his impressions of the sonic benefits of the upgrade. His impressions mirror our own but we thought you would like to hear them from a disinterested owner who has now lived with the upgrade for some time.
