I am thinking of a pair of these bridged and run as power amps.
They would be fed from a tube pre-amp which, while you would never have heard of the maker, you can look at here if you are as nerdy as me... sad but true!It was my first go at tubes and I found Patrick who hand built stuff at reasonable (pre-Chinese of course) prices.
Now, is there anyone here who is or has run these little babies this way?
6 Moons pretty much seem to love them...

Cannot be "bridged" in the traditional sense... - AbeCollins 11:01:37 03/10/07 (3)
I was curious about bridging the TA-10 / TA-10.1. Here's my email to Hifilogic (US reseller) and his response:
QUESTION:
" Your description for the Trends amp says these can be bridged to turn them into monoblock amps. When you do this, does it double the power output?"

ANSWER:
Abe,
Thanks for the interest in the Trends Audio products - Well the amps wattage does not double in anyway but what most folks do is to bi-amp them. The bridging only makes it a pure stereo amplifier via internal jumpers [disabling the volume pot] - but does not double in wattage. Hope I did clarify your concerns.

- How to you connect... - dave c 15:02:04 03/10/07 (2)
  ... them to your pre-amp?
  Do you have 2 outputs on the pre, or an arrangement at the inputs to the Trend, or can you just use one of the inputs in some way?
  I'm missing something here...

    I have not done so, but you may use "Y" connectors
    from the preamp to the TA-10.1. This allows the same signal to be fed into both channels of the TA-10.1.
    Then one channel's (right) speaker cables go to the highs and the other channel's )left) speaker cables goes to the lows. The speakers must have the ability to accept separate high and low cables. Usually, this requires the disconnection of a jumper that connects the high and low speaker inputs together.
    The advantage of this arrangement will allow a full 10-15 watts of power to be available for delivery to the highs and an additional 10-15 watts of power available for delivery to the lows. It may sound as if you will have twice as much power, but the demands of the high and low speakers are not the same. In the bi-amp arrangement of the TA-10.1 there is effectively twice as much power "available" to each channel.

      That was what I was thinking.

I am not sure what you mean by bridged. Neither, the Tripath based amps nor specifically the TA-10 amp can be bridged in the traditional manner. You may run the TA-10/Tripath as bi-amped, i.e. use one channel for the highs and the other channel for the lows. Thus using an TA-10 for each channel.

  ... " What's more, there are two jumpers for you to bypass the volume control and turn the integrated amp into a power amp".
  From the 6 Moons Best Of 2006 report.
  Where do these jumpers go and what do they do then?
  Do you know?
  I'm not saying you're wrong, but i think I just confused myself...
  - Jumpers. - DaveT 04:41:03 03/10/07 (2)
    The jumpers allow you to bypass the volume control, such that the amp functions as a stereo power amplifier. So, yes you can bypass the volume control.
    I use my TA-10.1 with the volume control and a tube preamp. Most of the time I don't use the volume control on the TA-10. Occasionally, I use the TA-10 control to reduce the volume. Otherwise, I use the unit as a power amp.
    I hope this answers your questions. BTW my TA-10 is stock.

    - 2 questions... - dave c 07:35:38 03/10/07 (1)
      ... hoping you have time...
      How is the volume control set?
      And...how does it sound?

        I set the volume to full on (high volume) to use the amp as a power amplifier. In this setup I use my preamp to adjust the volume.
        I will use the volume control on the TA-10.1 to lower the volume often times based on the recording of the source.
        I really don't notice in degradation of the sound due to the volume control. All I hear is the clarity and musicality associated with the Tripath amplifier technology.
        I Hope this answers your question.
