    AFAIK the TA2020 chip cant be tunred into a mono-block unless you just use one channel of one amp for each speaker.
    I would be interesting in a Power amp version though, Really impressed with the Amptastic TA2020 with my 80dB Kolts.

    The biggest problems I had when I borrowed Jerrys were the light being to bright and the unit being to small/lightweight as with the cables on the back pulling it backwards and lifting the front up. I stuck a Polished Agate Geode on top!
    Maybe a slightly larger (Deeper) case with a little more weight might help.

    Don't know whether it's strictly relevant here but I have 2 x TA2020 Mini-Ts which are fed from a custom made RC source selector put together for me by Sean at Custom HiFi cables (whom I can highly recommend ) on which I deliberately requested 2 sets of output terminals for just this purpose. One Mini-T is fed by the left channel from both outputs and the second Mini-T similarly with the right channel.
    Works fine for me .
    FWIW both the Mini-Ts are powered by LiPo batteries and I think it did improve the SQ over the previous linear PSU through JLH Ripple Eaters.

    My System:
    Power: Belkin PF40, Custom.hifi.cables Hydra and DC PSUs.
    Sources: Self built HTPC with Xonar ST sound card, NAD T585 multi disc player, Sony BDP-S350, Squeezebox Touch, Techncs SL1210 (mod'd) + Nagaoka MP30, Thomson Sky HD box.
    Amps etc.: 2 x Mini-T amps, MF-X10D Valve buffer clone, StanDAC 7520/Caiman (mod'd).
    Speakers: Mission 774s with added super tweeters
    Cables: best I can afford and likely to change except Homar's RF attenuated co-ax's and Mark Grant USB and HDMI cables. I also like silver i/cs and speaker cable.

    That's not monoblocking. That's bi-amping.

    going slightly off topic -but staying with t amps....I ordered a battery pack for my bushmaster.The BM went back and I was left with the battery pack, It just so happens to work with my original temple audio bantum. Sounds very good too, lasts about 4-5 hours in conjunction with a active pre.
    My mini T is my favourite amp in my system BUT the bantum just does something really pleasant and warm......

    Yep, Chris, I did realise it was different, hence my opening sentence. The thread is about Mini-Ts so I thought it might have some relevance for some members.
    Cheers,

    So did you try it the other way - using one amp for bass and one for treble?

    What did you find was the effect of using them left/right?

    Yes Chris,
    I did try it initially with one doing the bass and one doing the treble and it was fine. Just to see what it sounded like I then had one doing the left and one doing the right and, to me, it sounded better so that's how it stayed.
    I now have my HP amp doubling up as the sub-woofer amp so that is how it will remain for the time being.
    One minor benefit, but not really worthwhile in it's own right, of having one doing left and one doing right is that it gives me a bit more freedom when deciding where to place my listening chair .
    Dave.
    BTW I had already bought mine, as a pair, direct from HK/China before the UK GB was proposed so mine may be different versions from the GB ones.
