    "ChiFi", not seen that before, good description. I have tried the TPA3116 on my Tannoy HPD315's and in my case 12V is satisfactory with these speakers as they are more efficient / sensitive than the Rogers.

    I think Macca suggested a bit more juice may improve the bass a little and I thought he was right.

    My speakers are about 96db sensitivity so certainly not hard to drive.

    I recently bought this from Amazon. (couldn't wait for 2 weeks!). Its a 100w version if you power it appropriately.

    As far as a review goes I took it round to my dads to try with his Penaudio speakers (9k new). His previous amplification (Talk Hurricane 3/Musical First/custom valve pre's) is now for sale.

    So that's a 28 quid amp powering many grands worth of speakers replacing a couple of grands worth of amplification. The synergy with the speakers was utterly astonishing.

    Now being run off a linear power supply set at 18v. Everyone should have one of these.

    I'm surprised by that. Whilst the TPA3116 is competent in isolation, swapping back to 'proper' amplification did reveal what it misses. A lot of detail, like multi-tracked vocals for example, gets glossed over. I suppose not everyone is bothered about that though.

    You're not the only one who was surprised Martin!

    I've tried to better the aforementioned amplification with offerings from Ming-Da, Musical Fidelity, Quad and the old Talk always prevailed. Until now. I think the most surprising thing was the dynamics. It goes from a distant ambient note to a gigantic swell of sound in an instant.

    The old man's hearing is not the sharpest to be fair and he mixes classical with 70's rock. Maybe some slightly more modern recordings will show any weakness' it has.

    I agree prolonged listening is required to better understand what might be missing.

    Could you give an example of a good test track to determine what you suggest could be missing? 10CC - Not In Love (beginning part with layered vocals maybe??)

    Cheers.

    .
    I noticed it with about the first thing I played after swapping back to DCB1/Krell which was a Robert Plant record 'Principle Of Moments'. I think it is at the start of the second song, Plant sings for a second or two before the rest kicks in and the multi tracking on his voice was obvious, no need to listen for it.

    It wasn't obvious with the TPA3116, not sure if it is still there or not with that amp, but it certainly isn't obvious. It is a good quality recording though.

    Thanks I'll give it a go.

    The speakers really seemed to react well to the change so possibly a re-capped/serviced Talk would be an obvious winner in a back to back comparison. It has been sitting there for best part of 15 years to be fair . . . .

    I'm sure the Krell is always welcome back in after something (momentarily) takes its place!

    Not all TPA3116 amps are the same, not my findings but a friend is a wizard with these things. I'm certainly happy with the one he put together for me.

    I bought mine for a second system, but it's been driving my big Tannoys with no bother and sounding ridiculously good.
    About to get one of these.
    Did this come witt 25v or 35v caps do you know?

    Cheers
