Just picked up a class T amplifier

[eatontrifles]

I've had a set of Tannoy MX1 bookshelf speakers sitting for a while - on a bookshelf - looking pretty but sounding quiet and after reading about the Vamp (http://www.thevamp.co.uk/) but not being convinced by it's tech specs, decided to do something to bring them back to life. The speakers are decent enough although they're not the last word in quality so didn't want to spend a lot, also because I've already got a decent main system elsewhere.

After researching a few options (mostly on Amazon) I ended up buying one of these for £32; https://www.amazon.co.uk/gp/product/B017W13O5W/ref... and added an unused Logitech bluetooth receiver that I had lying around. The amp is a tiny little thing, dead basic but nicely put together with a single pair of RCA inputs plus proper speaker posts on the rear and a latching power button with a nicely weighted volume pot on the front. The sound quality is excellent, I'm very impressed - I'm used to listening to speakers worth a lot of dosh in my professional world so know what good sounds like. At 20W per channel it's plenty loud enough for the living room, although I won't be cranking it up that high anyway.

Has anyone else dabbled in these little amps?

Few years ago I got one and also linked up to some bookshelf speakers and a logitech wireless speaker adaptor, must admit it sounded just as good as my Onkyo AV amp I was using before. Using Sonos Play 5 now due to space but tbh sounded better than the Sonos.

I went for this one

Yes, I have a t-amp (dayton audio) https://www.amazon.com/Dayton-Audio-DTA-1-Digital-...


It's an impressive bit of kit, being able to run on 8 AA batteries.

Running a pair of B&W DM303 bookshelves my initial impression was that it gave a very detailed, clear sound, with plenty enough volume for listening in my apartment.

After a while, it dawned on me that the treble was hurting my ears (thread on the subject here: http://www.pistonheads.com/gassing/topic.asp?h=0&a... )

I switched back to my old technics amp and that made a big difference. So I think it somehow emphasises certain treble frequencies.

I now use it occasionally outdoors running speakers off batteries for barbecues and camping etc. It pisses all over a speaker dock for this purpose.

I've been using them for a few years now. I have a Topping TP-22 and a small single input Sure.

The Topping is hooked up to a pair of i.us i700s I got for a very good price and they really suit each other.

The Sure is used with a pair of Wharfdale Diamond 9.0s at the moment for a smallish desktop set up but I am not totally happy with it and have been considering options to improve it. The speakers are past their best - suggestions for small, easily driven book shelf speakers welcomed.

Just out of interest, how long will it run on AAs for?
Have thought about using one of these outside for a while now.

If using good batteries then ages.

I recently put 8 energizer lithium batteries in it that have been sat in a rarely used handheld cb radio for over three years.

Connected the amp to some low sensitivity kenwood bookshelf speakers and played at nearly full blast from around 4pm to 3am.

Then i put them back in the c.b. :0

So yeah, for this purpose they're awesome. Use high sensitivity speakers if you want higher volume. I'm gonna try it with some old p.a. speakers soon

Good to hear that there are a few others with positive experiences, I'm genuinely impressed with mine.

They are good, especially if not driven too hard. They need a decent power supply. 8 x AAs will make it work but a car battery is MUCH better, especially as you turn it up.
