SI super t amp.

[gvr4ever]

Has anyone had one fail on them? I didn't have such good luck with the cheaper plastic amp, but after looking at the much higher quality of the super t amp, I want to give it a try.

Before I get burned again tho, I wanted to ask how big brother is holding up.

If you did have one that failed, how many hours did you get out of it, and how loud did you turn it up?

Please only respond of you bought the SI super t amp.

Thanks

I've had one for about four or five months, works fine on a 4 ohm load, sounds great.

But if it breaks, I'll let you know.

I've modified a number of these. Easy to do, much easier than the little guy.

The board is bigger and better laid out, more robust. You can lift the pads, if you use too much heat, but it's harder to do than on the little S.I.

Bottom line:
I've killed about 6 Sonic Impacts. Never hurt a Super-T. Go for it!

Did you ever post an official list of the mods?

Thanks!
I need to update and elaborate that Super-T page, among my million other projects.

The Super-t is a nice amp. Much better sounding than the little Sonic Impact and easier to modify.

Is it worth $100 more? In some cases, yes. If you are going to buy a nice case, connectors, power supply, switch, etc. for your S.I. project, then you should look at the Super-T. It has those things already, as well as being easier to modify and more robust. And you may end up killing an S.I. or two, you wouldn't be the 1st one!

If you want to build from scratch, get a Charlize or one of the 41Hz kits. Very nice amps.

Time to revive this thread?!

The October issue of Stereophile has a glowing review of this Sonic Impact Super T amp (starting p. 161) and give it a Class C Recommended Components Rating (p. 95)! The reviewer (Wes Philips) writes "The Model TA2024 Super T amplifier has proven to be som much fun and full of surprises that John's [Atkinson - the Stereophile editor] been waiting on my copy long past deadline".

The review noted that the power supply is undersized and that the amp is sensitive to load impedence ("the high frequency response is drastically curtailed into 4 ohms and below" p.162 in the Measurements section). Hopefully panomaniac (or other better than me!) have some (simple!) mods to corect these problems.

Now hopefully more people will take these little and inexpensive Class D (or T whatever you call it) amps more seriously!

I'm getting ready to order mine any day now. Just waiting till pay day.

Anyway, don't have the money for tube amps, mono blocks, whatever...

I've only heard things like harmon kardon, denon ect. I own a onkyo stereo amp, a Yamaha 5.1 amp, and a old sansui and a freebie heathkit amp.

Anyway, I had the $29 baby amp working with the input caps mod, but it was taking about 15 seconds for one of the speakers to come in 100%. I went back to check for a problem and while trying to add a little solder, I lost the pad. Opps.

Anyway, that stupid little $29 baby (with crapola build quality) sounded absolutly insain. It was no longer bass shy and clarity was insain. It kicked the crap out of my other amps.

It reminded me when I almost bought a pair of Paradigms (tax fairy sucked that year). They were hooked up to seperates. Don't remember the brand, but I was at pro audio in Lafayette,IN and it was a higher end A/V only store.

I was only listening to some vintage polk monitor speakers with the t amp. I absolutly love the sound and I don't think I will ever buy another amp or kit that isn't powered by a tripath chip. Unless I hit the lottary or something, it's the best a music lover can get who doesn't have thousands of dollars to throw at audio equipment.

The super t amp is acually just to hold me over untill I can build a 41hz amp 6 kit. Also, I'm tring to learn how to build speakers so I don't have to spend about two grand to get to the level of speakers I want.
