Default Best Tripath Amplifier for 100?

Hi everyone!

After being impressed by the sound quality of a Sonic Impact T-amp Gen 2, I am now looking for a higher quality amplifier for 100 max (including shipping). Preferrably something with better bass and sound quality than the T-amp, and maybe a bit more power if possible. Could you recommend one with a good price/performance, and a place to buy it.

I can do some assembly on my own if I have an amplifier card and a fitting nice quality box for it, but I can't do anything like surface mounting of components.

I have been looking at these:



But I don't know which one that sounds best. Maybe you have better suggestions? Thanks in advance!

Those kits look good, at least they seem to have good parts etc., and will probably sound better than the T-Amp - however, they have basically the same power output as a Sonic Impact amp. This is because the maximum voltage is basically the same. The Sonic Impact handles 12-13V max, while the TA2024 handles up to 14.6V. It's not a great difference, all in all - you get up to 1.5dB more clean power.

If you want a bit more power, I'd look at amps using the TAA4100 or TK2050 chipsets.

The TAA4100 can do up to 24-27V for ~50 Watts per channel, and is also 4 channel, so you can biamp or power a subwoofer + satellites with one amp. It's a very versatile and useful chipset, and it sounds good.

The TK2050 chipset can run at up to 36V, for ~80 Watts per channel. It's higher power, and the audio specs are also slightly better. The audio specs are excellent, really, it sounds markedly better than the 12V Tripath chips like in the best-known Tripath amps.

There are various implementations. I have only tried 41Hz - http://41hz.com/ amps myself, but I don't hesitate to recommend them. The 4-channel TAA4100 chipset is available in the 41Hz Amp9 and Amp9-BASIC, for ~55 each. The Amp11 monoblock has the TK2050 chipset, for ~35 per monoblock, or 70 for a stereo pair. These aren't pre-assembled kits, but there are builders who will build for you, some of them at the 41Hz.com forums. I'm not certain that you could get a pair of built Amp11 monoblocks for under 100, but it's possible.

Here's a link to where you can find builders at the 41hz forums: http://41hz.com/Forums/forum.asp?FORUM_ID=21

But as I said, there are several implementations available, and maybe you can find something prebuilt that works better for you. Those amps at Audiophonics look to be good boards - do they carry any amps built with the bigger Tripath chipsets?

I want to say that I'm not affiliated with 41Hz in any way - I'm simply very happy with their amps. Their build instructions aren't perfect for a beginner, but if the builder has some experience, you'll get a very, very good amplifier.

Audiophonics also have this amp built on TA2022 that packs 2x60W, with a remote and LED display, but thats more than twice the price.

Jas? Det visste jag inte

I have pretty much decided to go for the Audiophonics T-amp TA2024 2x15W. It cost me 72 including shipping and the build quality seems nice. Been looking all over the web for something better at this price but I can't find anything that beats it (not something pre-built anyway).

However this amplifier seems to come without a power supply. The audiophonics site says minimum 1A. I have heard some say even 0,5A is enough.
How many Ampere do I need so that the power supply won't limit the sound? Is it as simple as this?; the amplifiers max power is 30W (2x15W)? So 2,5A * 12V = 30W?

Sonic Impact uses a line lump SMPS rated 14V@3.21A = ~45W for their T24, which uses essentially the same amp:


It's the exact same PS used by the Psyclone Nodus I've been hacking.

check this: http://41hz.com/Forums/topic.asp?TOPIC_ID=678

However you've basically got it right, as far as I can tell.

If you're going for ~14.5V, the absolute max output per channel is ~25 Watts according to the 41hz page above. A ~50W supply is certainly good enough, and you can very probably get by with less.

Personally, I found an 80W transformer for my Amp6, and a 90W SMPS for my Amp6-BASIC. (I think I can recommend the SMPS route - it's cheaper and lighter, and doesn't sound worse.) SMPS supplies, around 12V, and under 100W or so, they all cost the same really. At least in Iceland ...

Bleh, too complicated - try for 50W 14.5V, but you'll be fine with 30W 12V!

Also take a look at Lars Christiansens D-class products, they are very nice for under 100USD

It could be AMP2, but it is a kit, not ready made...
