Thread: Bybyte.com's DTA45 Amp Good or Bad?

i am just not crazy about that amp..

it is only 2 ch, so you need to understand series/parallel wiring to get a correct end-load on the amp..

and it's class-t architecture means that it has a higher thd then a class-d or a/b amp, which rules it out as a "audiophile" quality amp...

what do you think of the amp9 from 41htz?

-The class of the amp has nothing to do with what makes it "audiophile". I would prefer no company to ever use the term audiophile to sell something. If you are into audio, you are an audiophile by definition.

-THD is always dependent on the power level. All amps have varying THD levels and as you reach the limits of output power the THD will skyrocket during clipping. No amp is immune to this.

The real question is, does it have enough power to avoid clipping for someone's use? For the people who are satisfied with a typical aftermarket headunit power amp, most likely yes.

They have a weird way of trying to market their product with the wording. I only see 2 channels.

With 42W input @ 12V (and possibly 50W @ 14.4V), hence a likely max output of 30W to 45W, "Strong enough to power 4x45 watt" means just that. (I refer to RMS values - peaks etc are meaningless unless perhaps defined and substantiated.)

I've been working with Amp9-BASIC amplifier from 41hz. I bought it pre-assembled. The sound quality is pretty good, although I don't have any high-end speakers to hook it up to. It goes pretty loud - I might have to put a limiter on volume in Windows so I don't accidentally turn it up all the way and blow out the speakers. Also, the amp accepts variable voltage (12-27) so you don't need a voltage stabilizer (although I bet it couldn't hurt). All in all, I'd recommend it - just make sure to install a big enough heatsink on it.

I have been unable to find the pre assembled amp9, there out of stock and have been for awhile at 41htz.

Does anyone know where else to get one? (assembled)

Looks like the DTA45 should be the next item i do a product review for. There's a lot of information on the board about it, but it seems for the most part negative and "specification" based. Lemme see if i can get one and compare it to my current audio setup.

I agree with soundman, that if you have 4 speakers, it's better to just get a 4 channel amp. However, to be fair, the only "i've used it" response regarding dta45 indicated that it was pretty good.
