DTA-100a question

[fedja]

How is this little amp at handling not so efficient speakers, lets say 87db ?

Re: DTA-100a question

You'll get maybe, about 15 watts per channel out of it. so it should do just fine for normal listening levels.

It is a 200W supply. I wager some more than that.

Re: DTA-100a question

If it can generate 10w into your driver load (which is what?), then you'd be at 97dB. If 50w, then 104.

Assuming this is the amp you're talking about?

Unless he mistyped, yes.

Re: DTA-100a question

it's an honest 30w/chan @ ,1% thd. It can drive OS MTM loud enough to be heard over a router w/ muffs on. Guessing is no substitute for experience.

For some reason I had it in my mind that I saw a thread a while back saying that these were only capable of putting out 10-15 watts per channel with the supplied 2amp PSU? I could be imagining things, it wouldn't be the first time!

You're thinking about the TA2020s, like the little Lepai. The DTA100 is not in that camp.

See, I told you I was imagining things! - thanks for clearing that up.

Re: DTA-100a question

I have the DTA-100 and it loads a clean 110 volts each channel driven with a 1000 Hz sine wave into my big 8 ohm non-inductive resistor before the resistor starts heating up (about 30 seconds). That's about 37 watts per channel, and I think the power supply holds it back a little. When I was in high skool and lusted for an EICO 30 WPC amp kit that was $150 smackers ( or half as much as I paid for my used '58 Imperial), The DTA would have sent me to the moon. Oh yeah, the technology that's in it didn't exist we we went to the Moon...

Um, you sure about that?

I am sure that I am not sure about it. listened to and been around that amp a lot. I think I will have to go with pknaz, if you can get 18 to 20 watts I think you would have it maxed. I do not think I would want to do that for long.

Re: DTA-100a question

I was questioning the VOLTS.

Yeah- me too. I don't think a 24V/5A PSU will send 110VAC through the outs of an amplifier.
Not happening,
