Has anyone tried this combo? Trends TA-10 class T + AKG K1000?
I'm looking for a cheap amp for my future K1000, until i get some more money to buy a better amp.

I have a highly modified version based on these mods: http://www.michael.mardis.com/trendamp/mods-1.htm

I must say..it's wonderful. Better than the original T-amp or the Super T-amp I use to own. For me, it's powered by SLAB (Sealed Lead Acid Battery) and driving my speakers. I wish I had K1000 to audition with it. I can only imagine it to be great

"One can use the t-Amp as headphone amp, with caution: first of all, there's no output jack so one has to adapt the speakers posts to a female jack. Secondly, frequency response rises at the highs as the load increases. Tripath claims the output filter should be designed to make the amp linear till 16 ohms. Hence, I'd suggest using extremely low impedance headphones or ask a techinician to modify the output filter settings."

For the k1000, 120 ohm, this could be a problem. However I'm not an expert and it has been done.

The k100o is not a headphone in that respect. It's meant to be driven from the speaker terminals of an amp.

class-D amps can't do treble right. they are too polite. i think you'll like solid state or tubes better.

One of the forum members has a Firestone Audio 'Big Joe' amp and seems to like it for his K1000. It is twice the price of the TA-10 and is also a little more powerful. It may be an alternative if you can afford it.

That's not the point.
Digital amps require an output filter, you have to filter out the high frequency noise out of the output. Since the amps are meant to power speakers, these filters are designed to work driving around a 4 or 8 ohm load. There was a long thread about the potential for damaging the k1000 using a sonic impact to drive it.

To get around this, I put an 8 ohm resistor on the output of my Charlize, when it drives my K1000's. The amp sees a 8 ohm load, so the filter works as designed. The charlize has enough power to drive the resistor, and the k1000's.

The Red Wine Audio Sig30 is a digital amp, using the Tripath chip, and many members of this forum use it with their k1000 without a problem..

So, if i get a "Big Joe" amp, this problem (?) will be eleminated, as Big Joe is not a digital amp?

The Red Wine is a different chipset and highly modified component set, plus it very costly, presumably partially to eliminate the problems of the bog-standard t-amps.

No, Big Joe is not digital.

Never having heard either I cannot personally vouch for them but I assume they work fine with the K1000.

The thing is i need something cheap for k1000, until i get more money to buy a better amp. The Trends TA-10 fits the bill, but now after hearing that it may damage my k1000, i'm not so sure anymore...

This is a potential problem, not a proven one as far as I'm aware. The biggest issue I've heard of with the t-amp is that the K1000 sounds thin and strident with it, but then, there are t-amps and there are t-amps. Not all are created equal as you know. Personally I'd be more tempted by the Big Joe until you can get better. I do have a t-amp that I use with some Staxes at work and I can test drive the K1000 with it on monday.

The Big Joe is twice as expensive...

Right now i would buy the Trends, but only if i am 100% sure it's safe for my headphones.

I'm sure it's fine as there are people here using t-amps, just add the 8 ohm resistor as randytsuch says.
