.......Is there any problem running the K1000 through a high powered class D digital amp, with a preamp of course....am talking around 350 to 400 watts a channel into 8 ohms for this amp. It's the older eAR 1 from Acoustic Reality in Denmark. Thanks, John

I have been running my K1000s with a Hypex UCD 180AD (180w into 8 ohms) class D amp for many months. It sounds wonderful. The amount of detail is staggering. It is also dynamic and has a good tonal balance.

Last week I received a new SinglePower Extreme and am now trying out various tubes in it as it breaks in. I find that I did not realize how much I missed the romance that tubes bring to listening.

I think that the K1000s are made to be driven by a regular amp and really need one to shine. The Extreme seems to be an exception. I doubt that it puts out 5w but it sounds great...

There's a danger in running any speaker off too much power, sure. But in headphones you would be worrying about your ears catching on fire before this happens.

Because K-1000's are 600 ohm headphones, they wont pull gobs of power out from a hi-fi amp. So it's not like you need to worry about keeping the volume knob a notch above 0, but just play within reasonable volume levels.

Thanks for the replies....This older eAR 1 class D digital amp was one of the first ones out there...you may have seen it...it's in the shape of a triangle and is made out of stainless steel..lol.....sounds really good on speakers, so I suspect it will sound great with the K1000. .I was concerned it was too much power, but I guess with the pre-amp in there, all I have to worry about is making it too loud for my ears.

I also have a vintage McIntosh MC-240 tube amp I want to try...that's 40 watts a channel...has anyone tried that combo? ..that does not need a pre-amp, as it has separate left and right volume pots.

Looking forward to getting these K1000's...never heard them before. I have had nothing but Stax for the last 15 years. Now I will be in the K1000 club!

The K1000's are 120 ohm headphones with a very low 74db sensitivity for 1mw input. While K1000's dont have excessive current demands in comparison to speakers .... they do need lots of voltage swing. You will see there need for power is 1000 mw max = 1 watt. That is why an amp like the Extreme can drive them with authority .... the Extreme can supply 1500-2000 mw and being tubed the voltage swings are easily accomplished.
