if the k1000 has such high requirements compared to other headphones and it often is used with amplifiers used for speakers can i hook up my stereo poweramps to a k1000 safely?

i have a Consonance Cyber 222 and Cyber 800

http://www.operaudio.com/products/cyber800.htm

is it possible to use these to power a pair of k1000s?

if so is there a cable that can be use to hook up the k1000?

Sure ... the K1000s love speaker amps, and they will hook directly to your Cyber 800 mono blocks with the pigtail cables that they come with - no additional cable required, unless you need longer length, then just splice some good speaked wire.

I expect that combination will sound great - what do you have for source(s)?

the speakers are Consonance Eric-Grand floorstanders.

i'm assuming i have to disconnect the speakers when using the k1000s.... is there an elegant solution that exists to switch between the two?

anything i have to worry about with regards to power to the k1000s?

The K1000 was DESIGNED for using power amps, not headphone amps, anyway. The cable that comes with the K1000 is supposed to hook up to speaker binding posts. The only concern with the K1000 and speaker amps is, don't turn the volume up too high. Just like with other speakers. Obviously, this is easier to manage on lower powered amps, but it's not impossible on 100 watt+ either. As to an elegant solution for switching back and forth? I've actually been musing on this myself of late. I think what I'd do is, use the K1000 speaker extension to hook up to the amp itself, and then make a custom speaker cable that has bare wires/spades/bananas on one end to go into the speakers, and then at the other, a 4-pin male XLR plug, just like the K1000. as long as you can find a good way to wind this wire around your listening room, I think that'd be the best solution. Then you could just plug and unplug the K1000 and your speakers in the XLR jack at the end of the K1000's speaker extension. quick and painless.

does the k1000 go to 4 ohm or 8 ohm?

Search the forums for the "K1000 Selector"

thanks for the info, i'll probably DIY..... i can make something much nicer with a DACT CT3 knob for less and have more choices for selecting (up to 5)

might put two 1/4" and a pair of XLRs on the front and two sets of speaker posts on the back

its somewhere between 100 and 200 ohms, depending where in the spectrum you measure

the 8-ohm taps (or better 16!) if you have a transformer output. more volts, less current, its a match made in heaven.

is it ok to hook up other headphones to the power amp too as long as i am careful about volume? like senn hd 650s or grados?

I've had opposite results. My Fisher 400 has taps for 4,8, and 16 ohm, but the K-1000 seems to sing best out of the 4 ohm taps. You lose a little gain, but a 20 watt tube amp has plenty of that for K1K, and you gain a bit of punch at the low end. Increasing voltage at the expense of current can sometimes have a deleterious effect on bass. Low frequencies tend to like amperage.

This may well depend on the particular amp, so each person should probably experiment.

NO. You'll fry a normal headphone if you connect it directly to the outputs of a power amp (for speakers). It's pretty easy to make an attenuating adapter that will allow you to use a power amp to drive headphones. Joe Grado designed a simple one, for which there may be a diagram posted on Head-Fi somewhere. Without an attenuator, your headphones are at serious risk.

do you have a link to a DIY attenuating adapter that will allow use of headphones?

With the Cary that gives the same power (15 watts) to 8 or 4 ohm, the K1000 goes mutch better on 8 ohm.

With the Air Tight (8 + 8 watts) even at 8 ohm and the lowest gain (6 dB feedback)
