Pench....I like the added sig entry....that is a clear indicator of intention and should go a long way towards warding off any further unfounded accusations....

I like it.

Peete.

Thank you sir. I'm very happy with my cans and the amp. Thanks to all the Head-fiers who were patient with me. Now that I have a good assortment of high quality music, I'm looking forward to trying SS amps, and the MK V looks juicy.

Thanks PP!!

Please copy it for your own use too. I know your intentions are like mine, so it would be fitting and proper!! None believers can k..., well, you know!

Anyone who has experience with AD2000's connected to this tempting amp, would you be kind enough to post comments?

Now that I have a new set of ad2000's i can't help but to think of the possible sound it could produce. I see potential, but i'm not yet totally happy with them.

Thank you!

I do own the amplifier, if I remember correctly the ad2000 are low impedance headphones and I am pretty certain you will get some hiss. I have Grado's (which are 32 ohm of impedance) and they are certainly not quiet with this amp, I think the headphones you own are similar "ohmage". It hissed to a point I decided to get a impedance adapter to fix the hissing.

Good point Grey. I am thinking about picking one of these up too for my HD650.

Thanks. I don't mind a small hiss. My current and relatively new Little Dot I+ is great with grados (low impedance), but just doesn't work with my ad2000's so well. Though now sounding a lot better after some burn-in.

Just fishing for those positive impressions of their possible symbiosis. (like how well ad2000 and gilmore lite match!) ..

Your Senn won't be any problem since they are high impedance (300 ohm) they will be dead quiet.

EDIT: The amp was developped and tested with Senn's!

Since I'm a more of a lurker here than a poster, my post count doesn't let me post for sale ads. Nonetheless, my MKV is for sale. PM for details.

I thought the HD650 sounded good on the MKV until I tried them on the Woo...I also had the D2000's and thought they sounded great on the MKV, and I had no hiss. They both sounded similar on the MKV, actually. The Woo/HD650 combo completely crushed the Woo/D2000 combo, so...I sold the MKV and the D2000... That said, I DO really like the D2000 and MKV as a pairing...they sound great together. Tubes suit the 650s, and solid state is great with the D2000. If you have an electrically clean environment that's relatively interference-free, and use properly shielded (or twisted) cabling, you shouldn't have low impedance hiss issues. I never did, but YMMV...

Hi,
I've got a LD MKV and it is so clean, I can listen to HD 650's at 1:00 or so, and on some voice have pushed it around to 3-4:00 for a short period.

Huh?

You talkin' to me?

Well speak up Son!

Will there be good synergy with the Beyerdynamic DT770 Pro 250ohms or the DT990 Pro 250ohms?

Mine works very well with my 300 OHM HD650's and my 25 ohm Denon's.

Hello,
How do you get the Box open on this Gadget? I want to look around!

The internals are on three boards: The front board is the electronics and the rear two are the transformers. There's a generous amount of wire connecting everything so that you could just pull out, say, the front boards to change the opamps.

To change the opamps, you first remove the volume knob and the nut on the volume pot, then the two hex screws holding on the front panel. Then you have to turn it over and remove the 9 front-most screws. It's easiest to do the front-center one last, as the board will then drop, which you can catch. Then you carefully turn it over again and slide it out. If it doesn't slide out because the wires catch, you have to remove the rear panel and push the wires from it through, as they tend to get caught. Note that the voltage regulators are on aluminium blocks, held by two screws each. On the bottom of them they seem to have lots of thermal grease, so things can get a bit messy.

If you're thinking of (tediously) opamp rolling, the results will be the same as in the Zero DAC, roughly: LT1364: sounds rather "hard" and not musical, as well as running very hot. LM4562: Very "fun" sound with boosted bass and treble. I didn't have OPA627s to try unfortunately. I did manage to fit HDAMs in mine, with wires, leaving them to sit on top of the voltage regulators with a piece of plastic in between. There wasn't much difference between Earth, Sun and Moon in the MKV though. Securing the HDAMs in the unit though I didn't find a satisfactory solution for.
