I'm hoping so. I hate buying stuff I have not heard. I'm more concerned about the amp than the phones, although I have internal pics of it, and it looks well made. It's actually a hybrid amp.

Well, I just ordered one along with my new AKG K701 headphones. I'll let you guys know what I think. I alway wanted to try a hybrid.

Found this really neat tube headphone amp. Is anyone familar with it? Here is a link. http://shop.vacuumtube.com/product/B000L1PXIW/Merchant/VAL-E10-Vacuum-Tube-Headphone-.htm

Hi, I was wondering if you could give me some input to a slight problem I have been having? The other day I still noticed the very slightest kinda hum buzz going on in both of my channels. It can only be heard at all if the amp gains are past half way up. If you were not listening for it most people wouldn't hear it. I noticed it after playing my Nakamichi cd player, and switching over to my Harman Kardon CDR-26. The Nakamichi is dead silent. All I have to do is turn on the H/K and I get the noise! I don't even half to be on the H/K's input, just turn it on. I'm sure this is some kind of ground loop, but I don't want to put any signal degrading isolation transformer on the H/K outputs. Any suggestion? I was thinking of grounding the Chassis directly to the my Crown IC-150's chassis. The connecting cables between the H/K and Ic-150 are quite old, but then again so are the one's between the Nakamichi and the IC-150. This is the only component giving my a noise issue. Everything else is dead quite! I tried moving the H/K's power cord to a different outlet with no improvement. My Ic-150 is connected to a Crown XTI-2000 power amp.

I found the ground loop problem! It was the cable box which goes into my 62" tv then the tv goes to my Crown IC-150. Pull those off the Crown and the buzz and hum are gone. I bought the Rolls he18 hum reducer and hooked it up between the tv out and Crown IC-150 and that took care of the hum in my system and doesn't effect the rest of the system. Sounds great plus I can't get the amp hot enough to run the fans. I'm very happy so far. I have no hum or buzz the amp is very quite. My question is why don't more people buy these pro-amps for home stereo's? This is a very clean powerful amp for $699.00. You would pay at least $1800.00 for half the power in a consumer amp. I'll never look back. I will admit the sound is a bit more analytical the best way I can describe it. I'll never run out of headroom. I have to laugh when I hear people talk about how harsh these pro amps are, I sure don't find them harsh at all.

Just hooked up my Crown Xti-2000 to a Crown IC-150 pre-amp, and I have a lot of hum and some buzz. The IC-150 pre-amp outputs are going the Xti-2000 with an RCA to XLR cable. The hum is ridiculous. how do I solve this? I had and Onkyo M504 hooked up to the system just before I hooked up the Crown and there was no hum at all. Can I run the amp with nothing in the inputs just to see if it's the unbalanced leads going into a balanced inputs causing the problem?

I use to own an H/K twin powered 930 reciever. Great sounding unit!

Is anyone here using a Crown IC-150 pre-amp with any Xti series amp? If so are you having any problems with hum? Does the IC-150 drive the amp ok? Thanks.
