something special for low-ohm headphones
Posted by NEBill from NE on 2011-12-10Posted on Grado RA1-AC
Recommend Product: Yes
Pros: sound quality is musical and open
Cons: expensive, but a bit clunky
This version won't drive your Senn HD600; you will have to look elsewhere. But, if you have Grados, it will open up the sound, so that it's airy and clear. I believe that there's something special about the chip inside. In fact, I think this unit makes a great little pre-amp, too. Different strokes for different folks, but there's a reason why this amp, in all it's various incarnations, keeps selling year after year and continues on best-of lists. That's because it involves the listener and pulls them into the music. Whether that's worth it depends on you as a listener and how you handle money.

Nice Wooden Box

Recommend Product: No
Pros: Nice Wooden box
Cons: $10 worth of hardware, huge wall wart
I bought this to drive my old Sennheiser HD600's. It weighs about 1/4 ounce and has one of the largest, ugliest wall warts I've ever seen. When I opened it, I was dumfounded. The circuitry consisted of one opamp sealed in hot glue, a variable potentiometer for volume control, a switch, and an LED. That's it. I paid over $400 for this? The mahogany box was easily the most expensive part. I don't know, maybe that opamp was some super secret expensive component. You need a special hex-wrench to open this amp and I'm betting Grado hopes no one like me ever does. I'm not familiar with their headphones as they were always uncomfortable to me. I sure hope Grado puts more thought into their cartridges and headphones than they did in this amp. Bottom line: Keep looking. The Headroom Micro Amp is twice what this unit is and it's cheaper.
