STAX SRM-700S Electrostatic Headphone Amplifier

Very good, not my favorite match for CRBN-2

I’ve been trying various amplifiers for my Audeze CRBN II headphone ever since I got them (I had the CRBN upgraded. ) This is a relatively small amp, you can use it on a desktop, very quiet and clean. It does not get much bass out of this headphone, though. The balance is bright to me as a result. It ultra clear, detailed, and enjoyable and with a small bass boost through gentle EQ brings out more of what the CRBN II is capable of delivering. I have never heard the amp with Staxx own headphones.

The SRM-700S is the best reasonably sized energizer STAX has ever made, in my opinion. With the true balanced XLR inputs, there is a massive amount of power on tap for every headphone in my estat collection, much more than even the SRM-400S. The device feels premium, well-made, and quite solid. The knob feels great. It only gets hot in the front top half of the chassis where the vent is, otherwise it's quite cool and efficient. Solid-state circuitry means clarity and noise floor is unsurpassed by tube/valve amp offerings. It fits on my desk, which is fantastic. Detail retrieval and dynamics on my SR-009S earspeakers are superb with this energizer. Overall, well worth what I paid for it, as it powers my other estats with ease as well. A fine addition to any electrostatic headphone collector's setup!

Good to do business with

When purchasing quality gear, it's always reassuring to know that you're dealing with people that really know the electronics they sell inside and out. That's been my experience with Headamp, and I'd be happy to recommend them.
