For your consideration is a rarely seen Aeras electrostatic amp. This is the "little" brother to the Kerry built T2 in a much more compact single chassis design with four 6S4A tubes. This amp Is simply unbelievable for the size and price besting anything I have tried except Kerry's T2. I have tried many different electrostats with it including the X9000 and Audeze CRBN but my favorite by a margin are the Stax 007 MK2.9 (latest version which I will have available after this sells). It is a truly unstoppable combination and not much of a surprise as most of these amps were designed using the original 007. I am happy to answer any questions and have linked to the Eksonic website with all the specs. I have had it for about 18 months and used it very little. Condition is near mint (I hate to say perfect but I could not find a mark on it and I am very picky). This is an earlier production version with slightly different heatsink venting and spacing well as the T2 volume knob which I think looks much better. There is no performance difference. I will add that Kerry's designs are built like nothing else, they have top tier fit and finish and look the part of the price that you are paying. Too many reference headphone products look like exactly what they are, built in someone's garage or kitchen and that is not the case with Eksonic. It is a real product but like the T2, has a waiting list.



It comes with 6 unused and matched NOS RCA tubes from Andy at Vintage Tube Services, the original box, and now power cord (if you have this amp, you shouldn't be using a cheap AC cord). Extras that are open for discussion are a pair of new Cardas CGA input adapters to allow use of RCAs without degradation ($250 retail), and my Stax 007 Mk2.9 bought new about 18 months ago with very little use and all packing.

Can it be switched to European voltages (230/240V)? There seems to be a switch on the backside...

I haven't been able to find much on where this sits on the electrostat "warmth/tubiness" scale: is this going to be closer to the BHSE/KGST end or the Megatron/Novem end?

It's a fairly tuneable amp - with the tubes pictured, it's fairly neutral. The RCAs that come with it add warmth. Some of that is going to come from your earstats as well - x9000 are somewhat cold (with some bass reach but not as warm as say the 007's). ShangJr's are pretty neutral with a touch more kick. None of them are going to give you the warmth of a tube amp with dynamic drivers (or some planars, for that matter), but that's not really the point, either. Hope that helps.

The megatron is the most neutral of the amps listed

BHSE/KGST/Aeras/T2 use a mosfet which adds coloration , aka "warmth" but ultimately they are hybrid
Novem is intentionally colored tube amp (neither powerful nor neutral, but works with x9k and 009 signature)

If I didn't just get a Blue Hawaii two weeks ago I might just buy this asap

Do you know what the voltage of the power supply is and if it's like 15 ma?
