Go with a modded Stax amp and a Koss to Stax adapter from Mjolnir Audio. The ESP95X really come alive with more power and the Sr006t modded amp I have also works great with my SR007.

Crosszone CZ-1. Never heard of them before the show and I should have listened to them through an amp. I would like some more time with them and my own stack but I don't know if I want to spend $2500 for an experiment. Audeze Carbn. Stax SR-X9000. Spirit Torino Pulsar. ZMF Caldera. Grand...

First public candid of me since 2019, to boot. With the caveat that I was feeling hyper critical and you can never get enough time with headphones at CanJam: The HE-1 was great but not mind-blowing in the way I expected. I was in the first group to demo and everything was just perfect. Not in...

The amp didn't ship with the issue a year ago so I assume the caps and resistors were fine at the time. The issue likely isn't so common that those parts should always be replaced when modifying the amps listed. He didn't explain why it was only in the left channel, but by the time I sent it out...

Mjolnir Audio SRM-006tA with a CCS mod. A few months ago I was getting static-like noise in the left channel that increased with volume and evolved into a noticeable imbalance. From spritzer: "The HV- line wasn’t working and it was a failed resistor that connects the two caps there. I’ve seen...

I had to send my amp out to Iceland to be repaired, but after a month and a lot of money in shipping it's back in good working order. The SR-007 are really something special and how I imagine Audeze would turn an estat in the early 2010s. I've read they scale well with more power, but for the...

Birgir has modded/refurbished Stax amps for considerably less. I bought an 006tA from him last year for $1400.

The topology has been discussed elsewhere and it's thought to be very similar or identical to the Koss Energizer. 2000ppv is astronomical and I would be wary of taking that figure at face value.

Pretty sure my electrostatic amp is the issue now. Static noise which varies with the volume knob in the left channel, left is much quieter than the right. Only happens when the AGD is connected to the estat amp, and it's worse in balanced mode. I took a meter to my AGD amp and it measured...

spritzer is always selling refurbished/upgraded Stax amps. I use an SRM-006t and it pairs exceptionally well with the SR-007.

By his own admission he's very brash and has high standards. but his criticism of the cans themselves isn't scathing. When we're spending close to 5 figures on audio gear it should make us angry when sellers are uninformed or put out a subpar product. E.g., the Edition 10.

When my Mjolnir SRM-006t is connected to my AGD D27 via balanced XLR, the left channel is much quieter than the right, and there's a beeping/static noise in that ear which responds to volume control. This happens to both my 950X and SR-007. The D27 is connected to my PC via USB, and does not...

Electrostatics are lightning fast and have much more natural imaging and presentation than regular dynamics. They require dedicated amplification not compatible with regular headphones and are much more sensitive to dust and moisture. Bass quantity is often times less than dynamics. The barrier...

Update: The left channel in my SR-007 is much quieter than the right and the static noise gets louder based on the volume knob. Would blowing air across it fix it at this point? It's only been a few days and this issue has already killed my excitement for them. Edit: It was the left balanced...
