Christmas special..
The Emmeline, F-35 Lightning, is the SMALLEST fully BALANCED, input to output portable amp we have designed. It has a balanced and a single ended inputs, RSA 4 pins connector and 3.5 single ended.
F-35 is capable to convert the single ended signal to a balanced signal so you will always listen to balanced output no matter what input is used.
The amp's dimensions are 3 X 1.75 X .75 inches. It packes power that drives all high impedance phones and most of planer phones as it swings 16.8 volts p-p at one amp of current. It has low gain of 3, medium gain of 11 and high gain of 21. It comes with Lithium Ion battery and charger.
We supply three cables with it that gives you the flexibility of using different input sources and outputs for headphones.The sound is dynamic, smooth and sweet.
The package is $625.00 plus shipping.

This is what an owner of B-21 Raider posted...
Guys,
Jump into the upgrade asap!
It is totally worth it. I got my new Op Amps on Friday. The update took me from start removing the first screw from the top cover to tight up the last one no more than 10 minutes. Super easy!

I have been burning in the new Op Amps since Friday night and today I did my first critical listening using the ES-2a.

The sound is very detailed and 3D but at the same time with a touch of warmth and naturalness that makes it very organic and beautiful.

I was listening to Sting’s All This Time live album, Diana Krall Live in Paris and Chris Jones Roadhouses & Automobiles. The texture of the voices was perfectly real and the level of micro details it was spooky but without being analytical at the same time.

I always thought the B-21 was a good step up from my A-10 but this upgrade takes it to a totally new level!

Bravo Ray!!! 👏🏻👏🏻👏🏻👏🏻
