Reviewers Choice in the October 2023 Part Time Audiophile
They summed with:
"At the price point of the Emerald Physics amp, I can’t really uncover any shortcomings worth mentioning. It’s really just a great amplifier, and I can’t say enough positive things about it. The fact that it effectively drove the super accurate and resolving $25,000 ATC SCM 100 monitors with such great aplomb and enjoyment on my part speaks volumes in itself. Because of its tremendous value and overall superb performance, I’m unabashedly nominating the Emerald Physics 600.2SE amplifier for a Reviewer’s Choice Award. Another win to Underwood Hi-Fi!"

The Emerald Physics EP600.2SE  amplifier has been over one year in the making. This amp has the all the wonderful traits of an exceptionally great vacuum tube amplifier, but with the muscle, authority, and robust grip of one of the most powerful Class D amplifiers ever made.

It was designed to compete with the PS Audio M1200 mono amps that sell for $6998.00 for the pair. We use the same B&O amp module but went with the stereo version to keep the cost down. Both amps use a very good tube input stage but ours can also be bypassed to run all solid state. If you have to have mono amps you can buy 2 of our amps for thousands less than the PS and actively bi-amp your speakers. 600 watts x 4 for only $5000.00 and now $3799.00 delivered for the pair at intro

The 600.2SE uses a single ended Class A tube input preamp stage to drive the legendary IcePower 1200AS2 Amplifier Core. When used in Stereo Mode, this amplifier is capable of delivering 600 watts into 8 ohms per channel, while able to deliver full power into the most demanding speakers. All of this yet remain relaxed and composed, regardless of program material.

The custom Emerald designed HyperSET hybrid valve buffer uses a single Ended Class A topology with a tube constant current source (CCS) for low distortion but while presenting a dominant second harmonic distortion characteristic of the best Single Ended Class A valve preamplifiers. The tubes employed are precision matched E88CC (6922) and impart a slightly warm and smooth sound characteristic to the 1200AS2. For times when you want a more dominate bite to the sound, simply flip the toggle switch to SS (Solid State) to bypass the tube buffer. We believe some will like the “Solid State Jam”, however we continue to think most of you will listen to the EP 600 in the vacuum tube mode. 

The EP 600 is capable of phenomenal dynamics, immense bass grip and agility… while providing massive headroom for the most dynamic passages and crescendos that make up what music has to offer. The 600wpc rating ensures that the “600SE” can power even the most demanding home HiFi speakers.

The HyperSET buffer can accept both balanced (XLR/TRS) and single ended (RCA) inputs via quality rear panel jacks. The HyperSET buffer also has built-in logic circuits to ensure a graceful startup and shutdown sequence that avoids speaker pops. A front panel toggle switch activates a relay that selects either the valve buffer or a bypass for a solid state signal path. A front panel on/off button activates the logic circuitry to slowly power up the valve buffer's filament heaters before the plate high voltage is applied and all of this is done before the IcePower Class D amp is enabled. The activation of the filament heaters illuminates the backlighting on the dual front panel galvanometer needle VU meters which show amplifier output power levels.

The custom CNC machined aluminum chassis has a luxurious satin, bead-blasted surface treatment finish and then black anodized on thick 6 mm thick aluminum plates throughout. Premium solid copper binding posts are used for speaker outputs, Neutrik XLR/TRS balanced input jacks, and premium gold plated RCA jacks are also used. The visual appearance is nothing less than striking. The distinctive diagonally milled cooling slots at the top provide a glimpse of the internal glow of the tube buffer in action.

Distortion of the amplifier in SS mode is 0.002% at 10W into 8ohms at 1kHz. With the valve buffer enabled, the THD is slightly higher (circa 0.005%) but with the glorious sound of a tube amp. Overall dynamic range is 125dB and the noise floor with no inputs is about 40uV rms. The amp measures 17" wide x 13.8" deep x 4.2" high (including feet) and weighs about 15 lbs. It comes with a 3 year warranty.
