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 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 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. If both RCA and XLR cables are connected simultaneously the auto switching circuit defaults to the XLR balanced input. Unplug the XLR cables to activate the single ended RCA inpits. 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.

EP 600.2SE Power Output Specifications
The EP 600.2SE amplifier has the following output power specifications at 1% THD+N and f=1kHz for 120VAC mains voltage:
- 610 W into 8 ohms
- 750 W into 4 ohms
For 230VAC mains voltage:
- 620 W into 8 ohms
- 770 W into 4 ohms
However, for extremely demanding dynamic musical passages, the EP 600.2SE is capable of 1250W into 4 ohm loads at 1% THD+N into for up to 15 seconds if called upon to do so.
