ArgentPur is adding GaN-FET Monoblocs and DUO dual-mono stereo power amps to its AgPur solid pure silver cable offerings!

These compact amps offer 250w/8ohm (500w/4 ohm) power, using customized Orchard renowned ULTRA balanced modules, powered by a custom 800w SMPS with soft-start and ultra-high frequency switching for extremely low EMI and very high efficiency.

ALL INPUT, OUTPUT and POWER SUPPLY wiring comprises twisted-pair ArgentPur SOLID PURE SILVER in Teflon air-tubes for peerless soundstage detail and holography... the ultimate transparency (WITHOUT brightness!) that both Gallium Nitride and Pure Silver are remowned.

MUNDORF SGO (Silver-Gold-Oil) premium capacitors are also used in the critical signal path filter to provide even better resolution and soundstage realism compared to other GaN-FET and Class D designs. The musicality clearly equals best Class A but with utmost pellucidity to the source... plus the ultra-fast gut-wrenching bass grip Class D provides.

All Input and Output connectors are also silvered, as is the premium solder, providing a COMPLETE SILVER through-path!

Inputs comprise one XLR and one RCA, direct-wired, eliminating any input switching degradation.

NO tube or other input buffers color the purist presentation...thus the proverbial "straight wire with gain."

We recommend use with a favorite preamp and/or reference level DAC for system optimization.

Chassis are solid aluminum, with vibration-absorbing Sorbothane footers and added top and bottom panel damping.

DISCUSSION

"Which version should I get?"

Well, appearance is nearly identical, with the DUO simply +2cm (3/4") larger in all 3 dimensions.

Our preference is to use a separate MONOBLOC near each loudspeaker, linking with very affordable 0.25M AgPur13 cable-jumpers...and preferably with longer AgPur Athene XLR interconnects. This best practice effects a lower total cost, especially if short power cables can be sent from your room's sidewalls. (Note: If long RCAs are required, custom-length SHIELDED AgPur ICs are available for use to control single-ended noise issues.)

But if you already have established, or prefer, a more traditional central rack components geometry using short ICs and longer speaker cables, you'll find the DUO version easier to implement, and requiring only one power cable. This setup may be true also if you use one central power conditioner and prefer not to send long power cables to separate speaker-area monos.
