Ars-Sonum And External Preamps...

Hi Rich,

Has Ricardo mentioned to you what the Wattage will be.  Also, will the amp be capable of driving lower impedance loads then the limits set forth in the Filarmonia Manual. What output tubes?.  Will the amp have a selection for triode operation.  Pure class A or ??. X-former taps for 4 and 8 ohm loads?

Thnx
Brad

The Armonia power amp is 30W/ch. Like the Filarmonia integrateds,  the output transformer has a single output (no various output impedance taps as Ricardo feels he gets better sound when he builds/winds/optimizes the transformer for one output impedance which is around 6 ohms). The Armonia like the Filarmonia operates in Class A up to around the last few watts of power (I can get the exact numbers from Ars Sonum if that is important to you). The optimized output transformers in the Armonia power amp though are a single output  “6 ohm” output design, have a more efficient (or maybe elaborate is a better way to say it) design with a lower effective source impedance. Max power output is greater than the Filarmonia integrated (30W vs 28W for the Filarmonia SM) and the ability to drive lower impedance (4 ohm) loads is better than the Filarmonia integrated amp.

All Ars Sonum amps are push pull class A.... Not a traditional Ultralinear design. Since already running almost completely in class A, no need for triode operation IMO (I’m not even sure that given the nature of the design that it could triode/pentode switching could be added).

Interesting. Thanks for the info
