Atma-Sphere S30 MKII

The signal paths of the two amps are the same. The Merlins appreciate the extra power though.

BTW the ASOG site got shut down in October of 2004. A good portion of it is archived on the OTL Asylum at audioasylum.com

What is the proper method for removing output tubes to lower the power? Any downside to doing this? Rising output impedance?

in the S-30 you can just pull power tubes. My speakers work fine with 3 per channel, but they are about 97 db 1 watt/1 meter. The output impedance does get raised so with certain speakers you might introduce a coloration.

Thanks Ralph. I think I'm going to use the M60s as is and just enjoy the music. To my ears your amps and Merlin VSMs are about as good as it gets. Looking forward to the 3.1 upgrade.

how would the s30 work with a 16 ohm load?
