Has anyone compared these two amps? If The META could run on battery power,what would be the battery life?
The meta42 can be made alot smaller than the cosmic which is a huge advantage if you're looking for portability. |
I strongly believe the meta42 opamp -> buffer multiloop configuration is superior to whatever circuit the Cosmic uses. (I've never read anywhere exactly what the Headroom amps are, opamp -> discrete, or opamp -> opamp ???). |
Originally posted by thomas The cosmic is a very professional design (ie done by real engineers), with discrete push-pull output stage, and OPA627 opamps feeding it... Meta is also a nice design, and tweeked for maximum performance... But at this level its more about personal preference than "strongly superior" |
You also will not get some of the features of the Cosmic, crossfeed and variable gain. |
Sijosae's work is beautiful as always, but it is not a META42. The circuit is not the same, it is missing the FET cascode current sources. |
