Swamp - Sorry, haven't heard the 100. If it's dynamics you want, the the FS has it in spades, as does my current DeHavilland UltraVerve. These are my two favorite preamps. Ended up with the UV for its remote capability and use of 6SN7 tubes which I like for preamps.
What can you tell me about First Sound pre-amps?
Only recently have heard about these pre-amps. Are they as good as they are made out to be? Is the least expensive model as good as say a R0land Synergy? I live in Seattle and have never heard of this pre-amp so any information would be GREATLY appreciated. Thanks in advance, Jerry.
