I've had a Shrimp for only a few weeks and have it paired up with an Ayre V3, a solid state 100 wpc power amp. The combo is quite good. I think the McCormack DNA-1 would make a great mate for the Shrimp. To quote the Manley Shrimp manual... "As a rule, power up your amplifier last, power it down first so it does not amplify any stray noises which could occur upstream from source components powering up or down."
Those of you having experience with Manley Shrimp
I have purchased the Shrimp and am interested in what you are using for power amps. At this point I want to go with a solid state amp, then possibly tubes down the road. A local dealer has a used McCormack DNA-1,comments? But at the moment I am open to suggestions-want to go used-get the best bang for the buck.
