I bought my ER4s and total airhead 1.5v 3 months ago. The sound is great. I am looking to upgrading in the near future. I talked with Headphone and they suggested the Cosmic amp.
Is this the way to go our would it be better to keep my airhead for portable and get the something else like a Little or headroom for my home. I have a Yamaha receiver and a technics cd player for my home entertainment system. While they are okthey are not a top system.
Additionally, the portable cd player can only give so much quality sound. Is the cosmic overkill?
