Hi, I just bought a used RA1 for my RS1i, but unfortunately it is somehow broken, so I am considering to buy a new amp for my RS1i.
I did some research and currently here are the candidates:
1. Decware CSP2+
2. Mapletree Audio Design Ear+ HD
3. Purity Audio KICAS Caliente
and probably, I am going to buy the senn hd650s or hd800s, or the Audeze LCD2 in the future, so I want the amp also work great with them, please give me some advice, thanks
and btw, what's the difference between the tube amps and solid amps?
