I learned matching headphones and amps correctly was something. I think I fortunately came to the point. Thanks.

Thanks. I may not be able to get the right tubes for X-can v2. Not enough time to look for also. So I prefer a ready-to-hear one. I just read some folks picked Creek OBH or Grado RA-1 for their Senns. They do not match with CD3000? Or alternative choice you make?

I had a chance to try Grace Design 901 for my CD3000. Too good but pricy as well. I just need the quality of its amplifier part less than $300 if possible, since I plan to get a new DA other than Grace Design. Can anyone here advice to choose a good buy?
