Need advice on Unico 12AU7 tube rolling

Dear all,

I am using a Unico CD Player which uses 2 X 12AU7 (ECC82/5814) tubes. Somehow the stock tubes seem to be quite dull and lifeless. I wanted to try changing the tubes. I prefer to have more detailed sound with more clarity. Can anyone please advise on :

- What type of tubes can I try to get more lively and detailed sound ?

- Also, how can I change the tubes in Unico CD player (any procedure to follow ?). I am totally new to tubes.

- Can I get some links to where I can find some beginner info/guidance on tube rolling ?

I will highly appreciate any experiences with tube rolling with any Unico Amp/Pre or CD since most of the Unico products are using the same ECC82 tubes.

Kindly advise.

Thanks in advance.

I also own this cd player. If you want detail and clarity I highly recommend Radiotechnique and RFT tubes. In terms of transparency and detail I haven't found a better tube than the Radiotechnique in my system. It may sound a little lean in your system though depending on your other components. If you want a little more body to the sound with most of the transparency of the RT & RFT then try a pair of Amperex Bugle Boys. Have fun, this player is very responsive to tube rolling.

Thanks a lot for all your nice inputs. This motivates me to do some tube rolling. Will try Radiotechnique, RFT, Amperex Bugle Boys, Brimar or Telefunken after doing some more reading. Good to know that the player responds to tube changes.

Also are there any recommendations for more authentic and popular tube sources which are reliable ?

Thanks in advance
