Slovakia JJ ECC 802 and 803 tubes.

My new Luxman CL38U-SE has these tubes. They give a nice warm detailed sound w/good bass. Never heard of them has anyone used these tubes, What's your opinion. Not looking to change tubes now but down the road any other brands I might try??

^^^ Actually, several months ago I decided to try the Shuguang 12AX7b silver dragon. I purchased two matched sets for line my stage and phono, requesting extra low noise tubes. I have used them quite a bit, but in my preamp/phono stage they are not as pleasant as the Psvane 12AX7-TII or Mullard old stock. Of course the latter are 5 times the price of the silver dragon. They will come in handy as backup. Did I purchase the wrong Shuguang or are you referring to the same 12AX7b?

Thanks

Shuguang 12AX7LS black tubes from Grant Fidelity are superb. Not cheap. Good from the start, they need about 20 hours to sound right and improve up to 50 hours. I think they outshine Telefunkens.

Thanks for your input on Shuguang and Psvane tubes. They were not on my radar. The CL-38 SE is sounding very sweet w/the current tubes but after more break in I'm going to look into these tubes.

I brought the Luxman MQ-38 power amp with integrate function, did anyone compare the difference MQ-38 standalone and CL-38u preamp?
