| Does it worth a upgrade to Dolby Atmos? Thank you maxwave. C-J is single ended input. I used to have Theta Dreadnought which is fully balanced. I found it is a overkill in my set up. I agree that It is better than C-J. But I am happy with C-J because it matches color with other C-Js in... | |
| Thinking about getting a R2R DAC I am looking for a DAC for a while too. R2R came to my mind. Orchid, Audio Mirror and Lampizator, etc. I considered Lampi first, then Lampi changed from R2R to DS and Amber III has very good review. Even their flagship has DS chip. I am confused, ... | |

| SET amplifier recommendation Thank you for all comments. I also have some concern about sensitivity of 805. I do ask Israel regarding the sensitivity (both B&W 805 and Polk Audio LSi7). His answer is OK. if the speaker is an issue, i need a pair of high sensitivity ones. ... | |

| 6DJ8 measurement error on Hickok 600A Thank you for all your replies. The problem is solved by replacing 600A with 539B. All the readings on 539B are reasonable and repeatable. I really like 539B a lot. it is much better than 600A. I think 600A may not have the high current capability... | |
| Tube phono preamp for CJ LS2 It seems no one selles CJ Premier15. It must be very good. | |
| Turntable bearing noise Thank you for all the replies. The noise is gone after hours and hours running. | |
