| Gustard R26 vs hi end streamer DACs use electrolytic capacitors in power supply that need a very long burn in. Amplifiers need less time. In my experience with Chord and SMSL DACs it was 3 weeks plugged in AC. And height frequencies finally improved at the end of this period. | |
| Gustard R26 vs hi end streamer Hi @lanx0003 , For any DAC I had 100hour of break-in - it is nothing! For example I run a new Chord Qutest around 200 hours and was sure it plays on 90% of it potential. Then I didn’t listen to it for 2 weeks. But is was plugged in to AC without... | |
| Gustard R26 vs hi end streamer Hi @sls883 , So far I found a solution to plug and unplug USB cable into ET3 (I have easy access to do it). It is not a big problem for me because I listen to PCM (CDs and files) 95% of the time. In one month I will receive my old SMSL do300ex (... | |
| Gustard R26 vs hi end streamer Hi @sls883 Yes, coaxial works when I unplug USB. The problem is only when both cables are plugged. I need both these cables because PCM sound better with Coaxial cable, but I need USB cable for playing DSD files. | |
| Gustard R26 vs hi end streamer I got my Gustard R26 today. I connected it to my Shanling ET3 transport by USB and Coaxial cables. When selecting USB input it works, but when I select Coaxial input I can hear music playing for a second and after it is silent. But when I unplug ... | |
| Gustard R26 vs hi end streamer I read here on this forum that r2r dacs need a very long break in. But my experience shows that it is true for sigma delta dacs too. Qutest was playing 200 hours but the sound was improved after it was plugged in AC during 3 weeks. The same stor... | |
| Gustard R26 vs hi end streamer I also ordered Gustard R26. I will probably get in next week. I had Chord Qutest for 5 years and now I have an SMSL DO300EX (AK4499 chip). I also have an old Cary cd-303/100 CD player on a Burr-Brown PCM1704u chip. I mostly listen to jazz and c... | |
| Seeking a Warm 12AX7 Tube for Preamp What is wrong with Psvane 12ax7. I use it in my phono stage instead of Sylvania 5751 than I used for many year. And I don't feel that Psvane is inferiors to this great 12ax7. | |

| 300b lovers Another thing that drove me mad, my SET sounded too analytical and sterile. It took me 6 month to find the source of this issue. It was a Vishay Z-foil resistor in input stage 6sn7 cathode. When I changed it to a Shinkoh 2W resistor all this so... | |
| 300b lovers Diar @lynn_olson Thanks for the informative answer. I used a 6f6 driver in my single-ended amplifier, which I have been improving for many years. For some reason, Shindo used this tube in the driver of his 300V amplifier, and the person who mad... | |
| 300b lovers Hi @lynn_olson @donsachs When did you play with the driver tube to your amplifier? Which tubes did you try except 6v6 and kt88? Did you try 5881, KT66, 6L6, EL34? If yes can you compare the sound of these drivers? | |
| Best "Bang for the Buck" you have owned? SMSL do300ex DAC. Lenco l78 turntable. Croft preamplifier with phonostage. | |
| Six DAC Comparison Hi @facten I’m not @classicrockfan but I have a similar experience. I had in my system Chord Qutest for many years. This May I bought an SMSL DO300EX built on the AKM 4499 chip. This DAC looks like a toy relatively to Hi End DAC but it sounds b... | |
| 300b lovers Hi @lynn_olson I upgraded my 300b SET amplifier. I replaced 6f6g Torvac driver tube to 6v6 Psvane. 6f6 worked with idle current 26ma. 6v6 with the same cathode resistors gave 24ma. I changed cathode resistor to get 29ma. In result much better ba... |
