I noticed hum on my WA-22 a week ago especially when using sensitive headphones. It was a constant hum regardless what volume I put. It doesn't bother me when I listen to music, just in between tracks or when no music was playing. Eventually I found out it was caused by my GEC 6as7g tubes. Once...

Got it. Thanks!

I am now using these two combos the most 1. Chatham 5998/ tungsol 6AS7G + GEC 5u4g + kenrad vt231 2. GEC 6as7g + Treasure Globe 6SN7-SE + Sophia Aqua II 274B

Can anyone tell me what the date code 722 mean? My guess is week 22 of 1967

LCD5 is my daily driver along with Niimbus/WA22. I especially like LCD5 plus WA22. I think WA23 and 33 would be even better, but wa22 wins the price.

Very smooth trade even though we had to do it across the border. Very trustworthy headfi member. I would not hesitate to do business in future.

I prefer a cash sale at the moment, but feel free to send your offers.

The most engaging version from yggy line, No need for more introduction. Fully functional and in great cosmetic condition. My price includes PayPal fee and shipping. 4% off if you pay via FF.

Wow, you bought a Niimbus while having HA200?

This makes more sense to me, but ppl can have different preferences at some points

I am comparing yggy+og and yggy og via an XLR A/B switch. They were both fed via Unison USB by Roon Nucleus+, and output to the same amp and headphones. I feel the new version has better details and sounds smoother. I know they are suppose to sound the same techically, so was it just my illusion...

This is real, or just rumor?

I bought this used with some paint chips and minor scratches. I installed a Samsung 2TB EVO860 SSD (cost me $300) and the unit served me flawlessly for 2 years without a single error. The unit is in perfect working condition if you don't mind some minor cosmetic defects. My price includes...

They shouldn't make significant difference in sound, but I support the Canadian one. Every product made in Canada that I bought so far never gave an issue.

RME clearly stated somewhere that any "better" PSUs will not improve sound quality of their DACs at all. They even said in their forum that their new LPS were not going to improve SQ for adi-2 lines. They are only for who want them. I'm a bit confused the point of their LPS. Maybe they have...
