I am referring to Aigo Z6, as that's what @discord76 is asking. I am not getting M1 anymore.. apologies for the confusion

unfortunately it cannot.. there is no lineout too, so I intend to use headphone out to connect to headphone amp if need.. but if the sound signature is neutral, I will be happy enough.

Thanks for your reply! Really wanted M1, everything almost perfect, from size to design to colour to bluetooth capability, but I guess having no native decoding for DSD is a deal-breaker for me.. Like some in here mentioned, I might as well convert DSD to FLACs myself in PC to save me more...

Any possibility DSD decoding can be made native by development and upgrading of the firmware in the future?

yeah, I too love the blue ethereal glow of the Sylvanians 6L6GCs! compared to GEs and RCAs, the glow on Sylvanians are very mesmerising... will post mine soon after I got my speakers set up!

Sorry Mike, I very much disagree. Personally I am tired of all the beratings on things Made in China (MIC). The expansion and massive industrialisation that country has done has contributed to the world economy positively in some ways more than the bad rep she deserved. I don't deny the fact...

Any 60s, 70s Siemens E88CC you can review and compare too? Would like to hear your views on it as I use DT990pro too.

spacequeen7, you can see more from this page onwards at tubemongerlib for the variations of Siemens E88CC tubes: http://www.tubemongerlib.com/gallery2/v/6922/?g2_page=8   can't really see the presence of the logo from the one you show, seems likely to be from the 80s.. quoted from quartz...

just a heads up, this amp uses 6H8C = 6N8P = 6SN7.. 12AX7 is not a direct replacement for this tube series without a socket converter and mod to the circuit inside..

  great one Mike! I made interconnects myself too, and have tried various connectors.. Neutrik/Rean/Yongsheng are very good and easy to work with.. and if you have the chance, or not sure if you already did, try it with Canare plugs.. they are just amazing. both build and sonic quality alike...

for all the Siemens mention, I am quite surprise so little was being said on the true E88CC version as the 6922 substitutes for T1.. with the time this festive period offers, I guess this tube should really deserve more recognition, especially for those that craves for some premium value in tube...

some tube sales going here at quartz for a good price.. at least better than what I paid for! especially the Siemens...   but since then, is nothing but enjoyable.. hah..

Finally got myself a Siemens e88cc from quartzacoustic a couple weeks back after decided to taste an upgrade for so long. Not quite cheap but oh man, I think "holographic" as a term to describe headphone audio experience can be quite true afterall...

the more these cans are "burned" and used, the better it sounds.. so sweet on the imaging and vocals..   I tried Lorspeaker mention to remove the foam on the earcup just by pinching them off.. I was hopeful the soundstage can be even wider and crispier sounds (as I am actually very happy...

Haven't got a yellow label for tungsram myself, but loving the transparent signature of my red label which is considered industrial grade and seemingly more robust and better sounding..
