Hi Eric and the rest of the gang 😀
I have received the 902 V4 and implemented the most of the tweaks you mentioned on this great forum.
The 902 is fed wireless from my 5G router, and is in turn connected to streamer, to Lyngdorf TDAI1120 streamer/amp, to the input of the optical converter, Stack Audio Regenerator, to the TP link switch…. almost anywhere in my system. It´s either fed by a PowerBank (not recharging) or a Allo Shanti LPSU powered by a Lessloss power cord and a Synergistic fuse inside.
There is sound coming through, but if its to the better my ears say: NO! The female vocalist sounds thin, the guitar also, there is no width and depth, and no low end. And this is only from the track „Dance Me To The End Of Love“ by Madeleine Peyroux. The music is MUCH more engaging, open, deeper and inviting, with many more layers (depth) when I take the 902 out of the quotation.
This exactly happened to 12-15 other tracks that I’ve known for decades, and put to the test.
In a week I might have the Drosselk V3, and will combine that with the 902, but my betts are not on the small 902 as far as as my40+ years experience in HiFI have brought to my listening.
Happy evening everyone 😀
