@turcoda the DAC is Amazing... Get your laptop squared away (preferably ditch your laptop entirely).
@lordmelton is 100% right with his troubleshooting advice. Man knows his stuff.
Don't get discouraged the 005 is well worth the 3k price (double or triple IMO).
Quick hip shot from the Tambaqui vs 005 slow roll testing. Center image Tambaqui really shines. I'm literally pausing tracks, going back, and am just like "man I never heard the vocals so dead center before".
Really enjoying the Tambaqui, 3k vs 13k enjoying the Tambaqui... Well... Ugh... Probably not so far...
I've done a TON of headphone listening with both the 005 and Tambaqui and again, Tambaqui (with HPA4, and 005 for that matter) definitely ups my headphones to the clarity, channel separation and low frequency bass speed/control of the my reference Stellia's. literally my Z1R's sound 90% like my Stellia's in the domains of the high frequency and low frequency. Stellia's have unfortunately obnoxious separation now with the Tambaqui and somewhat fatiguing detail (but never had the Z1R's sound staging to begin with). So in my own personal case that's a potential $1,700 cost savings on cans. People will probably disagree, but just my hot take.
So Tambaqui has right out of the gates (in my opinion equivocated to $$$)
Roon Endpoint ($500)
Better Headphone listening ($1000) with the multiple amps (SPL, Benchmark, RME, Sony Tazy I've tried)
Excellent app ($250)
Size and aesthetic ($500)
So gateway Tambaqui price is now creeping ever so slightly down to maybe 9-11k mark, but still way up from the 3k 005.
I'll again keep dumping "as I go" impressions here, along with a big deep dive review of them both.
