Thanks for your thoughts.
Is there really much difference between the Uber Bifrost and if I upgraded to the 4490? I suppose I could go clear to the Multibit, but sending equipment out of the country I live in is very expensive and difficult. So, sending in a card for $70 or whatever, would be far preferable. Can't see to find out much about this upgrade. What difference should I hear?
Also, I'm not at all able to install it, but I have an electrician who can if it is not really hard. Is it a pretty easy install?
I did ask about tubes. They recommended these: The 6n6p, 6n30p and 5814 black plate.
Any thoughts about them?
YMMV on the difference you hear between the Uber and 4490. Many people are DAC deaf and really don't hear a difference at all. If that's you, consider yourself lucky.
For me, the difference was significant. There is more refinement and control...less congested may be the best descriptor. Completely worth the $70 for me, especially after hearing the Bimby. The Bimby is a fantastic DAC, but if you're talking about diminishing returns, then this is a shining example. It can be argued that the Bimby has better detail retrieval, but the differences really come down to personal preference. A touch more warmth (Bimby) or a touch more energy and sparkle (4490). Really, though, the difference between the two is very small...and the price difference...not so small. 4490, hands down.
As others said, the upgrade is pretty straightforward and well outlined in the Uber thread. If you go down that road and need tips, then by all means let me know and I can share my experience.
As for the tubes, I run a 6N6P with my HE-500 and LOVE it. It's a darker/smokier tube, but it does so without losing detail or sounding smeared. It didn't pair so well with the HD650, though...made it seem a bit dead. I'm afraid I can't offer much of a pairing suggestion with the Audeze phones.
I also have a 6DJ8 (Amperex) that I find to be an excellent all rounder that sounds good with just about anything.
