Absolute top tier DAC for standard res Redbook CD

Totally unrelated question for you tube guys;

I need some help. I'm in the process of adding some audiophile related decor accessories to my almost complete listening room. I'd love a bunch of no longer functioning, used up output tubes:

6C33C, 300B, 845, PX-25, KT-66/88, giant Kronzilla tubes, etc.

I'm glad to pay something reasonable plus shipping.

If anyone has any, or knows where I can get them please PM me.

Sorry to hijack my own thread. Lol.

Now back to dac's and servers.

4orreal - I cannot list them here. I do business with some of these guys. Basically all PC-based servers I have heard and most Linux ones.

Thanks,
Steve N.

Hi,

I just want to add my observation of USB cable which may be benefit for all.

I use YFS USB cable from my Mac Mini year 2012 to Offramp 5 and SPDIF cable from Offramp 5 to Audio Note DAC mod to level 4.1

The sound quality of YFS data only-Reference USB cable is much better than Oyaide Continental 5s Silver USB cable in my system.

Because Audiophile USB cable is more heavy than stock USB cable. The heavy weight of USB cable makes too much force or stress on contact point in USB socket and has worst affect to sound quality. Then I do hanging the USB cable so that there is less or normal force or stress to contact point in USB socket. The sound quality improves a lot in term of transparency, focus, halo-graphic and much better clear vivid mid range sound.

This is my observation. Please try and report back of your result. It is an big improvement without any payment.

Steve,
I can undterstand that. Thanks.

Matt: do search on ebay for "display tubes"

AL,

I use modded SqBox Duet, MacMini, MB Air, CD transports, SACD player, SqBox Touch.

I will likely get an Aries and mod that heavily, and perhaps a Caps server to do HQP DSD upsampling.
