what are the Best Direct to amps Digital Players ?

Hi everyone, I Thank everybody here, I am still looking for more answers, look forward to your post, Happy listening.

Is there eany tube players with its on volume built into the player?

Yes, the Aesthetix Pandora. Analog tube VC.

@ Edorr, Hi, I hope I am not a burden, I would like to ask, Have you listened to this player, can you describe some of the sound attributes that are good and bad?, thankyou.

Most of the posts I have browsed through indicate the K-01 is a 10%-20% improvement over the K-03. If that is true then I can say with relative confidence that picking up a K-03 w/ BelCanto's RefLink USB Converter ($1,500) gets you very close to the performance of the K-01. That is if you plan to use the K-03 for Computer Audio playback. I conducted an A/B comparison using the RefLink and without (Using the Audioquest Carbon USB's). There is a noticeable difference in soundstaging, transients, and dynamic range when using the RefLink vs running straight from the headless Mac Mini to the Async USB input on the K-03. It simply removed additional digital artifact then without. In fact, I would recommend getting a high quality USB converter for anyone who has a K-03 or K-01. Finding a local dealer that can provide a demo unit would be a sound choice to determine if you experience the additional improvement I have experienced.
