@ Edorr, Hi, Sorry about the confusion,$20,000 to $50,000 is out of my price reach for digital!,the Boulder 1021 has been out for a long time, I did not know it had volume control?, Thankyou for patiently putting up with me, you are a gentleman indeed,The Ayon 2s is a cd player, it is not red book only player, it plays CDRs but not sacd, I am confused about the Romulus, Do you beleieve it plays more than red book only?, the specs say it plays red book only on the transport, I really do not know what their version of red book is, to me, thats standard cds, nothing else, I would like a player that plays most of todays modern medias, A cd player or a cd/sacd player, this Romulus is a great recommendation!, maybe I should give them a call next week to see if their player can play my cds, CDRs that are recorded really good!, and, of course I have standard cds, The CDrs are dvd a audio and 24/192 cdrs,, My price range can go up to retail 13,000.00, ,like most audiophiles, used is good to, try to save money is always nice, Edorr, My member friends believe your recommendation of the Romulus is more my tast the the Esoteric K-03 in sound, these are the two so far on top of my list amongst others, what do you think of this new esoteric K series sound?,, cheers.
