$1000.00 don't buy first-rate player new.(I have not heard Musical Fidelity from audioadvisor.com).I have dealt with this company many times without any problem.If you call them talk to Ken or Chris.They also have demo.Parasound 2000 Ultra.This one I heard in my system.It was in completely different class than my Luxman 355(about the same or a bit better performance than your Marantz).But my unit (Parasound) was damaged in shippment and at that time they did not have a replacement.Later I bought from them CEC 5100Z new which is similar to the Parasound but,I think,is even better.Another alternative is to find used excellent converter and later replace your 63SE(I suggest CEC 5100,audioadvisor.com have it now for $800.00 new).I would go with Timbre DAC or,perhaps,Classe.
