Without a shred of doubt in my system with my upgraded Denafrip Tplus dac albeit both are not analog since digitally processed ... it does not hurt that the Bel Canto is 24bit 192khz vs 16bit 96khz of the T1000.
I may not wish to share this if I had not managed to have the 2nd unit after 2 yr search globally as spare for my 24/7 listening to local fm stations .. lol !
I listen only intermittently to the hi res Qobuz, full flac internet stations via antipodes or even more rare occasional cd via Denafrips Avator transport.

My Marantz 10B is doing very well thanks to Richard Modafferi as he messaged me this morning about the restoration he performed. I think I picked the right person.
"Hello,
Restoration successful. Tuner going back to Audio Classics today for glass replacement.
Tuner blew fuse because electrolytic capacitors had "deformed" after a long time with tuner not turned on. Capacitors successfully reformed and fuse replaced.
Tuner works (poorly needing alignment) but has no stereo. Problem traced to bad 38Khz transformer in MPX circuit. Open 1/2 secondary winding. Transformer
potted in epoxy and thus repair not possible, I have restored 187 Marantz 10B tuners since 1990 for Audio Classics. This one, number 188, is the first one I have seen with a bad 38Khz transformer! There are no available replacements for this part, and RM had to resort to a "fix" using a 38Khz transformer from McIntosh MR78,
my design. I was able to successfully install the McIntosh part into this 10B, modifying the Marantz circuit to use the McIntosh circuit which is my design. It works! 45dB separation!
Performed other necessary repairs and updates as needed. Audio Classics will deal with broken scope knob, either replacing it, or as I did, cementing knob to
shaft with Duco cement, which works. Audio Classics will have to remove knob and re-cement it for glass replacement.
10B works beautifully and looks nearly new after cleaning. Photo attached shows MR78 38Khz transformer in Marantz 10B chassis.
Rich Modafferi."
Now what are the chances of me purchasing a used 10B and the unit has a fault that is extremely rare for a 10B and sending the unit to the man that has "the part" and the knowledge to "fix" it.
I guess I was lucky. Btw Mac tuners do have a history of problems with these transformers.
Only two tuners left to restore in my collection....a MR71 and that goes to RM in 2 weeks and a Mac MR66
Richard sent me a photo of the "fix" for the bad 38Khz transformer.
And wow 188 Marantz 10B's I think he could fix one blind folded.
P.S. I forgot to mention I have seen 10B separation numbers from 30 db up to 45 db and Richard does mention 45db
I found this High Fidelity test that measured separation at 29db...if 45db is because of RM's upgrade that is really nice.
