Well -- odd experience, I left for work (just a half day today), and left the Io turned on. Got back 4 or 5 hours later, put on a record, and no sound. No hum, no music audible even with the volume cranked. Same through my headphone amp. All the tubes in the Io and power supply were glowing fine.
So I switched back to the Rogue phono stage and got music. Next step: fuses. Checked the two on the back of the Aesthetix power supply, and the B+ fuse is melted about halfway down with a burn mark. It's one of those slo-blo fuses that look like a spring wrapped around a wire, and the spring has separated (though the wire inside hasn't).
I'm going to get a new fuse tomorrow, but I wonder what made it blow (if blown it is). Power surge? Maybe when I turned off the amp or took off the needle before I left?
Also, it seems odd that all the tubes in both units would have stayed glowing given that the B+ fuse was blown...
Frank, I am certain that the Dyna is the source of the tubby bass - looking forward to hearing what it sounds like when I try a different amp. Maybe I'll switch my Aleph 3 back in for fun (though its bass is not stellar either). I have my eye on some C-J Premier 12s.
