Well said, Lou.

Re the two phono preamps,  there is very large price difference but the 
bigger significance here may be their apparently different purposes. The RDL 
seems designed to work with a common moving magnet cartridge. Whereas the 
Time Step appears designed  for the more exotic and lower output moving coil 
cartridges. In the test recordings I wonder if this has been taken into

A good friend who is into restoring analog tape recorders such as Ampex has 
a clever and true watch phrase:
“before everything else, make sure the tape runs and is aligned perfectly.” 
all else follows; without that nothing matters. I am paraphrasing…

Analogy for this is perfect playback from the groove - the recording chain 
after that is trivial these days.

That said, I will listen!
