A couple other thoughts, which I should have included in my earlier posts
on the subject:
the Steelhead is dramatically affected by the tubes used; if the loaner is the
one that you thought sounded noisy, that raises additional issues about the
tubes; there are a number of threads here about what various tubes sound
like in the Steelhead, but if you were to go out and buy top drawer NOS
tubes for your listening tests, that's going to add to the expense (although
giving it back to your friend with some killer tubes might be a nice gesture
if he is willing to give the unit up for a week to let you play with it- and have
it on hand as needed to compare with others).
The Allnic requires a fair amount of burn-in time- figure at least 100 hours
minimum, and benefits from a better rectifier tube than the one it ships with;
The ARC-- I'm not up on my latest ARC gear ( though I've owned many
pieces of their equipment, starting in around 1974-5) but that may also
require some serious burn-in; I'm not sure about the phono stages, but I
see very high burn in times for the line stages;
You want to pay attention to this, even though the dealer ought to. In some
cases, the dealer should have a 'house loaner' to make available.
I've also heard good things about Paragon in Michigan, which handles the
Doshi equipment.
You can buy an RIAA 'converter/adapter' (for lack of a better word) that
enables you to run a CD into the phono input to accelerate burn-in time
when you are not listening. KAB sells one pretty cheaply, and it works.
