Solid-State PREAMP - Thoughts on Threshold / Krell / Bryston

Narrowed my search a bit more.
Thinking more along the lines of a QUALITY, simple, gently used Solid-State Unit.
(MIGHT be able to get my hands on a nice Threshold FET-9 at a reasonable price.)

I KNOW that most "Audiophiles" rave about Tube gear, but I’m not quite ready to jump onto that bandwagon just yet.

For those who have owned and/or auditioned such gear -
It seems like Threshold FET-10/H & 10/P (particularly the later "e" series) should be pretty comparable to the
Krell KSL / KPL product line
The reviews I have read seem to indicate that the products from both should be awfully close to "uncolored"
(perhaps to the point of mild sterility / boredom)
But either should be a QUANTUM-LEAP up from my NAD Receiver that is presently serving "Pre-Amp Duty".

I also perused some articles on DIY Audio and it would seem that re-capping the FET-9 and perhaps updating or replacing the Power Supply Module could potentially be something within my technical abilities and could reap further improvement - possibly approaching that of the later FET-10/e series
