"Yeah and the Rhea also has 10 tubes. Re-tubing it will put you out of $700-$1000 easily." Really? $70 to $100 per tube? I am sure you can replace tubes for less than that. The Rhea and its cousins from Aesthetix are very good sounding but do tend to exhibit electronic noise when pushed too hard. It seemed to be the nature of the beast when I owned one, and expensive tubes do not cure that problem since it is inherent to the circuit.
As to the issue of signal and noise. There are two sources of noise, the electronics and the medium, in this case vinyl. You want the signal to noise ratio of a phono system’s electronics to be at or below ideally the optimal low noise inherent to vinyl, which is around 60 to 70db below signal, at best. Guys who build their own stuff are always talking about having too much gain and wanting to build their equipment such that the gain is as close as possible to what the system needs to produce the SPLs that satisfy them, so they can get away with very little attenuation. I understand the idea but my experience is to the contrary; I would rather spend money on the best possible attenuator and have an excess of gain in my phono stage. To me that sounds quietest when achieved.
