Hello Paul,
I will never own a Cortese. Not because of monetary issues but I just do not need one.
I use a Chenin FF preamp with Mullard 8080 and Amperex BB's on the phono section. I have an Altec 604-8G's in OB and 612C Altec cabs, a Fostex MLTL, and a Bozak Rhapsody. They are 100dB, 95 dB, and 92 dB respectively. I am very happy about the synergy and the preamp does not hum even at maximum gain settings (per channel) of the phono and minimum attenuation (full) of the linestage volume.
Before the Chenin, I was using a Wright Sound WPP100C. The Chenin phono is much much better than the Wright! No comparison! Besides, you need very quiet tubes on the WPP100C or you will hear "tube rush" or hiss as you increase the individual gain pots on it. Not a problem with the Chenin. Very quiet!
After that, I went a little "pie tasting" if you will. I had the Pass Xono, Hagerman Trumpet, and a heavily modified Hagerman Cornet II. I do not care for the Pass, The Trumpet was very nice, and i can get very close to the sound of the Trumpet with the Cornet II. So I sold the first two and kept the Cornet.
Like you, I played vinyl almost exclusively. Hell, check my equiptment page and you will see that I am telling the truth. Besides, now that I am on the SET/High Eff camp, hum issue is a no no to take advantage of the speakers high efficiency in order not to mask the small nuances that contributes to the listening experience.
My experiences in the context of my own system only of course!
regards,
Abe
