Well, I have been comparing the Cortese(stock tubes) to the the Syrah (stock tubes). Thus far I am only listening the line stage with my Resolution Audio Opus 21 player. The Cortese is better by what I consider a small margin. More refined and and in control is what I would say. Then my NOS tubes showed up. I ordered these based on the info Bwhite gave me on what NOS tubes to use in the Syrah. Thank you so much Bwhite and others. Your ears are very good. Now going head to head, the Syrah with a Mullard 5AR4/GZ34 and the Ken Rad black glass VT-231's vs. stock tube Cortese!
The winner - very close and it just comes down to personal taste. The bottom line is for the money the Syrah with these three tubes is a better value to me. It is half the price and with NOS's almost all of the sound, if not all, in the line stage anyway. I understand the phono is better on the Cortese also. I am still looking for KT-66's Genalex or 350B's. I am sure this will put the Syrah in the giant killer league. These last tubes just cost to much and I am not sure I will ever pay that much!
I also have a CJ 16LSII in my home for the weekend. I never though CJ was all that good, but I am dead wrong on this one. Forget what you hear about it being slow, thick, lush or whatever. To be frank I feel it bested both the Cortese and Syrah in my system - line stage only, but I cannot afford it even used. It is very transparent and beautiful sounding. It is in the same leauge as the two Supratek units in the highs and mids, however it has a little more bass weight and foundation. I do like this as it makes music sound more live to me! But remember the CJ costs $8500 new! The Syrah with the NOS's costs less than 1/3 and has phono! I also find the Syrah with the NOS tubes mentioned sounded 90% as good as the CJ in my system. Perhaps the KT66's or 350B's would then cause the Syrah to be on par or better than the CJ. This is amazing for the money folks. I mean amazing.
Outside of the costly 350B and KT66, please give me a NOS tube that is affordable to use in the power supply. My Syrah has three tubes like the Cortese in the power supply.
I did open it up and while both have 3 tubes they are very different on the inside. The Cortese has many more parts and is laid out more cleanly.
