Preamp Deal of the Century

Well, it's been 3 weeks with my Cortese and I am torn between the most wonderful music in my listening room that I can remember (over 30+ yrs) and noisy tube problems. I've got one of Mick's latest Cortese preamps. It was delivered with the adjustable output gain on the back for matching various amp inputs, XLR/RCA's (I use RCA's only), remote control volume (which works perfectly and is a blessing for this old body!), and what Mick states is his latest choice in a tube configuration for the line stage amplification section (1-6SN7 and 1-12B4A per channel). I've now gone through 3 sets of the 12B4A's and finally got a set that won't sit there and "spit" at me. Now one the 6SN7's is doing a "whistling" act. I came from all solid state (Spectral) system and I'm accustomed to quiet. But then again, I've never had music reproduction like this pre gives to me, not to mention that it has reintroduced me to VINYL which in itself is most rewarding. I've ordered a complete new tube set-up in hopes for a reprive from the noise. HELP

Asa, coming from the pro audio arena where SS rules (except for the mic pre's and compressors where we are looking to tame digital) I've been extremely happy with my ALL Spectral/Avalon system for many years.
Had my friend not pick up on a used Cortese and introduced it to me, I'd still be there. But as yo know for yourself, once you experience what Mick's creation can do for music enjoyment, you're hooked (at least to Mick's gear). I was curious as whether there is an amp out there that would make a similar improvement to my enjoyment. I know Mick is talking about some 100W babies and if they were available now, I'd order them sight unheard. I'm that confident with what he is doing, but they aren't and according to Mick it may be a very very long time before he can resume that project as he is so busy building pre's for all of us. I thank you for you candid comments and most likely will retain the DMA360's. They are incredible amps!

Jeff,I recenlty bit the bullet and joined the many others with the addition of the Cortese to my previously all SS system (Spectral). It is the most rewarding thing I've done is the last 10 years! Not only am I now enjoying music reproduction like never before, but I have rediscovered vinyl which has totally made me rethink how digital will play in my system. How ever long the wait may be for your Syrah, wait. You will not be disappointed.
Now i have question for all the Supratek pre owners participating in this thread. I have Avalon spks (88db), presently drivinng them with Spectral DMA360 mono blocks and am very pleased with their performance (now that that the Cortese is driving them). But since I was so blown away by the improvement that the Cortese made when it was introduced into the system, I am wondering if you have any reccommendations for an amp(s) for my system. Power is a requirement (certainly a minimum of 100w per ch)
