Bruce, thanks! I built the pre, amp, and speaker stands myself out of figured maple and walnut for the corners. I got the wood on ebay from antlersexpress. I also got some big slabs of walnut from him for an equipment stand.
Anyway, I'd go with an EL34 SET, I don't like digital amps but I know a lot of people think they have improved to the point where they are a decent option... I have never heard one that was anywhere close to my SET amp. I have only heard a Trends t-amp and a Virtue on Omega speakers before though.
I agree with what you are saying about the Neotech wire. Initially I thought some high freq info must be missing, but then I realize it is only distortions or sounds that should not be there in the first place are missing, and what I'm hearing is more detailed, accurate and easier to listen to vs. literally any other wire I've ever used. I'm not sure about going through the port, maybe ask Louis about that one.... but I would say that getting rid of the brass and steel connectors will make for a nice improvement in sound quality.
Also, I did make some ICs out of the neotech wire using 24 ga. I also used 2 runs of 24 ga gold plated occ copper w/enamel insulation for the ground, it is sold on ebay through clairvoyant cables and is pretty cheap for occ copper wire if you win an auction for a good price. I used Furutech RCA plugs with an occ copper center pin. They are also the best ICs I've ever made or heard....
