Frazeur1,
I decided to first try tubes I could walk into Guitar Center down the road and buy for $20 each first. The Groove Tube Gold 12AX7s I bought solved the problem. Also, surprisingly, I am hard pressed to hear a difference from teh previous ARC stock tubes that came in the SP16. Perhaps a tad more background noise in the phono section, but nothing of any consequence.
So far, I do not feel a need to order tubes from ARC. I could still decide to do that and keep these as an extra set, but I cannot justify it currently.
I picked up the 1m MIT terminator ICs on Ebay several years back for <$50 each, as I recall.
I also bought a pair of .5 m Harmonic Tech ICs from the Essential Audio Tweaks store on ebay for much more along with the DNM Resons, which were comparable to the MITs in price more or less. All of these are good but different with different strengths and weaknesses.
