Hmm, I called ARC with a few tube questions not too long ago and had fairly long chat with them.
Why was the entry level line at Audio Research eliminated?
One of my first tube preamps was the SP-16. I believe it was the last preamp that founder William Z. Johnson developed. Price was around 2K-2.5K w/phono. It was an excellent reliable preamp. But now if you want a new entry level ARC it's not available. Too bad. Was it just not profitable. It was an excellent way to get into their gear and move up the ladder over time.
