I have two questions...a little history first. I bought my Heresy 1 in 1985 it was a floor model so I paid $1200. I also bought a carver 500 amp and a couple of technics 1200 mk2's. I used a straight 4 channel mixer (realistic). This had a great sound. I'm wondering if I should get a carver 1400 preamp, would it sound better? Or should I keep what I have (sound is good to me). Also I am wondering what wood is under the black paint. I don't have the serial numbers from the back. Is there any other way to find the. Ok that's three questions.😎
