Ritteri, the Parasound 2000 suffered from too many cooks spoiling the soup as nobody was in charge of voicing the unit, essentially a state of the art electrical design, close to the line amp in the Dennesen JC-80. It can be cleaned up and made to sing, but in stock form the Adcom will blow it away......We are in the talking stages of designing a new Parasound preamp which will be designed by CTC...
Hi Ritteri........Just a bit affiliated as Curl, Thompson and Crump, CTC Builders, designed the JC-1 monos for Parasound after we spent a couple years on the CTC BBQ, a highly modified HCA-3500.....I chose the parts, voiced the amp and was project manager of the JC-1 project, Curl did the changes to the circuit and Thompson designed the boards......We, CTC, also build a very expensive preamp known as the CTC Blowtorch and I own TG Audio that builds accessory wires......Lots of work to clean up the HCA-3500 as deleted about 200 parts, replaced them with about 80 and had to have new metalwork made for the top and front......The amp served me well for about three years and recently was replaced by the JC-1s which are just in a different league from the modified HCA-3500 due to Thompson's layouts.......Smoother, much faster and cleaner are the differences I hear here with the JC-1s over the CTC BBQ.......If you are still interested in modding the HCA-3500s then contact me, but think you will be better off saving for the JC-1s.......
