I would like to also stress the service SF provides. I bought a Phono1 on Audiogon that was the 54db gain. This was not enough for my Helikon, so I called SF, talked to Nick, and he said to ship it to them and they would swap out the required resistors. The only thing I paid for is shipment back to SF. Great service, great company.
Sonic Frontiers Tech Support is Great
The friendly gentleman Nick Spent 15 minutes on the phone with me discussing a minor adjustment on my SFCD-1 CD Player, & Tube selection etc. today. He is great very knowledgable , Patient & helpful. He was also kind enough to send me some screws for the case at no charge. A very nice company to deal with!
