Hi:
I currently own the Spiral Groove SG1 Turntable. This turntable provides world class sound, and it has transformed the analog sound in my system.
There are two tables made by Spiral Groove:
1. The Spiral Groove SG1/Reference Retail $25,000 (My turntable).
2. Spiral Groove SG2/ Retail $15,000(I have heard it once at a show,and it is quite good).
I am using a Graham Phantom in my setup. Although, I understand that Allen Perkins is in the process of designing his own tonearm (Which I have not heard yet, but, I am sure it is going to be quite good).
I bought my Spiral Groove SG1 from Precision Audio in Moorpark,California (Southern California).
