"I recently purchased a Pro-Ject Debut Carbon DC turntable from you, and I am really impressed with the level of detail and customer service I’ve received so far. The instruction folder is a great touch, and your excellent site gave me tons of info and insight into buying and setting up the turntable. Bravo!" - P. Cuffari
"Wow. I just got the turntable. It is amazing. I love the bags, I love the fact that I got it literally less than 24 hours after ordering, I love the cartoon easy set up pics, the stickers, record cleaner brush, and the sound is great for the money. SOOO Happy!! Thanks guys and gals--you just created a customer for life."- R. Montgomery

Proud to be a Labhead." - G. Laurie
