"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
"I love the Turntable Lab, great service & great products. There's no other store or site I'd rather buy my gear from. I'll sure keep on purchasing my equipment from TTL."- D. Martinez
"It's always nice to feel like you're appreciated, and you guys have done a great job with that."- R. Abeel
"Turntable lab constantly deliver the best and most current selection of modern music on all formats. It's my first stop for vinyl house and disco music. The reviews are accurate and I can trust the buyers to source quality product. Customer service is second to none and Bret has been nothing short of outstanding in every interaction we've ever had. Proud to be a Labhead." - G. Laurie

I remember when I first discovered Turntable Lab by searching online for DJ equipment. I was looking all over for different equipment that I needed and when I found TTL I was relieved to find out that you guys basically had everything I was looking for." - C. Arroyo

"The Tube Boxes have been an integral part of our product portfolio for many years. Now, the new Tube Box DS3 B adds balanced in- and outputs to the beloved tube amplification. This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components. You can connect two turntables at the same time & easily set everything on the front plate. Each input settings are stored in the memory. Large ranges from 40dB up to 65dB are possible. You can perfectly match it with a wide variety of cartridges and integrate it into the rest of your Hifi system, matching the volume levels accurately to other sources like CD players or streaming devices. Load impedance can be set continuously via potentiometer, a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust the impedance during playback and immediately assess the impact of different loading options. This is necessary to find just the right load impedance for your cartridge. No other manufacturers implement this feature in this extreme way." - Pro-Ject
