Professional Grade Workhorse
I own two other items from Radial Engineering: the JDI Duplex passive DI and the Reamp JCR passive re-amping device. Both are solid, sonically transparent, pro-grade pieces of equipment. So, no surprise that the J33 turntable preamp lives up to the standard I've come to expect from this company.
The J33 provides a nice upgrade from the stock preamp on my early '90s Kenwood consumer-grade receiver. I'm feeding signal into the unit from a Technics SL-1210 MK2 turntable equipped with a Shure M97XE cartridge. The J33 (powered by the included 15v 400 mA power supply) passes mic level signal into an RME Fireface 400 and then into the box at 48kHz/24 bit. The resultant audio is well balanced and pleasingly musical without noticeable coloration. Further in-the-box edit/resample/dither to redbook yields audio that compares favorably with commercially produced compact discs. Even the mp3's turn out nicely.
This piece features bulletproof construction and well thought out design. For me, it is a significant upgrade and solves the missing link in the vinyl-to-digital chain. Truly deserving of five stars.
As always, excellent customer service from Sales Engineer Mike Harris (x1382) who has been my go-to resource for close to a decade.
