The Denon PRA-2000RG (RG stands for Reference Gold!) is a Japanese market preamplifier with a true factory 120V U.S voltage conversion. It sold for 330,000 Yen back in 1990 Japan, which in today's dollars works out to $6k.

This piece was originally sold and serviced by Analogique in NYC.

It's one of the flagship Denon preamps with a very capable and sophisticated MC/MM phono stage built-in, which is selectable from the front panel control section.

A quick look inside and around the back panel shows us that this is in fact something very special. This is the first time we've ever seen one of these in our shop and we were very impressed. 

Just look at the high quality parts selection and plethora of high quality connections on the back.  

It is finished in rose gold in conjunction with a high-gloss wood case.  

The volume knob also has a band of wood around it which is a classy and unique touch.  

This video (not from us) shows off some of the intricate insides...

Our Testing Process for Preamplifiers at SkyFi:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.

At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.

Final testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage Kef speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
