The weakness? It is ruthlessly revealing. A bad recording (or a scratched CD) sounds worse on the DR1 than on a portable player. This machine has no mercy. Sony discontinued the SCD-DR1 in 2009. Only an estimated 500 to 1,000 units were ever made. Today, on the rare occasions one appears on Yahoo Japan Auctions or a specialty dealer’s site, it fetches between $8,000 and $15,000 —often more than its original retail price.
That machine is the .
This heft comes from Sony’s "Frame and Beam Chassis" —a 5mm thick aluminum base plate combined with a 1.6mm steel inner chassis. The transformer is not bolted to the chassis; it is isolated on its own sub-chassis, suspended in a resin-damped housing to prevent magnetic flux from bleeding into the audio circuitry. Sony engineers famously measured the vibration of the transport mechanism using laser interferometers, then redesigned the foot spikes three times to direct resonance away from the D/A converters. sony scd-dr1
You can put the SCD-DR1 on a flimsy IKEA table, put your ear to the chassis, and hear nothing . No resonance. No whir. Just the absolute void before the music. Here is where the DR1 becomes a philosophical object. Most SACD players in 2006 used generic delta-sigma DAC chips from Burr-Brown or Analog Devices. Sony, however, went in-house with the CXD-9957AR —a custom 24-bit DAC designed specifically for the DR1. The weakness
