For this amp review the following equipment was used: Analog sources were a VPI TNT Jr. turntable, with cost-effective upgrade and outboard flywheel, on a Bright Star base and a Townshend Seismic Sink. Tonearms were the Graham 1.5T/C, and Clearaudio/Souther TQ-1. In my small room, a VPI HW-19 Mk.IV with a SAMA and mounted with a Clearaudio/Souther TQ-1 sits on a Bright Star J-7 base. Cartridges included the van den Hul MC-1 Super, Dynavector XX-11, AudioQuest MC-200, Fidelity Research/van den Hul FR-1, Denon 103/van den Hul, and Denon DL-S1.

TL-2 CD transports and a Sony TCD-D7 "DATman" connected via coaxial, AES/EBU, Toslink, and AT&T optical connectors to EAD DSP-7000 III or EAD DSP-9000 III D/A processors.

Preamps in-house were the Threshold T-2 and Carver Research Lightstar line-level units, with Vendetta SCP-2C, Audio Research PH-2, and Gold Aero dB-45 outboard phono units.
