Tweaks: Gold-plated DIN to GP Ultra-Link RCA with OFC cables (custom rigged by me and a pain-in-the-ass to solder).

System Goals/Comments:
System Strengths: Quad 405-2 Zezoff/Folsom modification and stacked KLH and a/d/s/ created the following:
- Superb, focused, detailed soundstage attained with a mid hi-fi system.
- Low noise (Quad/ADC combo), fast transients with large digital and/or analogue soundwaves.
- Realistic subwoofer levels.
FYI: Quad package was purchased for less than a quarter of the original retail price. All of the above!
- Henry Kloss Tivoli Audio Model Two AM/FM Stereo Tuner, highly recommended with high selectivity and capture ratio.
System Weaknesses: - KLH Six high frequency rollover at 14 kHz and besides I can't hear beyond 14 kHz.
- DIN plugs are a pain-in-the-butt to solder but the connections are solid and secure. With a stacked Boston Acoustic A40s resolved the high-frequency issue (extending to 20,000 Hz).
Video/HT System: None
TV/Projector: Sony Bravia KDL26S3000 LCD HDTV
