The Classic KLH Model Six designed with the Midas touch of the late, great audio pioneer, Henry Kloss, stacked with a pair of a/d/s/ L300.
- Boston Acoustic A40 foam surrounds dry rotted. A great sounding speaker especially stacked with the KLHs .

|Speaker Cables/Interconnects:||Stacked KLH and Boston Acoustic|
- Super OFC Series Phoenix Gold 16 ga. with Radio Shack GP banana plugs connected to KLH Six
- NeoTech HD OFC guage unknown connected to Boston Acoustic A40
|Other (Power Conditioner, Racks etc.):||Data Guard Industrial power bar (el cheapo)|
|Tweaks:||Gold-plated DIN to GP Ultra-Link RCA with OFC cables (custom rigged by me and a pain-in-the-ass to solder). |
- Upgraded KLH Six crossovers with Solen caps, OFC and 24k GP Puresonic 6179 GP binding posts.
- Upgraded Quad 405-2 with 24k Puresonic 6147 binding posts and WBT-0201 Coaxial sockets RCA.
|Room Size (LxWxH):||20.5 x 11 x 8|
|Room Comments/Treatments:||Wall-to-wall carpet, one-half length of wall covered with vinyl records and contemporary art. 225.5 square feet|
|Music Preferences and Comments:|
|Music Used (Genre/Selections):||Diverse, Obscure, Progressive and Eclectic: Classical (Bach to Stockhausen), late 20th century contemporary music, Funk, R&B, Soul, Gospel, some Jazz (Davis, Don Ellis, Hancock, Purim) plus Zappa, Rundgren, Beefheart, Kraftwerk, Beach Boys, etc.|
|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).
