I opted against Pure Class A due to inefficiency and room heating heat rejection. Mono blocks were chosen in keeping with the compact footprint common to the ‘9’ series of products, including the PH 9.0\/X\/T, Analog Bridge and LS 99 preamp. I felt efficient use of space to be a critical factor in todays world. Chassis and aesthetics are clean and elegant but simple, reducing cost, allowing us to focus on component quality and design for best sonics. Lastly, amber illuminated power VU meters were chosen for a vintage tone aesthetic that I believe embodies the design concept.\n\u003cbr\u003e\u003cbr\u003e\n\u003cb\u003ePOWER RATINGS\u003c\/b\u003e\n100W at 8 ohms.\u003cbr\u003e\n200W at 4 ohms.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr style=\"border:none;height:2px;width:100%;margin:50px 0;background:linear-gradient(to right, transparent, #000000, transparent);\"\u003e\n\u003c\/div\u003e\n\n\n\u003cdiv style=\"max-width:1200px;margin:0 auto;font-family:Arial,sans-serif;color:#333;\"\u003e\n\n  \u003c!-- Title --\u003e\n  \u003ch2 style=\"font-size:56px;margin:40px 0 30px 0;font-weight:800;\"\u003eTechnical Spec\u003c\/h2\u003e\n\n  \u003c!-- Grid --\u003e\n  \u003cdiv style=\"display:flex;flex-wrap:wrap;gap:40px;\"\u003e\n\n    \u003c!-- Column 1 --\u003e\n    \u003cdiv style=\"flex:1;min-width:280px;line-height:1.6;\"\u003e\n      \u003cstrong\u003eFEATURES: \u003c\/strong\u003e\u003cbr\u003e\n(1) RCA input.\u003cbr\u003e\n(1) XLR input.\u003cbr\u003e\nRCA and XLR inputs are transformer coupled to input stage with floated ground.\u003cbr\u003e\n(1) Pair 5-way Binding Posts – Positive (+) Red, and Negative (-) Black.
