Compared with a typical used keypad/zone controller, US$100 is a touch above the US$87 median but still well inside the normal spread for this niche piece of whole-house audio gear. It is not a bargain-bin score at US$29, yet it is also comfortably below the US$170 upper quartile, so this reads as a fair buy rather than an ambitious ask.
What makes it worthwhile is the integration: these Russound keypads are purpose-built to give MCA systems a clean in-wall control point, which is exactly what buyers of distributed audio are usually after. If it is working properly, includes the wall plate or mounting hardware, and matches the controller you need to pair it with, it can be a very practical pickup; the main thing to confirm is compatibility, since these are system-specific rather than universal.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Display Technologies does not appear to be a recognized brand in the hi-fi or consumer audio industry. Extensive searches yield no verifiable information on its origin, heritage, product focus, or market position among audio enthusiasts. Instead, results consistently reference general advancements in visual display technology, such as cathode ray tubes, LCDs, LEDs, and OLEDs, spanning from the late 19th century to modern innovations.
No records indicate a company by this name producing amplifiers, speakers, turntables, DACs, headphones, cables, or any audio equipment. It may be an obscure entity, a misnomer, or unrelated to hi-fi, with no notable founding year, country, or founder tied to sound reproduction.
Hi-fi buyers should verify the brand name or consider established alternatives, as fabricating details for an unconfirmed marque would mislead. If this refers to a specific niche player, further details from the querier could clarify.
