I bought this deck in 1988 for $700 Canadian. It was produced for 87-88. It was a good deck in its day, but hardly a high end product. I would say this deck is mid fi. It was rated 20-20khz with metal tape, using a Hexelam 3 head system. It used a Ferrite erase head. It was single capstan only. It also used 2 motors if memory serves. This deck was rather basic for a 3 head deck. Decks from Aiwa were better engineered then this Luxman. Even Luxmans K-03, K-05 decks were way better. You pick up a K-112 and its quite light for its size. Looking inside at the circuit board makes you wonder where all the money went. The Star Circuitry is nice though. The cassette door is rather flimsy. When the logic controls are activated the head system moves up or down with a loud thunk sound. My main beef with this deck was its 5 LED meter display. Most decks have more range on the meters for recording. This deck does have fine bias with HX-Pro, but you have to ear it when setting fine bias. There is no provision to have tones set to help set bias. The K-05 deck was probably Luxman's best deck as it was rated 15-27000hz on metal tapes, and had computer aided fine bias. It also used dual capstans which the K-112 lacks. When I had this deck I mostly used Dolby C, so that's where the sound was remembered using. The soundstage was somewhat compressed using Dolby C. This deck did have a warm sound though. If I had this deck today I would compare it against my Sony 909 deck and the Aiwa 9000. Still I have fond memories of this deck and I would buy another one since they go for next to nothing on Ebay these days. Keep in mind the Hexalam head does wear and is no where as strong as an amorphous head newer decks use. From a few years use my heads were already starting to feel a grove pattern in them.
For others keep note the info on the description section was written by me in error of the proper section. It should have been moved here. Regardless my comments in the description section are what I think of this deck. As mentioned I sold the Luxman in 93 after owning it for 5 years. I did have a service issue with mine. I find the Sony and Aiwa decks I have are better decks, but also more expensive. For memories sake I just purchased another K-112 to give it a second listen and compare it to the higher end decks I have. All I remember about the sound of the Luxman was it seemed compressed, but this may be more due to Dolby C then anything. I'll post another review of this deck when I receive the second K-112. This deck was produced in 1987-88. A newer similar deck is a K-373. Luxman since the K-03 and K-05 decks, never really went high end again. I would suggest looking for a K-05 if you can find one. That deck was rated 15-27khz and had Dolby C. It does lack HX-Pro though. No Luxman deck ever used Dolby S, even when Dolby S was available to use, and as such didn't produce decks of the standard needed to use Dolby S (since the K-05). I will be very interested to hear how this old Lux fares against newer decks. I will try it with Dolby Off as well as Dolby C and try my other decks with it. A price of $600 US or $700 Canadian is not a lot of money these days for a better deck. I consider decks of $1000 and over in the higher up range. For reference the Aiwa XK-S9000 deck (Aiwa's best tape deck ever) was listed at $1200 US or $1600 Canadian. Some people still may prefer Nakamichi's as well, but those decks there is a compromise with the tapes it makes. I have openned the inside of the K-112 and its rather empty inside there. Plus parts from other manufacturers. And this deck is only a single capstan 2 motor design. Biasing is manual, so you better have good ears to get it right.
