Gents, I promised some background on why the LF is designed the way it is. Here we go.
Background
I am about to make comments on the case designs of amplifiers. You guys should know that I am probably a bit older than you think. I grew up with tubes. I built lots of tube equipment, from push-pull 6V6 and 6L6 amps to test equipment to high voltage equipment (where I almost killed myself, no joke). I have seen a lot of tube stuff and I have seen many tube amplifiers, including the original Dynacos when they were, well, new.
Now before I go further, please realize that I am giving my personal opinions about looks. When I was at RMAF last October (first show where CA was a vendor) I had a chance to meet Ray, Todd, Justin, Jason, Jack, Craig and to say hello to Alex (Audeze) again. Everyone of these individuals was extremely gracious to me and CA.Everyone expressed encouragement for the new venture. I think we're pretty lucky to have these guys, as well as many others, making equipment for us.I appreciate each of their design styles and visions and some of the very cool things that they are doing.
But, I have seen sooooo many amps with tubes sticking out of the top plate. So many of them. Some of them really beautiful. I wanted to do something else that brought together some different ideas. Most of you have told me that you really like the LF design. Some of you don't like it much at all. Whether you do or don't, here's why it looks the way it does.
Ideas behind the design
There are three things from my own experiences that I wanted to bring to the LF:
1. Tube consumer equipment always had some kind of ventilation back panel. Often this was pressed board with round holes or slots. I liked looking through the ventilation holes to the tubes inside. There was a very popular and widespread radio design called the All American 5. It had 5 tubes whose heaters, when in series, added up to about 110V. The circuit design is classic. You can find descriptions of it on the web. The amp was as dangerous as you can imagine. The plate voltage was taken directly from the line (no transformer), half-wave rectified. It was common for the actual metal chassis in these amps to be electrically hot. Hence, they were always enclosed completely in plastic, including plastic volume and tuning knobs. These were the radios that killed you if you dropped them into the bathtub while you were in it. Anyway, I liked looking into the tube equipment and this is why the LF has windows to look through instead of tubes on the top.
2. Sports cars and motorcycles. Many years ago I had two BMW motorcycles. One was a 750cc cafe racer with a quarter faring. The other a 1000cc full faring touring bike. I rebuilt the second one from a wreck. Increased the HP and had it custom painted. I drove way too fast in the canyons of Arizona and around the western parts of the US. If any of you wants to know, remind me to give you my four rules of motorcycling. I like the colors and custom work on motorcycles and I like the looks of very expensive sports cars (like Ferraris and Porsches). The color in the LF is designed to give the sense of the color and speed in sports cars and motorcycles. The red and black are common in high priced, fast cars.
The finish on the LF is designed to be the inverse of a red car with black tires. The powder coating (the tire color) is actually very difficult to do. A super flat black shows every imperfection in the paintwork. Although it may seem an inexpensive way to do a finish, it is more difficult to get it right and, hence, there are rejects that have to be discarded. It is much harder to do this than to anodize (although I have gone to anodizing on the LL because the LF finish has been difficult to control).
The red paint on the knob and power switch is put on by two very talented guys who do custom choppers here in Austin. These guys are artists at what they do. At one time they worked at Texas Custom Choppers until the owners were made an offer for the property by a Mercedes dealer that was impossible to refuse. When you look at the knob and power switch, they were totally custom painted to bring some high-speed motorcycling to your listening experience.
BTW, the power switch has its own process. First I make the aluminum housings. Then I have them custom painted in the needed color. Then they are shipped to the piezo switch manufacturer who builds in the piezo switch and fills it with epoxy.
3. Weight - some of you have made comments on this. I wanted to create the opposite of a heavy tube amp. That is, I wanted something had high performance and light weigh like ... a performance car. It is easy to add weight to anything, but often very difficult to take it out. Folks who engineer jet fighters, racing cars, etc. are always looking to remove weight not add it. I realize that this is, perhaps, a different thought from much of the audio industry, but it was a design goal. Hence, the compact size, rcore transformer and some of the other design elements.
Naturally, some of you will agree and some not. That's ok. But, now you know.
More to come...
