One of the first places we visited Friday morning was Kevin Haskin’s DIYCable room, chock full of goodies for the well, you know, the DIY crowd (more on that later).The first thing that caught my eye also took me so off-guard that I failed to snap a picture in time to document the event. It was a record (no real surprise there), and it was spinning (duh!), BUT it was so seriously warped (think scalloped) that I immediately began asking around for some Dramamine.
Were my eyes closed, however, my ears would not have noticed anything amiss. What kind of table/arm/cart combo does it take to track this kinda’ torture? Here are my notes, transcribed from a chat with the designer.
So, whatcha’ got here?
“I’m introducing a new turntable using my Well Tempered principles, and the name of this model is the Well Tempered Amadeus. And it’s going to be a package with the table, the arm, a Grado cartridge and a phono stage for under a thousand. I’m going to make it as far under a thousand as I can get. It has revolutionary levels of performance. You know, I’ve stared at that flutter meter literally hundreds of hours improving the bearing, improving the damping, improving the motor drive, improving the belt … I’m tired!”
I gotta’ ask about the, you know, about the …
“The golf ball is a result of me sitting there drinking coffee one morning when an idea leaped into my head about the bearing. I play golf and I thought … you know, ah… a golf ball and a bearing and some silicon damping fluid … within three hours I had one made. I listened and said, ya’ know what? This is it. I’ve made several iterations of it, but the golf ball … well, perhaps you know … golf balls are very precisely made, and comparatively speaking, they’re cheap! You can buy them at the swap meet for 25 cents. If you were to try to machine a perfect sphere like that, you know, we’re not talking 25 cents. Furthermore, this one has … I have a smiley on this ball … somebody marked this with a smiley and I included that … there’s no extra charge.”
After some chatter about the possibilities of tweaking with cryoed Titleists and other brands of balls, we manage to move on. What’s with the platter?
“It’s MDF … I experimented with lots of different materials for the platter. This is the highest grade of MDF and it works so good I’m afraid to do anything to it … you know, paint it, finish it … put a surface on the top or the bottom. No, I think we better just leave that right alone. I don’t have a fingerlift for the arm, although you can have one if you wish, because the fingerlift is just something else to cause trouble. So I just lift it up like this.
Yea, that’s how I do mine (the Space Arm on my Space Deck is ah ... rather ... uhm ... Spartan, too).
“Uh-huh. And, don’t tell anybody, but you know what kind of mat that is right there? It makes an excellent shelf-liner … that stuff that goes in the bottom of your kitchen drawers, It makes a fabulous mat.”
Price?
“Turntable, arm, cartridge … phono stage to which you are now listening … under a thousand. I’m going to make it as far under a thousand as I can. I don’t have a good handle about manufacturing costs yet, but … we’re gonna’ make it happen.
Thanks, Bill.
“Bill Firebaugh, Bill the Fireball of Well Tempered Labs.”
Bill is indeed a fireball, and even more refreshing, I got no sense of him giving me a typical sales pitch. To hear him talk, you’d think he was a kid who just built his first table. His enthusiasm and sincerity makes him one of those people you just want to be around.
Note: Bill Firebaugh started designing the Well Tempered Arm during the mid 1980's in his spare time. Bill was a key member of the Ford Aerospace think tank, so finding unique solutions to complicated problems was nothing new to him.

Is that the CSS WR125S in the picture?
How were they?
Did you hear the version without the tweeter and running full range?
Thanks for any comments.

Yes... that is the new 4" XBL^2 driver that CSS is producing. We had both a MT two-way which could be wired without the tweeter and a line array using several of the WR125's, ribbons and a couple powered 8" drivers. The MT worked very well in the smaller room with the extra room gain. In fact... they were very usable without a sub in the smaller room.The response on the 4" is very flat out to about 14Khz. We had it wired both with & without the tweeter and I prefered it with the tweeter. A simple tweeter crossed high with a single cap and leaving the 4" to roll off acoustically should work wonderfully. Once I get a couple drivers I'll mount them on the baffle and do some measurement and simulations. The tweeter will probably need to be padded also, depending on the tweeter, but overall it makes a great small two-way. It really is a great demonstration of XBL^2 that the 4" driver is usable at all down to 50HZ. I have plans to use it on a couple projects including a small computer monitor speaker.
Thanks.
I'm trying to decide if I want to take advantage of Bob's early order special.

Thanks for the post Stephæn.... Bill is one of those guys that I really enjoy working with. He is 100% engineering and 0% hyperbole. He approaches design with an eye towards identifying a problem, quantifying it and then seeking out a solution, which also can be quantified to verify improvement. His love of music drives his creative efforts and as you can see he is willing to use non-traditional creative ways to solve a problem.The Amadeus when it comes to market should be an instant classic and we think truly a product that redefines the category. Not at just the lower price points, but at any price level in terms of measured performance. The most important design consideration though is for it to be affordable. It won't do any good to have the best performance if the average guy cannot afford it nor learn to use it.
From experience, MDF is not a good platter choice. I mean just look at the platter choice of all the budget tables - P2, NAD, Project Music Hall(?) - lots of MDF that vanishes when the price tag goes up. On the other than I want to believe it sounds good because it will make my DIY TT that much easier!
The table showed was an engineering sample. It doesn't necessarily reflect what the final product will use in terms of materials.MDF was probably used for development simply because it is easy to machine, dense and inexpensive. A platter made from Acrylic is many times more expensive and departs from the design goal. We may use another material for the platter but it will have to be dimensionally stable, inexpensive and not affect the measured performance in a negative way. The current MDF platter in the engineering sample works wonderfully in regard to providing a perfectly flat, round non-resonant surface.
