The Schroeder has arrived

Dear Frank: +++++ " Low frequency reproduction is quite strongly linked to the quality of the rendition of upper harmonics. This is why adding a "supertweeter" often improves the perceived bass quality of a speaker. " +++++

You are absolutely right: this happen when I add my Tannoy ST.

+++++ " Over the years many audiophiles have gotten used to an exaggeration of upper harmonics, resonant arms(platters, too), bad amplifiers(often solid state, sorry) and cartridges with high frequency resonance peaks as low as 12kHz(!) being some of the contributors. " +++++
THis is one of the " audio cancer " type.

+++++ " So, should I design my arms to match well with severly flawed components? Certainly not.
It is not this "HiFi sound" I'm trying to adhere to, but rather produce a component with as little a sonic fingerprint as possible. " +++++

I applaud you for this.

+++++ " But I do saturate the armwands with a variety of oils, some remaining liquid, others solidifying over a period of three to six weeks, until they all exhibit the same internal damping properties. " +++++

THis kind of care about speaks for your dedication on the research/design/build/test process: great!!!!!

I will have to look the opportunity to try your tonearm on my audio system: I deserve that!!!!!

Tks for your time and delightful explanation about. I think that all of us really appreciate that.

Regards and enjoy the music.

Dear Thom: It is sad that Micro Seiki is out of business. The MAX 282 is only a product that speaks about this quality oriented company.

Btw, the MAX 282 use torsion bars instead the common spring for the VTF.

Tks for your answers. Always is pleasing that people like you really are on " target ", with audio items like the Micro tonearm.

Regards and enjoy the music.

Thom,you are absolutely right about getting to the ball quicker,and the shoulder turn,for a hard topspin shot.Watch Federer for the textbook look.As for me,I always considered myself an "A" player(40 yrs of hard competition),but my rackets are 12 years old.There was a time when tennis dollars came first,now it's audio,in the driver's seat.Though I am hitting a damn good ball.Just that there are 2 "biggies"at my local courts(a couple of yrs older than me,too)who can hit the crap out of the ball.On the dead run,no less.I'm close to these guys,but no cigar,and I'd love to wipe the smile off their faces,and will,in time.Just have to follow the methodological approach,that I did with my system,over the years.Take one weakness at a time.It's not as crazy as it may sound.That was my summer goal,until this thread.Now I'm thinking audio,in June.Hmm,I guess I'm going to hear that familiar "Dzzzzt,Dzzzzt"sound passing my head(what transients do you think they might be?)when I hit a crappy approach!!

Enough kidding about tennis.Frank,you have a very valid point about bass,as you clearly know.I see a trend in this hobby(look at the amount of ported speakers,and very few sealed enclosures)towards lots,and lots of really crappy(too strong a word)bass.Let's just say that many designers are happy to give the public what most people like.Lots,and lots of bass.Not accurate bass,mind you,but no true pitch definition,in the lower,or even mid frequencies.This blows my mind!!

I have heard SO MANY pricey set-ups where the average person thinks the bass is great,only to look at the expression on my audio friends's faces(very experienced hobbyists,who preach bass accuracy over quantity),to realize these people would not know a tympany drum from an amplified drumbeat,on a synthesizer.

When we are stopped at a red light,and the car next to us has his boom box turned up,do you think that guy is concerned with accuracy in bass,or overblown dreck?We all know the answer to that one.It's sad,but a fact,and many mfgrs are all to happy to design products,while maybe not as exagerated as my example,but not accurate either.

Myself,I need accuracy,as Frank describes.Makes more sense to me,and sounds better too.To the average dude,who knows what they like.I like my tympanies to "sound" no larger than a 38 inch skin,and I could care less about anything under 35 hz,although it's nice to have it,but most LP's don't have alot below that.Oh yeah,I happen to have a good sub,and would bet a Shroder Ref could do the low thing,just to my liking,wood or whatever!!

From an email sent to me from a leading setup authority:

"According to my Japanese books from 80s the Effective Length of your Excellent Arm is 282 mm (pivot to stylus). The manufacturer's Overhang is specified for 12 mm.
This is not correct. The calculations based on Prof. Baerwald formula give Ovhg = 14.5 mm. So the distance from arm pivot to platter spindle should be 282 - 14.5 = 267.5 mm."

One of the overlooked tuning features of this arm is the tightness of the dial used to hold down the arm.

Dear George: The Baerwald formula is totally right, overhang= 14.5.

The Micro Seiki manual operation specifications gives: 15 mm ( overhang ) for the 282 and 12mm for the 237 models respective.

Tks George.

Regards and enjoy the music.
