What happened to diyaudio?

I've also been away for a time (approximately 4 years). Yes there are some threads which go on, and on, and on (like this one apparently is heading in the direction of). Yes there is the perpetual posting (from both sides) trying to convince the other side that they are wrong (faith based vs science based). IMO if it bothers you, tune out!! There is no point trying to convince someone of something that is not within their version of reality. By all means try if you must, but if it doesn't work give up already! (this goes for both sides of the fence).

Maybe we should close all threads with the objective vs subjective discussions. They have been going on for half a century. (Ps. I refuse to call it science based vs faith based). Because actually a lot of the so called "science" is faith based and visa versa.

I like the use of subjective vs objective 🙂 Yes I guess that the so called scientists/engineers have faith that the fact that they know of no measurements that can demonstrate a difference, means that there is no audible difference 😉

Days and sometimes weeks pass in valid project threads without a comment, positive or negative while these threads grow and grow.
It's somewhat ridiculous really.

Discussion is good. It does seem to not find a common ground though. If these threads that you mentioned are so worthwhile, then why would people that were interested in them not comment on them? Sounds to me like people do not find them worthwhile or simply have no interest in them for some reason. How is that ridiculous?

Right, that's exactly my point, there's no reason for me to enter into this discussion if you seem to think that the laws of physics and mathematics that govern the operation of the equipment you use for audio recording and playback are based on 'pretty crude models'.

The only factor that we cannot quantify exactly is what happens between the ears, the belief system, psycho-acoustics, reputation of a product, word of mouth, etc. etc. That's why a proper DBT shows no differences between all those overpriced cables and a piece of standard copper installation wire. When you take all the nonsense that is belief and reputation of a certain product out of the equation and judge it on its 'sonic signature' (for lack of a better word) then suddenly it all sounds the same. Given the fact the listener is the only variable in a proper DBT what does that tell you? (of course the believers will argue a DBT is flawed, so we're going to go in circles).

Cheers,

Physics cannot describe the human mind when it comes to sensation for a simple fundamental reason: the human mind is not time-invariant.
The human brain always makes a selection - according to unknown criteria - of the information you give it. It is never exactly the same from time to time and form place to place.

Time invariance is the basic hypothesis to apply the Fourier analysis.
The Fourier transform relates in a unique way time and frequency domains and that's what you get from measurements.
Unfortunately all this stuff has little utility (can just be useful to find the "right" direction to follow at the beginning) when you include the listener in the chain.

Medicine is science however it is empirical. The science of musical sounds is the same. Science has just one requirement: the scientific method (that is based uniquely on the observation of phenomena). It doesn't need formulas at any cost!
In the end music has been created empirically: try, listen, adjust, try again, listen again etc....

Cheers,

Considering the venue, what have you built lately?

I am building a set of tube mono block amplifiers, with separate power supply chassis for each channel. Tube regulated bias supplies and power on all stages, except the output at the moment. I hope to start building the cabinets for a pair of Grand Ekta speakers designed by Troels shortly in my wood shop also. Is that OK with you 😀

Quite a while...2 years. Maybe less less yacking and more whacking is called for 😉

No this is a totally different amp if you would have read my post. I shelved the initial mono design and built the KT88 amp as a stereo amp as it was my first scratch build. It was not as good as my commercial amps, but I learned a lot about wiring the chassis.

This a completely new design with mercury vapor tubes (866A's) and separate filament supplies for each stage too. It is a lot of work and yes I probably should spend more time in the shop, but with the Texas heat, I only work in the Fall/Winter as a rule. My wife would not allow me to work on any of these projects in the house.

My point: It's a shame to see threads come and go with next to no attention, no comments (it wasn't like this early on - lots of old threads had tons of comments over short periods of time) while these "useless" threads flourish. It's not my idea of the DIY spirit.
Too many here think that DIY is to go buy a new cable and attach it yourself or debate the subjective versus objective viewpoints. This is not DIY.

On this point I totally agree. I sincerely appreciate all of the efforts that the knowledgeable share with others in these forums. I have gained a tremendous amount of understanding from reading these forums.
