No, in fact I learned that extracurricularly. Only from the best, yours truly. 😉
You're having dinner with SY and Jan too? 😱
Simply untrue, unless by "no effect" you actually mean 'some effect'. Unclear to me whether your sentence contains a mistake in English or electronics.
Well, explain it to me then, and everyone else.
The ferrite loop antenna has a rather low Q, and covers more than the entire broadcast band. The typical AM signal is ~20kHz wide, aka +/-10kHz (before the stupid IBOC debacle) so how is the Q going to effect anything other than the effective sensitivity of the antenna?
it's the receiver's IF shape that is going to effect the bandwidth.

With RIAA feedback slew rate of MOST of modern opamps is plenty. Something else may be different that affected the sound.
Good luck convincing him otherwise.
RIAA is passive.With RIAA feedback slew rate of MOST of modern opamps is plenty. Something else may be different that affected the sound. Non-linearity of an output impedance?

Why do I need to convince anybody? I am happy with my console that I made from TOA RX-216 with almost all opamps left 4558, biased by 7k5 resistors from outputs to + rail. I should bring it to BAF instead of a small one I brought this time...

I perhaps should say, a number of us tried to impress that line of thinking and it was stonewalled. I'm glad you have a working console that you enjoy!

I think he actually can albeit at the psychoacoustic level. Signal level (volume) and S/N can both alter your perception of the tonal balance. Assuming that his manipulations are altering them, we could have an explanation.
But psychoacoustics are a non grata subject here, let's make place for the THD polishing programme 😉

Speaking of Q of antenna, it affects a mirror image selectivity. It is the example of barking on the wrong tree. ;-)
I'll try it. it will take me about a week. Isn't the 4558 is going to have a problem driving a 600 ohm LCR network though?Why do I need to convince anybody?

Most recording desks don't show opamp differences easily. The long power supply lines and all the cables with all the switches, molex... eat up what a nice opamp can do. In fact this is one area where the grunge of a device will give something to push through the myriad of stuff in a desk.

I appreciate your efforts, however the selectivity loss was already covered under the concept of "noise"?
Did you notice the name of this forum?
Interesting question. Yes I did. And thanks to the centuries of real Physics and Engineering experience on here there is a whole thread dedicated to how to install and use LTSpice. There are also lots of discussions on how to layout PCBs, how to measure and build some fairly advanced measurement rigs etc etc.
Some of the stuff discussed on here is close to SOTA. Way beyond what you need, but technically superb.
So yes, this is DIY, but not DIY as it used to be. People can if they have the right mindset learn a lot... or they can randomly change components. All types are catered for. Certainly if you don't learn something on here you are wasting your time.

Great points, but I wouldn't expect much of a response. Unfortunately, there are a number of people here that are proud of their technical ignorance.

.
Perfect opportunity to play with a BUF634?

Probably. For outputs I use different opamps.
By the way, here is the sound of my console with bunch of biased 4558, and my line arrays:

oh boy...
Anatoliy, I like you and you design some very good and interesting things.
BUT.
Unless I saw it wrong, ur running quite a few Behringer boxes?
Kinda obviates a whole lot...

Overall nice sound. Vocals a bit strained and squished, but over all nice. Only nice though, not jaw dropping.Probably. For outputs I use different opamps.

Bear, I have the connections to possibly get a visit.
If that's an invitation, yes, I'd do that.
Would be an honor and a great experience.
You could email me or PM, etc... or contact someone else who has my info, ur PM box seems full up... or if yr old AD email is still alive, I could email you there... of course if ur saying that you could get a visit for yourself, that's another matter! At least take pictures if that's the case.
_-_-
You would have me take out one gain stage the works very, very well now and replace it with a device that is basically relegated to guitar stompboxes and then add a buffer stage as a crutch for the stompbox stage device? C'mon man!Perfect opportunity to play with a BUF634?

Unfortunately Dick is in his 80's now and I don't know if he still has an occasional demo. It will take a while for me to ask around.
