May be he can provide a picture of his system , that would at least be something

I am still awaiting delivery of the Transducers that I ordered from you Serial number 002 I believe you said

You ask we deliver .
I m making a " budget version " , 2 * 8 inch bass hexacones , paper mid ( and possibly carbon fiber mid ) top notch soft domes .
Ultra hard composite housing for under 10 K at the dealer / consumer price .

So delivery sometime around 2036 by your previous track record

A Neptunian Summer then !

Still a lot sooner then seeing a picture / vid of your system

Will that reassure you ?

Not if you only have a transistor radio

It is certainly not about personalities. I'll elaborate later, for now, some recordings of this annoying song...
My system is a work in progress, I have my own thoughts on its limitations, and all constructive criticism is welcome! Fire away, but remember, we are all "audiophiles"!

First video is taken from my listening position with my Tascam DR-100 MKIII recorder and Superlux S502 microphones.

Second video is taken with the microphones placed 1.2m closer to the speakers, and the speakers toed-in slightly more so the microphone diaphragms are in the speaker axis. Since the mics are closer, I reduced the volume by 3db but made no attempt to volume match the two recordings.

Are the use of better microphones of any interest here ? I think so - the frequency response of the microphones don't alter as much the sound. My phone's build-in microphones are terrible and I see no point in making a comparison video with those, you can just take my word for it. I don't have an iPhone! With all these microphones, however, the bass is probably rolled-off.

Does the change in the microphone placement have any effect ? I think so too, but that will depend on the microphone used, the way the speaker interacts with the room, and the way the listening position is "acoustically" optimized or not.

As you can see in the link below, these Superlux microphones are angled at 110 degrees, and from the listening position they are not facing the speakers. I am going to assume that the way they interact with the room is different to our ears (and that is the case with ALL microphones) - which setup is more representative of the listening experience ? I don't know... There are other variables at play, so there are probably some pros and cons to each setup.

I rather think that it has to do with the radiation behavior of the driver. In the second video, the brilliance and presence range of 3-8 khz is somewhat reduced, I like it more. the voice appears clearer and fuller with more body. is my opinion on it.

Oh Go on then … I didn’t wish to embarrassed Little Old Carlos given his state of mind over his stuff … we got a great deal on some cables sourced from some closed down facility in Russia !

Even musicians compare equipment on YouTube !

I wonder what microphone she used

Check out the comments, no one is claiming video comparisons are BS!

Will and hopkins what kind of texture and bite do you hear on this cello comparison video? Just want to see how your listening system reproduce the texture and bite on this video and how texture and bite compares to the other videos on this thread. I hope that you hear my point that I’m trying to make here with hopkins’ own video here.

 

[Ron Resnick]

Way better ways to test female vocals, classical or otherwise

Testing for what, exactly (so I can understand what you're talking about)?

 

[Ron Resnick]

On all the other videos, posted to this thread of this recording, the double-bass could easily be mistaken, and it obviously has, for a violin or a cello because of the systems’ lack of really deep and full bass reproduction capabilities.

The fact that some of us audiophiles, including me, don't know what a particular instrument sounds like is not evidence in support of the veracity of a particular stereo system behind one video or another.

because of the systems’ lack of really deep and full bass reproduction capabilities. the tone & deep and full character of the double-bass is loud and clear in the room.

I think the David/Tang video at least equals any of the videos for "tone & deep and full character of the double-bass." I may quibble about what I perceive as the resolving power of that system on vocals, but I tout relentlessly the competence and believability in the 50Hz to 500Hz region of the Bionors, Tang's speakers, and Peter's Vitavoxes.

I thought your SET/DHT system video was fantastic!

Ron, as usual, you managed to miss the point of my post. You are going to need more than 8” drivers to play with the big boys!

I was looking forward to adding big subwoofers to my system. I've been talking and plotting with Lloyd about it for years.

To my surprise my frequency response is literally rising slightly at 20Hz. And after I tamed most some of the 45Hz and 60Hz room boom, I was able to raise the woofer tower level up to -2.5. This leaves me 12.5 steps to go in raising the woofer level further.

I would love to be able to talk myself into some practical excuse or some theoretical excuse for adding subwoofers to the system. It wouldn't take much, I assure you. But this woofer tower system with a 1,000 watt Gryphon Class AB amp has derailed my big subwoofer plans.

 

[Ron Resnick]

Can I just say . . . cosmopolitan quibbles about rarified audio preferences aside . . . that almost all, if not literally all, of the videos posted here reflect systems which likely sound amazing in person, and which would be a revelatory experience to any civilian outside of the hobby!

 

[microstrip]

Number 1 perhaps? They both look kinda rough, but number 1 has a smoother roll-off response in the higher frequencies.

You preferred number 2, as I could expect. There is nothing in the general trend of the spectra that could justify a preference in such low quality media, but we see that the spectrum no 1 is much more ragged, showing sharp discontinuities that should not be expected in real music of this kind. Look for the sharp discontinuities in the band up to 2kHz in spectrum 1 and the nice plateau between 4 and 10 kHz of spectrum 2.

Small spectral changes in particular zones can completely change our perception of recordings. It is why I am always skeptical of such videos - the position of the microphone of an hand held iPhone can drastically change the sound quality of the recording.
