Thank you Tang. Absolutely beautiful addition to the system! Can you tell me what is on the back wall behind your head?

I am just a dumb audiophile who know no technical stuff Jeff. I just know how I want my system to sound. So, I had my acoustician sat, listened with me and I pointed exactly where the abnormalities were in particular section of instrument being played, cymbals, triangle, piano high keys, etc. Those were pretty much high frequency reflective distortions from glass windows. (This was after I identified that my absorber panels were sucking out musical info.)

I do not think there is enough discussion about how information on recordings is lost somewhere along the way. Life, resolution, harmonics can be there and removed by things we do without knowing it. We tend to focus on things being added like certain artifacts. Sometimes it is better to do no harm.

Tang, I read this and think I am reading my own words about discovery. As I reflect, I now realize just how little I know, and how much there is to learn. I feel like I am throwing everything out the window and starting fresh. Gear seems only a small part of it, and yet, gear is what we all talk about.

Ked's visits and reports and videos are about gear, and great recordings. I would love to learn what observations he has made about set up and its role in the overall sound he hears from his audio travels. HIs travel logs are too focused on equipment and compares. They need some diffusion to get the bigger picture.

When I had speakers I used to change toe in and position all the time, had laser to align them, tried GIK on and off and various passive isolation. It bores me now because positioning is very room and set up specific and your toe in position, for example, cannot be applied to tang or the other way round.

I have been to many treated rooms, including a few SME rooms (three complete, some partial). I actually liked Mike's room and Marry's room and realized that treated or not, rooms with good acoustics are naturally big and anyway sound good.

The only small room with good acoustics I heard was jazzhead's. Personally I want minimal treatment in mine. Usually it kills sound, which is why what Tang has achieved seems impressive.

I also realized one speaker at my place was off level and changed my flooring. I don't want to do this audio shit in my room next time. Imo it is silly. I want to plug and play. I am a guilty audiophile. I don't want to be one. At least, not daily at home. My horns will have minimal positioning management. I am sad tang achieved this as now I might have to try it at home whenever, I did not have this itch before listening to this video

In fact there is plenty of information on the process of stereo recording and reproducing sound. - great books, sites from professionals and amateurs and interviews with very knowledgeable people.

But surely in WBF we focus on our particular preferences and understanding them, and sometimes we can't avoid comparing them with others.

I liked the character of the sound in both of the recent videos. The second one achieved a more penetrating but sweet midrange and upper midrange that was friendly to the instruments. Different music might want one or the other, but the new paradigm works well in the YouTube-o-sphere.

I listened to them this morning and I like the sound (the music) from both...nice piece.
The immediate difference without any challenge from my part was that second music video appears louder. Or it was or those panels have that effect.

Thank you Tang. Speaking of adjusting angles, those slats on the right look to be about 45 degrees pointed down. Have you experimented with different angles or even pointing them up to the ceiling? How much sound gets through to the glass may be audible. Just curious.
Window blind up or down doesn't really make any difference that I could hear. To be frank I close it because my brain is telling me the glass is so reflective not my ears telling. My office is in a pretty quiet neighborhood so no sound coming in except when pigeons chirp right next the other side of my window...natural sound :). Changing it to a solid wall probably improves sound to a certain degree but I leave it as is because I want to let the sun in. A lot of compromises in my room because it is an office.

Sunlight is overrated :rolleyes:
I recently covered half of my 4,5m glass sliding doors with 5 inch mdf,
2 windows where’s fitted with mdf
shutters ( disguised as wall posters)
years ago. Maybe I will end up replacing the 3 layer thermo glass
with solid brickso_O

i miss my view; but not enough to compromise my sound.

in 2010 i removed some front side wall floor-to-ceiling bass traps, and replaced them with Quietrock 458 sheetrock + 3/4" finish grade plywood to better establish solid room boundaries. it worked. at the same time i did that i had my contractor build two window insert sandwiches of that same Quietrock + ply for the windows. for a couple of months i tried those inserts in and out but could not hear any difference. so i stored them upstairs and enjoyed my beautiful view and sunshine.

5 years later i was a third of the way along doing my room tuning and figured it was time to see if the changes i had made altered the performance equation with the window inserts. they were up and to the sides of my rear wall, behind the speakers, and only 36" x 20" in size. installing the inserts and listening; it turned out those inserts filled out the wrap around sound stage (eliminating holes i had not realized were there) and solidified and refined the bass. i think that was a key move to get my synergy for the highest energy music. the room is not fighting itself anymore.

now 4 years later i have not even considered removing them.

keep your mind open and your powder dry.

I think natural light is underrated. You couldn’t pay me to cover the windows in Tang’s office. I’d put a diffuser up behind the desk and be done. (And microstrip problem fix) That type of glass along with extremely limited frequencies that don’t fully get projected forward is just a non-concern. My brain doesn’t worry about it with setup like that.

My MBL’s really like a solid wall behind them, and the windows where
just in the way:rolleyes:, the mdf shutters
are hinged and can be opened.
The view of a couple of trees and
a field never rocked my world anyway. I only open them on
hot days with a lot off playing time.

I trust your room is already good. What you need my friend is a bath tub or shower every once in a while after a long listening session. :D

In Denmark we only bathe once a
week, it’s a principal :eek:

Storage shelf for vinyls, tapes and things. I have vinyls everywhere though.

I can't but notice the floor pump. Are you a cyclist or is this related to an air bearing?

I totally understand this! The glass would bother me because it just HAS to be causing unwanted reflections (even if I couldn't hear any)!

The only thing audiophiles cycle are the same arguments. Same arguments keep getting recycled on forums

Are you suggesting all reflections are bad? How much reflection do you expect when you have horns? And why do you think glass must be worse than something else? I'll remind you it's safety glass.
