What are you tweaking this weekend?

Round about tweak

First, when feasible, I take the covers off my gear, as with my Voyager GaN350 and (and my EVS 1200 before it) and my Oppo 105. I also have/had a Marantz HD CD-1, used as a transport. It started making scratching sounds, so I opened it up which included taking the cosmetic side panels off to get the top off (much like a chinese puzzle). Anyway, I was unable to solve the problem, as it needs a complete new drive mechanism ($150 + shipping, so bye bye), BUT, when I put it back in although I didn't fix it, it sounded like a much better transport, stunningly so. YMMV, but if you have a HD CD-1 I highly recommend stripping it down 

On a positive note, I am replacing it with a virtually new Audiolab CDT 6000

What most people ignore about SMALL room acoustic is that any change that affect the listening regular position affect also ALWAYS the nearfield position in my case 3 feet from the speakers....

I learned from my experience that the most easy to control room are small one like mine , 13 feet square, 6 feet 1/2 which claim many people will contradict even some acoustician...The room is hard to control at first yes they are right, but at the end give the better S.Q. for my 2 positions...In a room the double of it it will not be so easy for 2 listening positions at all..

Another supposed fact debunked by experience, square room are bad yes, but you can cure them and even take advantage of this...the bass for example of my 7 inches speakers drivers Mission Cyrus move my body and almost the wall IN A 13 FEET SQUARE ROOM...I disconnected my only Kreisel woofer long ago...

Acoustic is the sleeping princess, the pieces of gear are only the seven dwarves...

Kiss the princess not the dwarves.... 😁😊

Dont listen your amplifier, listen to the room..... 😁😊

Am i the only one who understand acoustic WITH HIS EARS and dont give a damn about an upgrade at any price? No it seems audiotweak know that also , he is the only one that give me an idea....And the OP yes if i remember his posts...

I made my last upgrade this evening with empty paper rolls...

Think about that...

Some Idiot which had never read about acoustic mocked me many times and i decided never to post photos again.... And when this someone give me a "tin foil hat" the same sheep consumer dream probably about 100,000 dollars amplifier..

This world is crazy because freedom is ignored and knowledge too....

Knowledge is not science and no, science is not technology....

I'm tweaking the setup of a beautiful refurbished Sota Sapphire turntable and Hana ML cartridge a very good friend sold to me. He's a member here. I'm having way too much fun!

SOMEBODY STOP ME!!!!

The results are very good...

Acoustic is indeed the sleeping princess.....

I already figure it out for the multiples tubes and already juste made it...😉 it work...

I already used Helmholtz difusers with pyramid of closed tubes but you suggest to me something new: using them near my listening position... Modifying the waves flow there is crux....My soundstage is better than ever and the listener envelopment too.... Few minutes of work.... Thanks for the suggestion...but open tubes with a funels inside will work too... i will experiment...

I used a wood screen with diffusers and absorbing materials ans reflecting one in some ratio...The screen is  inclined in a certain angle behind my chair and this concentrate the soundwaves.... It is like listening headphones but the sound is in the room but at the same time near me.... I will never use an headphone now for the rest of my life....

Thanks...

You can make them all work in 1 general direction. But won't tell you for now. Tom

Better yet is to try many small tubes inside a larger tube,all are open ended. The total diameter of all the tubes must be sealed as if they are one. 

Tom

Thanks i already tested some tubular smooth cylinders around my listening position...

Open at the 2 ends...

It is modifying the laminar flow of air around my listening position.... The image is better and the listener envelopment is better...

I will make them better if i could add a direction for the flow with some funnel inside each tube at each side of my listening position, and in the opposite direction for each pair of tubes...To help EACH one ear for the first wavefront coming from each speaker... Has principle...

cost: peanuts...

Mahgister,

The visual idea is to remove or work around the interference in front of your listening chair. Provide materials that have low shear velocity but are smooth not rough. Move air to you from behind the scenes..That’s all for now, run with it and see what you can hear.

Thanks for the cues....

We don't judge here.

Sorry Erik...

Misread your OP and thought you posted twerking.

Wow, some of you have been really ambitious this weekend!

I replaced most of my AC outlets in my listening room and that was enough work for me!

I finished my room and mechanical, electrical and acoustical controls months ago...

But Alas! you just submitted to me a new idea :

Assembled 4 more LAMINAR CONTROL DEVICES. My additional prediction as to placement was a mixed bag. These placements raised the soundstage too high and placed an acoustic tail over and behind my head. I already have one on the top of each speaker and 2 at chest level on my Sistrum Rack.

I then added 1 each on the speaker stand near the floor level and another directly on the floor at the speaker center.

The ones near or at floor level increased bass clarity and probably reduced interferece from the carpet piles. The ones on the rack and speaker added clarity like a comb filter with no additional brightness just more texture.

Next will be to add 1 to either outside edge of each speaker or if this is a negative place these same ones on the floor.Simple device with easily replaceable and removed results.

I tore all of my wiring out, moved my rack 4 inches more out from the wall for better access, added some box frames to the back of my shelves to support my cables, moved the Puritan to the back wall and off the shelves, removed all my grounding boxes, and replaced all my DCCA power cords with Verastarrs and Puritans.

I have a Purple fuse coming for the amp and an ADD-power Wizard as well.

Have a nice tweakend!

Life is short, wear whatever makes you happy.

I reconnected my HD CD-1 a couple weeks ago, as a transport, after maybe 2 years and it plays fine, but a couple days ago I noticed a scratching sound, so I took the cover off (a lot like a chinese puzzle). Directly on top, there’s a metal disc connected to the spindle over a metal plate/shield. This disc is coming into contact with the metal plate but should be ~ 1mm above the metal plate directly below it, but it scrapes on the plate. Probably deeper down it’s now off center, which would likely require a new mechanism

THE GOOD: After applying a little WD-40 under the outer edge I put it back in my system sans cover. I am very, very, shockingly impressed with how much better it sounds without the cover,

@theaudiotweak 

Good luck with the laminar flow devices.

Just do me a favour. If your tweaking looks like it will destroy the space, time continuum, let me know so I can open up the bottle of Margaux I've been saving.

I was supposed to reconfigure my listening space a bit to get a little more space for everything and also tidy up the cabling for the bass array.

But, that was before I decided to cook a Korean dinner for my ex, my sister and her ex.

Love that Seoul food.

Nothing! The wife is around! 🙄

Buffer:

Does the sneaker now run like her nose (enquiring minds want to know)?

DeKay

White GoGo boots, fringed Teddy and a rotisserie chicken for my significant other (it’s my B-Day weekend, and yes I am THAT GUY).

DeKay

My wife sister add Nobsound to her sneaker.

That's more than uncanny.

@nonoise That guy looks like Peter Garrett from Midnight Oil.

I stopped tweaking after seeing this:

All the best,

I just finish tweaking my SVS SB16 subs and reading thread about Raven and PrimaLuna 

So I meant to replace the 2 outlets that flank my stereo.  Turns out I did 5.  More in another post with pictures explaining why.

I am really not paying attention to my own typing anymore.  😀

I meant to say it doesn't have to be DIY, but any change.

I just tweaked my whole system with my new Belles Aria Signature preamp which arrived yesterday. No small tweak 😁

i gave up meth in 2017

Waiting for my new power block then I will do some cable organization.

In the mean time installing new data acquisition on my Aprilia RSV4R.

@erik_squires ,

well in that case, I did dust my entire system, speakers and audio rack. Just like when you wash your car and the car seems faster, my system sounded better than ever.  It’s like a layer of dust was removed from the glass window😇

I just got an Innuos Reclocker for my Innuos streamer.

It seems to be money well spent, so far.

Bob

@stereo5  It doesn't have to be new music.  Just any change to your music system.  It can also be a new bottle of liquor you plan to enjoy with it tonight. :)

Hi Erik, Just experimenting, no conclusions yet, I’m tall..speakers are Dali Epicon 8..I have Dali and Pass, your faves...Pierre at Mapleshade always said we sit too high. he had a method of sitting on phone books, adding one at a time until "perfect" height was reached...between Covid and -10 wind chill...seems like a good day to play around with it...I know already it clearly makes a difference...also setting up a refurbished Yamaha T-2 tuner in office system, sounds great...

Maybe my wife’s nerves. Will tweak the music I listen to, not the same thing over and over. The hifi itself is quite tuned in the way I like it at the moment.  Hope I don’t jinx myself by saying that. 

Nothing, no DIY for me. 

@jl35 Interesting, what speakers do you have?

Sometimes I find myself liking below the tweeter axis a lot more than on it.  You?

Height of listening chair

Will be adding more laminar flow devices to enhance the flow of air and music  over and around stationary objects. These devices with or without an active generator make for a noticeable improvement in focus,tone and texture.

Simple and effective way to remove boundaries and move walls and ceiling further away from the listening room.Tom
