GM from NJ. Selling air and rocks ... genius! Washing machine pucks and tack are a big part of my system. I have space limitations in my main living space, so your advice on what to buy is spot on. Thanks for this, very useful my friend. btw ... the echo of children lasts for the rest of your life. Four kids ... all adults, only two left at home ... and I can't block them out - ever. And then there's the wife ... Great vid!🙃

Love your channel, Matt. I can't wait to hear your take on the new Emotiva speakers. Months ago I took advantage of their clearance blow-out sale and picked-up their C1+ CC and a pair of B2+ stand-mount speakers which are being powered by an Emo BasX A3 amp. I'm anxious to hear your review on their new tower speakers, namely the XT1 and XT2 when they become available as I'm hoping the XT2's will become my end-game speakers.

Great video! You are the most helpful!

Good deductive reasoning in this!

In audio…the perception is the reality .
Have a great weekend.

lol! This was pretty hilarious and awesome. Call me a fool, but I actually noticed an improvement when raising my cables with wood blocks. But might just be they’re getting a little dampening from my seriously resonant - might as well be a giant passive radiator - wood floor. Something cool I tried for a small listening space was to replace the closet door behind the listening chair with a curtain, effectively increasing the room volume while providing some no cost bass trapping when leaving it open (sheets, pillows, jackets etc.). It actually worked. Finally, those cheap Nobsound spring pucks are money well spent🔥 👍🏼🙏🏼

Great video, thanks a lot, i didn't how critical were the pebbles in front of my house for hifi....just start singing them to get some money for a new sub.

Yes!  The pucks totally work.  I use the furniture moving pucks under bookshelf speakers at home.  At work, for desktop speakers, I use pieces of Styrofoam.
For dacs using a USB phone charging block, try plugging into an unused USB port on a tv.  I think my Modi 3 sounds noticably better powered that way.

BDR Cones... Mk3 & 4.

Fun video, Matt... and right on point....

Listening at night ... Air density is slightly higher in the cool of the night. Sound travels better.

Speaker placement ... moves as little as 1/4 inch can make a huge difference.  Make sure the distance from your sweet spot to each speaker is identical.  Equal distance is more important than actual distance.

To be avoided ...
Very expensive versions of things with the same features.  Price is NOT an indication of quality.

Nice vid. For under standmount speakers I like Moongel pads, which are made for dampening snare drums etc. Slightly more expensive than Blu Tack but does a great job.
Under subs I like SVS Soundpath feet. Again, more expensive than washing machine pads, but I have tried both and the SVS feet are much better and still will not break the bank.
Ikea chopping boards are perfect as equipment stands, with sorbothane feet under them. A great tweak.
Lastly, Darko came up with putting metal doorstops on small, desktop equipment to stop them moving round. It works and you can take pleasure in your friends trying to work out what the hell they are.⁸

The midrange rock had me rolling!  It makes me wonder what the size and shipping costs would be on a subwoofer rock?   Also, like with the battery wires, do they have passive and active rocks?

I tried cable risers a while ago. They didn't make any difference. I then upgraded my speakers and amp, but didn't bother with the risers. After watching GR Research's video on risers, I tried them again not expecting any difference.
I was shocked at the improvement. Even my wife who has no interest in audio commented on how good the system sounded. I have a dedicated audio room with acoustic treatment, so YMMV.
There is a video on YouTube which may explain why this happens. Apparently the latest research indicates that electricity flowing through a wire doesn't act the way we once believed. It has something to do about the energy field that surrounds the conductor. You should be able to find the video if you're interested enough.

I use a headphone tube amp as my stereo preamp (daisy chained). Kills any shrillness.

Thanks for the video Matt! I just pulled the trigger on those Sorbothane isolation feet for my Zu speakers. If anyone orders these, make sure you purchase the correct ones, they come with different weight ratings. The 30's will not work with a heavy speaker, you will want the 70, they come 8 to a pack. I have the SVS iso feet on my two SB3000 subs and they did make a difference in the bass by getting it out of, or decoupling from the floor. Now, my Zu speakers are beyond stupid with the bass, and I want to see if these help with the same issue. Thank again Matt.

Network streaming, sometimes just a reboot can improve your audio, it may say 100mb download speed, but what's in the download speed ?  a reboot sometimes just cleans it up .

hi UK here,  need an inexpensive power cord  get yourself some UK rated kettle leads (£6.00) they can handle 240 v & a healthy 3kw of power = 12.5 amps more than enough for the hungriest component. the wonder of being able to boil enough water for 2 cups of tea in under 60 secs   imagine what it could do for your system.

I know most will think this is classic snake 🐍 oil. I heard about a break in cd from Arye Acoustics a reputable company. I checked into it and bought the Cardas-Ayre cd from Amazon for $36. I had doubts but kept a open mind. I played my main reference cd Larry Carlton Discovery and while listening I had the feeling of needing to turn my sub up just at bit. So then I played the Cardas-Ayre cd through my system at average volume. Then after I put Discovery back in and no kidding I didn't feel the need to turn the sub volume up anymore. It really opened things up and to my suprise 😮 it worked. I don't believe it's snake oil on this one.

You mean I wasted my money when I paid 60K for a pair of Nordost Odin Gold speaker cables? Darn it!

Great vid, some suggestions. 1. Equilateral speaker/listening positions are fine but once you've done the initial setup, move forward & backwards with music playing to determine the BEST listening position. 2. If the speakers are located asymmetrically in the listening room it's much harder to minimize bass room modes. 3. Equipment displays are a distraction & pointless because generally the're not readable from the listening position. 4. If you make your own RCA cables make sure the cable is good quality (low capacitance, shielding, low microphonics) & the connectors have good quality plating (clean the contact surfaces every couple of years to remove oxidization etc). 5. If you suspect your system is subject to AC interference, try a common choke wrapped on AC & DC power cables. 6. Static electricity discharge into your equipment may damage it, if it's frequent consult an expert. It reset my AVR & blanked my TV for a few seconds, yikes, until I got it sorted.
