The Most Cost Effective Tweak


What is the most cost effective upgrade or tweak? What yields the largest return on investment (ROI)? What if you could spend no money and no time and yield significant performance increases? Theoretically, that would result in an infinite ROI!

So how do you make that happen? Stop tweaking. What happens when you stop tweaking and messing with your audio system constantly is that you let everything burn in and settle down. Go read one of the many threads on this website that talks about how long it takes for components and cables to break in. The answers range from a few hours to several days. If you are suffering from constant upgrade-itis, you never let your audio system fully burn in. You’re robbing yourself of free, infinite ROI. And you never truly hear what your system is capable of. I’m not saying don’t upgrade your system. That’s a lot of the fun. Just give it some time and let your system burn in and open up. Reassess where you are at and where you want to go next.

Due to reasons I won’t go into depth on right now (mainly power issues), I am temporarily using a relatively cheap, high power, class D amp. I wasn’t thrilled with this setup and wasn’t sure if I could even call it’s sound signature high end. Due to a busy schedule, I have not had time to upgrade anything or even pursue simple tweaks. As a result of that, I have witnessed how the amp and my system have burned-in/settled down - whatever you want to call it. The sound was initially on the thin side and had harsh treble. Now the soundstage has become huge and the sound has become very smooth - smoother than I thought class D was capable of - especially from a class D amp that isn’t really something to write home about.

My point is that I realized significant performance increases by doing literally nothing. And now that I am hearing what I believe is the true sound of my system, my next tweak or upgrade will be more effective because I can clearly recognize where the weaknesses are at instead of making judgements while things are still burning in, which is often the case with upgrade-itis.

My SS Rowland Model 12's have "stand by" power mode. So they are always a bit warm. 

My SS Rowland Model 102 and 201 have been on since I installed them in 2009. 

My Rogue Ares Magnum tube phono preamp has an on/off switch and it is to be turned off when not in use. 

Most cost effective tweak? Not sure yet. Might be the NPS 1260 I'm about to use. If cost is relative, Townshend podiums? Or pods under my amps etc?
Surprinsingly, two of the cheapest tweaks that should be prioritize are often the most overlooked as we are all always looking for upgrades...
1- Speaker positions, away from back wall and surrounding walls, toe in, tilt.
1.1- Speaker grills on or off, most often off sounds better
2- Your listening position in the room
Dial this right, and the performance will be significantly better.
I’m surprised that no one has mentioned ac recepticals. It always kills me when someone plugs a $2,000 power cable into a 99 cent receptical. After spending $10,000 to $100,000 or more on a system a few hundred dollars in a really good ac receptical will make huge improvements.
