My Favorite Tweaks, What is yours?

About tweaks i prefer  homemade one (acoustical one and mechanical one ) but sometimes i reach my limit ...

I am not an electrical engineer...

My best tweak after Schumann generator well located in the system and grid of Helmholtz resonators well located (low cost)

is a Chinese  set of buffer and filters for your low cost  dac and pre-amplification they gave the needed  clean power at the right time...( i recommend linear power supply especially sone low cost one from China )

I owned 3...

If your system is low cost you must try them....( i say that because i never try a 30 bucks buffer with a 4,000 bucks dac , mine cost under 200 US bucks )

Lusya technology aliexpress ...

They cost me under 100 US bucks, not for one but for the three of them , with no Tariff, and  postal cost included ...

They are stupendous for the cost ...

These are by far the best tweaks I have ever tried.

I initially scoffed at these but then in a bout of liquid courage actually bought a couple. Those SR PHTs really do make a difference when it comes to analog playback. I have the green one on my head shell and the black one at the tonearm pivot point and the difference when they're on versus when they're off is quite noticeable. I have no idea why.

Just received 2nd Apotema Materik Mains Filter. Materik #1 plugged into 1st  receptacle of balanced power supply along with the Apotema Black Hole filter. Not to be confused with the Vera Fi Black Hole filter. I will be trying Materik #2 in the wall receptacle of dedicated line to see how things sound. While auditioning these filters from Italian company Apotema, I have removed a handful of Purons & PS Audio's Noise Harvesters. For anyone unfamiliar with Apotema's offerings (Not well known in the States but enjoy a fine reputation in Europe) my impressions will follow in a few days.

My last tweaks is not homemade. I bought very low cost Chinese linear supply and buffer +filters for them..

Great upgrade for three bags of peanuts...
