What makes the biggest difference in sound quality?

My two cents here:

1 Room

2 Speakers

3 Source

4 Preamp/Power Amp (depending on speakers, a good integrated with few watts can be enough)

5 Power cords

6 Speakers cables

You say, Teddy, biggest and baddest and most wonderfullest in my system:

LPS fitted with

Blue Synergistic fuses.

Once you get the room right, with a bunch of Ethan’s acoustic panels, it does not really matter what speakers and gear you use. It will sound fabulous! 🙄🙄🙄

Walmart $49 DVD player, kiddie ladders as “speaker” stands, etc. It will all sound the same as a $xxxx,xxx,xxxxx system

This went way better than I anticipated!
