Best Stereo Upgrade Value


A question for you audiophiles...

What "upgrade/change" has singularly given you the biggest (not incremental) improvement to your stereo system?  Upgraded amp, pre-amp, tubes, room correction unit, subs, connectors, cables, speakers, streamer, stylus, speaker placement, acoustic panels, etc.?

Recently, asking myself this same question caused me to review my favorite source/input device. I stream and listen to CD's far more often than any other including my TT

I upgraded my stand alone DAC with the Denafrips Venus II

I had never before updated any input source with this kind of result. Gobsmacked I am. Great product. Great upgrade.

Mark me down for speakers.  They should also be the most expensive component in your system.  Ultimately, it's the speakers that you are listening to.

It always depends on goals. Set percentages can be a guide but those percentages can shift wildly depending on overall budget. I’m presently (waiting for new speakers) listening to speakers that represent 5% of my total system. Many might listen in my room now and wonder why new speakers? LOL, they might be correct.

fully recapped amplifier with the best possible caps which only found in a very best expensive amps,since then I started to examine internals of amps

I'd probably agree with every single post on this thread dependent on exact time and situation of system at that time, this means weak or squeaky link gets the grease.
