Primaluna Prologue Classic

Don't know the dollar amount you are assigning to "affordable" but Prima Luna's Kevin Deal speaks highly of the AudioQuest Niagra 1200 ($999)

here's the link with his video assessment of it

What stand alone affordable power conditioner do you guys recommend for a Primaluna Prologue Classic. its rated 285 watts power consumption on 110vac. Thanks,

Had a Prologue 2  for 13 trouble-free years . Not so much as a hiccup the whole time .
Traded up to a Dialogue Premium...same experience .
With tube rolling it can sound pretty much any way that you want it to .
Hard to beat for anywhere near the money .

Good Luck .

Prima Luna does one thing that I can't ignore. It's the point to point wiring. Compared to practically anything else, it can last a lifetime. Also, for those companies that do use circuit boards, there are big differences in quality between one board and another. It is something to consider.

The Prologue Classic is essentially an upgraded Prologue 2. Plenty of positive reviews, do a search.

I used a Prologue 2 for many trouble free years, and went  the PL food chain to the Dialogue HP. The only possible negative no remote.

PL build/quality is on the level of top level,high dollar gear. Unless you're stuck on the "Made in USA" thing, highly recommended. More versatile than other price comparable brands.

Since sonics are subjective, I would say sound quality is somewhere in the middle(not tubey/not SS sterile) and speaker choice will get you where you want to be.

Also can be tweaked to personal taste with tube rolling.
