These Revival Audio speakers from Daniel Emonts look slick! I'm guessing that they give KEF, Focal and Dynaudio a run for their money. You can tell that the design and craftsmanship are considerate. The prices are very reasonable too.
However, you're paying full MSRP.
Yesterday I bought a Creek 4240 integrated amp for only 130€. I say this because the seller was also putting up a pair of Castle bookshelf speakers in excellent condition with wooden stands for sale around 250€. Castle is a very reputable British speaker brand. So you have a solid amp + speaker combo for under 500€. The equivalent new would be 3000€. Granted, this is 2000s equipment, but it sounds excellent to my ears. I see another local add for Castle speakers for 300€.
So if you happen to live in France, look for Castle speakers. They're so underrated and underpriced on the used market. Equivalent JBLs would cost like 1000€.
It's a shame that Americans hype everything up. Vintage gear seems a lot more expensive over there. It's appalling that beatup Klipsch Heresy speakers go for $800 easily.
