I was unaware of Fritz speakers until pretty recently..maybe 3 or 4 months ago. There was not a ton of info or user reviews on the Internet but what I did come across was all positive. This forum had a lot of good words to say about them.
It is the quality of drivers that he uses which really sparked my interest..& the not ridiculous prices for a speaker that uses that caliber of drivers/tweeters. Outside of some DIY tube equipment most of my audio purchases are from the usual suspects of mainstream equipment. Other bookshelves I've owned over the last 3 or 4 years are the Linton's, R3 Meta's, Elac Vela 403, Martin Logan XT-B100.
I came across a used sale for the Fritz REV7 SE. The price was really good so I took a chance..bought them without listening first. I am very impressed by their sound. They have a clarity & midrange that is sweet. Vocals are very nice. Guitar strums, bass plucks, the attack on drum hits & shimmering symbols..all extremely realistic. They disappear very easily..even in my wonky room. Putting instruments & sounds out into space all around the speakers. I know that some of this might sound a little ridiculous or overzealous but it is truly what I perceive & hear when I listen to them. They do seem to have just a smidge more emphasis on the upper half of the frequency response. Or maybe I'm just not use to a speaker this open & easy sounding.
So I am a fan now. I did reach out to J.Fritz after my purchase thru email. He definitely seems like a cool guy. Very personable & open to talk about all things audio. He encouraged me to give him a call as I wanted to know more about his other speakers & designs in general.
