I think the Puffin/Waxwing is probably better than the equipment of a lot of purists who have mid-end and even upper-mid-level equipment. I've never owned one and never will because I have a Millennia LOCi and a very sophisticated digital processing rig, but from what I've read it's very competitve with everything under a couple grand, especially if you have any contact with older recordings such as 78s. I regularly recommend it to 78 collectors. It's a godsend for 78s especially because most of the preamps out there are total crap in various ways, e.g. not allowing for stereo, colored electronics, incorrect EQ curves. The Puffin allows for the adjustments necessary to get the most out of old recordings and has a few 'bonus features' like Super Mono and Magic. In most cirumstances, I'd take this over any 78-oriented preamp under $3k, mostly because the other options are terrible.
The new Waxwing requires you to control it with a mobile device, but I wouldn't think it would be difficult to find an old Android tablet for a few bucks to use as a dedicated remote control.
I'm also curious to know how it stacks up specs-wise with higher-end stuff. I've looked around for that information but haven't found the greatest answers.
