Just thought I'd bump this thread up for some more people to see. I have no affiliation with Five Fish Studios. just bought one of these 500 series pres from the Five Fish Ebay listing. I live right down the street from them and the price is extremely appealing, so I figured I would bite the bullet and order one. The one I ordered was pre assembled and has the optional Nickel Input Transformer. I haven't had a chance to spend a lot of time with the pre yet, but first impressions are WOW! The unit came very professionally packed and the build quality and components are top notch. Hopefully I'll have a chance to dig a little deeper into the unit this weekend. The only thing I've had a chance to run through it so far was vocals, and it sounded really, really good. To my ears this pre is in the same league as my other high end preamps. The Five Fish pre definitely has it's own thing going though, so that's cool. Like I said, hopefully I'll have a little more to post about this at the end of the weekend. I just can't get over the price/quality aspect. I'm impressed, nice product - Public Post on Gearslutz.com
