I've built the boozehound. After break in it was clearly better than the phono stage in my Carver C1 (which was better than my phono stage in a 90's Rotel integrated). Even after I upgraded the opamps and caps in the c1 the boozehound killed it. I run it off 16 AA batteries...it seems sensitive to voltage. 22-26V it's good. After that it drops in gain and SQ. I'd like to try a linear supply with it someday.

Highly recommend the boozehound. Seems expensive till you realize there are 4 matched toshiba 2sk170's in there and PIO caps.

Agreed. It definitely beats my Lehmann (early) Black Cube and Phonomena.
I also run batteries, 2 12volt SLA batteries. I've run as low as 18VDC, and I agree 22 volts (or up to 24) is definitely the sweet spot. I am still building other DIY preamps because it's fun and inexpensive. What I would like to gain, over the Boozehound, is:
*Better mid definition
*Although good bass extension, a bit flabby at times- Tighter Bass.
High end is good, but perhaps a bit better extension- a bit of rolloff noticed.

This is mostly "nitpicking", as for $90, it is already beating $600 preamps.
Not bad!!

I emailed Pavel-
Unfortunately, he is busy with other ventures right now and not producing any more PCB's. And I don't trust my skills in assembling without a pre- etched PCB. But I really like the looks of that design, with all those J-FET's it must sound really nice!
I found a PCB project on Ebay (from Israel, I believe). It uses 3 AD706 op-amps.
Not sure what the third IC is (Buffer?) but it is an interesting looking design, so for $10, I said "what the heck?"
Is anyone familiar with that model- OR the Analog Devices 706 op-amp for a use such as this? There is frightfully little on the internet about this design, Or that op-amp.

Thanks!
Gary
