Old thread I know..

I was wondering what brand of OPA you guys are using, and where you purchased them from? eBay?

Thanks!!

Ok I did order BB OPA637's was hoping for a little help on other upgrades for this unit, I did do the MR CC's a couple years ago..

I did read where someone upgraded the wire with tone are wire don't remember if it was kimber or cardas...
