Don Sach's pre amp

Good topic . I have the Rogue RP1. I swapped the stock JJ's for Telefunken Tektronix, huge improvement . Also went to a Silnote power cord . I'm playing FLAC files through a Schiit DAC with Morrow MA5 interconnects . I wish I could find someone in central California with a Sachs pre to compare side by side. I'm not impressed with the Rogues headphone section and I haven't gone back to vinyl YET . But  as far as I've gone I'm happy. By the time you get the Rogue , tubes and a power cord you're at $2000, so take that into consideration . Based on what I've read online, Donn Sachs will be my next Pre . I'm also curios about Balanced in and out . I'd go deluxe on the upgrades , so it would still be more than the Rogue . I play the snot outta my system and 18 months in no issues . When I get the Sachs I'm gonna go 100 wpc + tubes or 200 wpc + SS. As I have low power now . I'm interested to hear how this plays out . I'll probably benefit from this thread as much as you . I like the gentleman's opinion about his tube compliment as that answered one of my questions . I tried some Psvane TI power tubes and found the bass light too . I prefer Gold Lion reissue and SED Winged C over them . In the Rogue I've tried Telefunken , Seimens Nickel plates, RCA JAN blackplates, NOS Mullard . They all bettered the provided JJ's. So I wish you the best . Thanks to all and Happy Listening, Mike. 

@jmac7,
I guess, like Kevin Deal of Prima Luna /Upsacale audio claims in his Utube video's the Primaluna Pre-amps weigh more than other Pre-amps, made by other manufacturer's well ! having heard Don Sachs amp the choice was between Weight & Sound quality so I choice sound quality He He He !
at the same price point  not to say that prema Luna's are not good pre-amps, I have also heard good things about Rogue Audio RP-1 but have already ordered DS 2 in a Walnut case with upgraded caps , meanwhile I do have a VTA-SP-14(tubes4HIfi.com/SP14) on loan from @whitestix that I am listening to in my system

I have also ordered Don Sachs Model 2 in Walnut and extra goodies; many praise this unit as a true reference sounding pre-amp and I'm looking forward on implementing in my system.

I can't comment on Don Sach's custom, but I built the VTA kit that is the starting point for his.
I couldn't be happier, & his can only be better!
