A lot of hype about PS Audio, deservedly so ?

Yes, it was their Dac that caught my eye too, I like the way that it is software upgradable.
Have not had separates before, I like to have a simple system as possible, therefore have been looking more into Luxman and Accuphase integrated amps, that are well made and get good reviews, must say I like that looks of them too ;-) also my speakers don’t need that much of power, how do you guys like the headphone output on the pre amp ? 

I can echo the posts above regarding PS Audio. I own, and love, their P10. (bass not flabby in the slightest, btw) I own, and absolutely love, their Stellar M700 monoblocks which I use as front and center channel for my HT with a Stellar S300 for the rears. I replaced my McIntosh MC205 and haven't looked back. I own, and love to an absurd degree, their Directstream DAC. Red Cloud firmware has finally brought digital to the level of musicality of my excellent vinyl rig, which I never thought would happen. Their service is top notch. Their enthusiasm for their products is genuine. Their product line is ever expanding with an upcoming server/streamer and BHK phono preamp (and Stellar phono pre). So yeah, I'm a big fan of a well run American company which manufactures here. Not much hype to that. 

Paul McG wrote in a thread at PS Audio.com concerning this thread:

”Thanks, guys. Yes, with the exception of Sprout and the Dectet, everything we build we build here and source most of the parts here as well. We use vendors from Kansas to California for circuit boards, though most of the metal work is done in Colorado. We’ve got 38 wonderful people working hard to make these products for you right here in the good old USA.
I would encourage anyone in the area to come by and visit. While I know most companies in our business might be a little standoffish of unannounced visitors, you’ll find us quite the opposite. Come on by and watch your products being made and see where they are designed and listened to”

To the OP:
The answers to yours questions are:
Yes, Yes, and Yes.
I am very fortunate that an audio company PS Audio exists and right in my back yard.
Paul sends out a daily dialogue to patrons every day, which CEO does that on this planet. 

I stumbled upon Paul McGowan's YouTube Vids which caused me to re-invest (?) myself in my already wonderful music system. Replacing my Audio Research Transport was no easy parting, but the PS Audio transport took everything to a new level. I am awaiting delivery of my new ( used ) PS DAC on Monday to experience the magic of I2S connects between the two, the streaming benefits, and to continue the adventure into musical "nirvana" .  Re-discovery on my music library awaits .   I see PS mono blocks in my future also .
PS  = Perfect Sound , Professional Service, Passionate Staff, Prominent Style , Powerful System !    No Hype ... IMO
