What tube pre-amps pair well with Pass amps?
Pass Labs whether due to technological or marketing reasons promotes their “super symmetry” as a selling point. This might be best used in balanced mode. Some of the Pass Labs amps have a somewhat low input impedance.  If wanting to use tubes, I s... 
What tube pre-amps pair well with Pass amps?
@billtro Ama-sphere (unsurprisingly) makes preamps that conform. I presume that Pass does as well. Unsure unfortunately about other brands, perhaps some others will know of some options... 
What makes a DAC so expensive?
And in my experience, when a designer uses high quality parts like these, that means they’ve got a product where they really care about the sound and have carefully manicured it’s performance. I bought my audio Mirror dac because of this reason an... 
What makes a DAC so expensive?
I was going to get on and say exactly what Bill did.. @grannyring .  Here's a link to the dac I suspect he was talking about. https://cdn11.bigcommerce.com/s-210bb/images/stencil/2048x2048/products/156/1340/Mystique_EVO_Inside...Good luck getting ... 
D'agostino amplifiers: where's the beef?
While I don't disagree with anything you're saying, I also know that yg acoustics uses D’Agostino amplifiers in their in-factory listening room. Given that they could afford to have anything in there, I do believe those amplifiers can be a preferr... 
Preamp suggestions, yes again
Congrats! Hope you love it. 
Seems tough to ensure only subwoofer is playing bass frequencies (& not the main speakers)
I also run my speakers full range (down to 20hz) and reinforce the bottom end with an audio Kenesis swarm inspired subwoofer setup (two additional subs). The subs play from 16-80ish hz and integrate really well. If you can echolocate them, somethi...

@scothurwitz Thanks for posting that. My mistake actually just occurred to me yesterday and I was going to hop on to correct the error. Always great to make a mistake like that while correcting someone else's. Much appreciated. And apologies to Ke... 
Preamp suggestions, yes again
Hi @donsachs  Very sorry for implying that your build is the same as the sp14 kit. Was definitely not my intention!  I've not heard the sp14, but definitely do believe that your version sounds better... which is why I own and love one (despite doi...

Maybe after an upgrade posters will start actually trying to help one another learn rather than engaging the routine dominance/elitism battles that break out in every thread. Sigh... 
Audio GD XA150 Monoblocks
Agreed that if you care about heat production and electrical consumption, then class a is not for you. That's going to knock a lot of very successful and high performing amps out of consideration though. In my mind these amps should really be comp...
