Which one would you buy

But this is also a good opportunity to work in my regular "Alps Blue Velvet" pot bashing, which Sky-Fi advertises as using in their unit.

100% agreed, though honestly there are worse offenders out there than this little $855 amp.

To wit, from the product page of a $5,995 preamp:

Look inside the most well-known brand of tube preamps and you will see a chip called a DS1666-10 Digital Resistor IC. At Primaluna, we understand the temptation to use this chip as they cost $4 each (half that in quantity!). The preamp will sound fine and be quiet, but true to “chips” it will add an electronic “sheen” to the sound. PrimaLuna prefers analogue. And we use the Gold Standard in motorized potentiometers:  The iconic Alps Blue Velvet. Why? Because they track perfectly, stay quiet, and don’t sound like chips!

@devinplombier We all hate the Alps BV! I replaced the volume pot on my tube preamplifier.

Sky-fi has been driving up prices for years on equipment that does not come close to what it’s worth. I honestly think they are money laundering, can’t come to any other reason for some of their pricing. I would never buy from them. The other seems a like a reasonable priced unit and looks to be in good shape.  

Sky-Fi is dead to me.  I questioned them once on their “made up” retail price and was immediately blocked.  No warning, just blocked.  I have secretly hoped they would go out of business in the last 10 years.  My prayers have not been answered yet.  

Why have you narrowed it down to these two.
