Building my 'first' system - Advice on Phono preamp please

Nice streamer. You running Volumio? It really improves with increased DAC quality.   
Look at Parks Puffin. It does more tricks than a trained monkey.

Your first proper system is a key statement. Don’t start out too exotic or your mis-match may end up costing you dearly. In the beginning it may behoove your interest by sticking to the basic’s and eventually add a little flair. The manufacturer has most likely done most of the compatibility research for you. Add a good set of speakers and it’s off to the races. Usually the manufacture will recommend what impedance to look for when selecting speakers in order to achieve maximum performance for their particular system. Many of the newer units have built in DACS and offer a wide variety of I/O’s for expansion. There’s nothing worse than finding out a few weeks down the road that your system can’t support the add-on. Quite honestly it’s your listening pleasure that should be driving what to look for in a system. It’s only my opinion but I found over time that tube systems offer more resonance and warmth for an instrumental genre while solid state systems have more defined edges that enhances hard rock music.

If I lived near the Space-Tech Labs store, I would go there and audition their stuff and buy from them if you find it a good value. Always loved checking out their stuff, but I'm half way across the country and unable to audition their stuff.

Two similar but somewhat different approaches. Right now you and everyone else is on the approach of the common wisdom (aka stuck in a rut, running a treadmill, etc) approach of finding a phono stage that is about as good in price or performance as the rest of your system. Perfectly natural if misplaced assumption approach.  

This approach only works if you are contemplating a static system, one where seldom if ever will anything be upgraded. One and done, run it till it don't run no more. In that case follow their advice. Might as well. Won't matter much either way.

The other approach is if you plan on gradually over time upgrading one thing after another. It can be very slow and gradual so it takes years to do the whole system. Still this merits a considerably different approach.  

In the first you can buy any of the mid level things recommended above. In the second you might want to stretch a bit for something quite a bit above average. Phono stages, turntables, analog in general is a completely different animal than digital. A good phono stage can last you many many years. It did me. The ARC PH3SE lasted me 16 years through multiple CDP, amps, even turntables, arms and cartridges. When new it cost more than my speakers. For years it was the most expensive component in my system. But that whole system grew up around it, so by the time it was replaced with a Herron it was a completely different system.

Little bit more strategic planning than you were expecting, I bet. But there it is.
