Krell K300p Phono Stage


One of the hooks that grabbed me when I first fell for high end audio was that it totally aligned with my need to obsess over whatever brand of gizmo or gadget that caught my eye. After all, my entire childhood was defined by a series of brands I'd obsess about from the likes of... Read More »

The Simaudio Moon 810LP Phono Preamplifier - A Flagship Offering that Checks all the Boxes and More


As I continue to re-evaluate my system, I have been auditioning various standalone tube phono preamplifiers. I am a big fan of utilizing tubes in the front end of my system when paired with solid-state preamplifiers and/or amplifiers. The unwritten rule claimed by many audiophiles is that there must be tubes somewhere in the system... Read More »


Affordable Magic - the SOTA Pyxi Phono Stage


Recently, I was reading about a leading industry engineer who strived for components that were "one-noters."

So why all the Etc's? Because, while nominally an affordable MM/MC phono stage, the Parks Audio Puffin incorporates a flock of features and functions simply unavailable in phono stages commanding ten times the asking price ($489 to $639 depending on options). OK, not at any price. But for starters, the Puffin does do the phono... Read More »
