REVIEW: Secret's Vault wrote: "It isn’t hard to tell that the sun is bright, and it’s equally obvious that the PS-1 is a special product. My previous phono stages ... were the Audio Alchemy VAC-in-the-box and the DB Audio PS-8. These are good, listenable and musical phono stages ... but man, did the Monolithic PS-1 ever eat them for lunch! Yummy. Note that the PS-1 retails for just $399 – that’s pretty much dirt cheap for true, no-concessions build and sound quality. Sure, you need the HC-1 to bring out its best, and that moves it closer in price to the “competition” mentioned above, but in stock format with the regular power supply, it still walks on the other budget phono stages."
