If you're a baby boomer (OK, Boomer!) or one of their children, you no doubt have a strong familiarity of the works of jazz pianist Vince Guaraldi.

If you believe in RFI—no, let me start over. If you believe in science (since RFI is a measurable phenomenon), most likely you are doing something to address RFI.

A fairly common thread that runs through most audiophiles who are partial to vinyl rather than digital, is their penchant for tweaking.

He was a wickedly gifted guitar player, and his band had often gone head to head against another local band, Mr.... Read More »

Auditioning cartridges is a lot like wine tasting and shopping for televisions. You never know how good a glass of wine from a $100 bottle tastes compared to a $10 bottle until you've experience it for yourself.

To them, I love relating details of a historical sporting event where footers, or in this instance, shoes, made all the difference to the... Read More »

I think most of us are aware of E.A.T. and their turntables and cartridges. You may have read Robert Levi's review on the stunning Jo No. 5 cartridge back in our July 2018 issue (HERE).

I recently reviewed the entry level Boulder 508 phono stage, and it surprised the boots off me by its price / performance ratio. It's so good, in fact, that it ended up finding a permanent spot in my system. Since then I have been following the roll out of Boulder's latest product, the 866 integrated... Read More »
