It's bright and early on Saturday morning and I'm up drinking espresso, as my custom is lately, starting my mornings with two café allongés to get the morning rolling. It works! My primary music system has achieved such a nice overall balance musically & sonically of late that I'm just sitting back, settling in, and enjoying the fruits of... Read More »

Yazaki-san’s superb SPEC RSA-M3 EX Real Sound Amplifier is a perfect match to my Stokowski A7's, giving a musical... Read More »
