Thrax Maximinus D/A Converter + Dionysos Preamplifier + Spartacus Power Amplifier


Rumen Artarski is a hunk of a man. Tall, handsome and ramrod-straight. He could serve in Special Forces or join the Honor Guard. He could be a grenadier or serve in the praetorian guard of the Caesars. There is some inner strength in Rumen—he is big, but not bulky or sluggish. When he first wrote... Read More »


Red Dragon Audio M500 and M1000 MkII Amplifiers


Here We Go Again Over many years I've endured hope and disappointment in the service of auditioning and evaluating loud speakers of virtually every sort.

The Audio Circular - No. 9 in a Series of Parallel Narratives Boosting the Flea: The Unison Research Unico Upower Amplifier

Planning for a move from my current country mouse lifestyle in up-state New York, (i.e. old large Victorian high ceiling dedicated listening room), to the ultimate city mouse experience, (small Manhattan apartment with multi-purpose rooms), created a logistical and musical challenge that I...

The Audio Circular: No. 10 in a Series of Parallel Narratives: Push-Pull Thermo Muscle: The Rogue Audio M-180 Monoblock Amplifiers!


For several years I've been living in the land of low watt tube SET amplifiers: 2A3, 45, 300B and 845 Triode amps have been in my personal collection. Lately, the arrival of a new pair of reference speakers finds me auditioning higher power amps. There is quite a difference between a gaggle of glass bottles... Read More »


An Audio Feast: Magnepan, Pass Labs, Oppo Digital, and Cardas!


Background You always remember your first love. In my case, at least audio-wise, that was with a pair of Magnepan 3.3's. I was struck by the way the sound filled the listening room—it sounded like the entire wall was radiating sound. Not just any sound, but crystal-clear sound. I still remember the way the highs...
