High sensitivity speakers have had a following amongst the proponents of low power single ended tube amplifiers for a long time. Many of these speakers work well with these low power amps, but not necessarily with more typical amplification. Not so with these Zu audio Druids. While I am sure they still are wonderful with low power tube amps, they also deliver with more typical solid-state amplification. The Druid, made by cable and speaker manufacturer Zu Audio in Ogden, Utah, has had a cult following among many audiophiles. I was able to test the latest Mk. 4/08 version, released earlier this year.
As I said at the beginning of this review, now is a good time to be an audiophile. The Parasound 2100 preamplifier and 2250 power amplifier offer sound quality across the board so good I would have thought you'd have to pay at least $3,000 to get them. But, at a mere $1800, the Parasounds are a steal.
Wireworld's Eclipse 52 cable line is an example of definitive electrical engineering and physics principles applied to conduction in the world of audio. Specifically, their cables are based on the Heaviside condition. Read on to see an explanation.
Impedance is the extension of the idea of electrical resistance to AC signals (like music). In high school, we all likely learned Ohm's law at some time or another. Whether we remember it or not is another story! Luckily, the refresher course is easy. Resistance is a way of relating voltage and current in a simple DC circuit.
Oppo Digital is a very rare light among the stifling mediocrity found in most low to middle priced digital audio and video electronics. Readers of this website know that we all have a virtually uniform love for their products, and it is for extremely good reason.
