New PH 9.0XT Review in The Ear, by Jason Kennedy. So excited about this review and grateful for yet another rave from the UK and Award!

ModBlog – History of Digital Audio: Have we made progress? “You Spin me right round bayby, like a record baby, right round right round”, Dead or Alive (1985) Born in 1970, I have experienced LP’s, 8-track, Cassettes, CD’s, streaming and now at age 55 I listen to LP’s. Digital Audio was born in my lifetime…

Solid state amplifiers, all use BJT or Mosfet power transistors at their outputs, including Class D designs. The purpose of the transistor in this case is to buffer current into low impedance speaker loads. So, which transistor should we use and how do they differ in sound? The two basic choices are Mosfets (Metal-Oxide Semiconductor…

Class A vs. Class AB: What Bias, Heat, Distortion & Design Really Mean for the Music You Hear When we refer to amplifier “Class”, we are really talking about how the amplifier’s output stage is biased. Class A and Class AB are different amplifier classes with unique properties, strengths and sonic signature. Amplifier “Class” andbias…

When you sit down to listen to your system, are you anlyzing or enjoying? As audiophiles, we all start off in search of better sound. We had an initial experience that imprinted upon us. We heard music sound better than we thought possible. This led us down the rabbit hole, into the audiophile world. We…

Maybe I am just getting old-er, but who isn’t? I find myself leaning into things that make me smile. I am tired of chasing perfect digital sound, new technology, jitter reduction, etc. I do listen to digital and it is great. However, I find myself just grabbing a record these days, when I want to…

We have designed tube and solid state amplifiers over the years. I have explored conventional approaches in both tube and solid state design. In all amplifier designs, I found that the simplest and most elegant solution is best. By challenging conventions, we have found or own solutions. Excluding global negative feedback allows us to streamline…

In the last post, I discussed the important elements of a good preamp and what I feel is important, as well as the design elements that I consider key to good sound and performance. Enter the LS 300, our Reference Balanced tube preamplifier. As stated previously, I prefer a preamp to have lean functions and…

I prefer to design tube preamplifiers and solid-state amplifiers. The reason for this is simple. Tubes amplify voltage. Transistors amplify current. So, what is the purpose of a preamp? In modern terms, it is a simpler function than it used to be. Today’s sources have adequate gain to drive most amplifiers to full volume. Audiophiles…
