Several of you are claiming that digital volume controls are inferior to non-digital controls. Two or three days ago, I watched a video by Paul McGowan of PS Audio saying just the opposite. Yes, in the early days of digital, at lower volumes, the digital controls sacrificed word length at lower volumes, as they were controlled by one, or in a few cases, two 16 bit chips. But, according to Paul, todays controls are extremely linear. He also explained how even the best non-linear controls increase noise levels at lower volumes, and can not compete with today's digital controls. He further explains that that is why very few designers today use anything but digital controls. You can believe what you want, I'm just throwing in what one industry biggie thinks on the subject as food for thought.
What will a preamp do for me?
Missing in the chain below is a preamp - I use the DAC to control volume. This is my only source and will be for some time. What could I gain by adding a preamp?
I have Thiel CS 2.3s driven by a BAT VK-55, sourced by PS Audio PW DAC, with bridge II, mostly tidal. The DAC serves as a preamp in terms of volume control. Mostly Audioquest cables, amp power cord is Cardas Clear m, all fed by PS Audio upc-200.
I am am hoping to improve the highs, which sometimes sound smeared, too much sibilance; would like more air and clarity. Loud rock sounds flatter, less dynamic than I’d like. I am not willing to give up the deep detailed and beautifully resonant mids. Willing to spend up to $3000, used is ok. Totally balanced is a must. Not currently willing to entertain the idea of different speakers - my goal is to make the 2.3s sound as good as reasonably possible before moving on to other speakers. It’s easy to find a really good preamp in this price range, so much so I am almost paralyzed by the choices. Aesthetix , Ayre, ARC, several BAT, Parasound and more all have apparently excellent models in my price range. Patience would put Atma-sphere and PS Audio within reach. Which is best for my situation? There’s no way to audition all of these, how could I avoid getting on a preamp merry-go-round? Or should I spend my money elsewhere?
