I was in a similar situation last year, running the PS Audio Directstream DAC directly into my power amp. It sounded good but not as good as I wished it did. So I swallowed hard and bought their BHK signature preamp. Sound is much improved, in just the ways you seem to be looking for. I was able to get one for significantly less than list price from Upscale Audio -- pretty close to the price for a used one and to the top of your budget range. You might give them a call and see what they are willing to do. (On the other hand I am not in a position to say that this current model sounds drastically better than the used one you can get for a tenth the price. Haven't heard the 4.6. Or the Schiit)
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?
