Hi all,
Those of you using a pre with your Decware amp will be able to relate to this...
I retired my CSP2+ last Spring when I got my Zen Select, which of course has built in volume control. I recently decided to sell the CSP2+ rather than let it sit and collect dust, and while I had it out to snap some pics, hooked it up to the Zen just for fun. Holy smokes! I can't believe how much the CSP2+ transformed the sound of the Zen for the better. Everything has improved--sound-stage is wider, imaging more focused, and most surprising (and welcome), the bass is tighter and goes much deeper than before, making the music punchier and more dynamic. The music is also a lot more holographic now with the CSP2+ in the chain. I thought the Zen alone had great pin-point imaging, but now I know what people mean when they say it's like the musicians are in the room with with them. I finally feel like the system is using my speakers to their full potential.
I can't believe I had this major upgrade just rotting away in my closet for the past 10 months! I'm still using the stepped attenuator on the Zen Select as main volume control, with the CSP2+'s input and output pots wide open, and stepped attenuator set at 12 clicks.
