Sound without the Preamp ?


I thought I posted this before, but can't find it so here goes. I need some help here. I removed my tubed preamp and plugged the balanced interconnects directly from the 2 tube monoblocks directly to an Accuphase CD player with volume control. A weird thing happened. The sound got better, more transparent, deeper and tighter base. I find this indded strange because, this tube preamp is one of the industry's heavyweights, with a price to prove it too. Am I just "hearing things " ??

When I bought my first CD player with a volume control (CAL CL-15) I decided to try it feeding directly into my CJ amp. That was two years ago and I still don't use a pre-amp. It works for me and judging from the previous comments, I'm not alone.
I have a solid state system: Older Proceed DAP connected directly into an Adcom 5802. When I used the Adcom GFP 750 preamp I noticed loss of dynamics and clarity. My DAP has a "hybrid" digital/analog volume control. I have read that controlling the volume in the analog stage is the best for resolution preservation, esp. at low volumes. Any opinions on this?
I too have had great results getting rid of the preamp. I recently upgraded from Meridian 506.24 with Adcom GFP 750 to the Wadia 860x player. I compared the Wadia with and without the preamp, and it was WAY better without. I'm going to spend the extra money saved on better interconnect.
I have found that replacing the active preamp with a passive / direct does increase the "hi-fi" sounds (imaging,soundstage,noise, etc) but detracts from the "musical" aspects of the performance (dynamics,timbre,pace,rythym,etc.) anyone agree?? I ask why so many listen to an active linestage when a passive is so much less expensive / less complicated??
Passive preamps have nothing to do with a CD player that has an integrated volume control, as I've said many times before. Such a CD player simply and effectively puts an active linestage inside the chassis of the CD player...just in case some are misunderstanding that.
