Where s the bass?

My system - Sony CD player, Pass Labs X0 preamp & X600 amps, Thiel 7.2 and Transparent Reference cables. I believe the sound is open, transparent, and dynamics. However I just wish I could put an emphasis on the bottom end. Tone controls are not available on high quality Class A preamps, such as the X0. While I understand that adding one more component in the signal paths is not desirable as it will further degrade the sound, I would like to hear your opinions on the best way to boost the bottom end. Thank you.

Try putting your listening chair against the back wall. This will elevate the bass level, all other things being equal.

I think perhaps the high output impedence of the BAT is providing an upper bass lift. Placement in the room and so on is reinforcing this. The Pass is essentially insensitive, thus giving an even FR - no lift. If there is a suckout at the bass frequencies at this placement spot, the "tone control" of the BAT "evens out" the FR, making the Pass seem anemic. Sort of a Fletcher-Munson effect. I bet turning up the volume makes the Pass bass more attractive?
