Bass audition for your system....

gosta, the Saint Saenz I have is the Telarc I indicated.

@twoleftears 
I love the Mussorgsky Pictures at an Exhibition but do not own it. Is that recording in the link still the go to recording?

I'll look up the Saint-Saenz symphony when I get home but I think it is the Eugene Ormandy, Philadelphia Orchestra on Telarc or London.

It is undoubtedly the Ormandy/Philadelphia recording on Telarc. It is a great recording with an unbelievable climax. Seek and ye shall be rewarded. 

As @Jafant mentions Jamie Cullum is a young talented man that really gets the SQ right. "Photograph" on his cd Cathing Tales is another track (of many) where the fine bass (electric in this case) has to fight a little to be heard (after the intro). Please, do not miss "When I get famous" on the cd "Momentum". What a groove. Makes you feel good all day.

Unfortunately Telarc is not yet on Tidal. Going through all other recordings of the organ and the pictures. Like these old Living Stereo recordings. A problem with classical symphonic recordings to me is that most of them tend to have 40% of the orchestra in the left respectively the right speaker and only 20% in the middle. Seems unnatural. Makes you sit too close. They are also rather different in tempo and "effects". And SQ. Will report back.

@n80 Pictures at an Exhibition was originally composed for piano.  It was subsequently orchestrated for full orchestra.  The link is to an organ adaptation--I presume based mainly on the piano original.  There are notes there that will make your bellbottoms flap in the breeze.
