Vinyl playback - lack of bass?

Digital is supposed to be able to handle more bass than vinyl, but I’m pretty sure in reality that capability is not utilized very often. I have a few records where I have both analog and digital copies and I really don’t hear any difference in bass response between any of them.

I agree that bass response in older records can be very lacking. That seemed to start to improve in the early seventies but didn’t seem to become consistent until the eighties.

Also a lot of rooms will accentuate the mid range, so some room treatments and or room correction can help balance out the sound.

Recordings:

Analog versions differ vs Digital versions differ

= apples and oranges 

There are a lot of variables.  The mastering of every recording is different.  Many, if not most recordings, and especially digital streams are compressed.  Phono cartridges are not perfectly linear.  There are extra stages of amplification in the analogue signal path.  Then there is the RIAA equalization curve that is never perfect.  So, things will sound different.

If anything, I always thought that Rega's design philosophy, ultra light weight minimalist construction with emphasis on rigidity and structural strength, might possibly result in a slightly reticent bass response. No matter what is the cause, even if it is nothing but audiophilia, it would be difficult to ferret out. I do not agree that the difference is purely the difference between analog and digital.  The best analog bass response can be superior to digital in terms of tonal richness, differentiation of instruments, and sense of depth.

Components make the difference... when the same source material is used (same mastered recordings).

It is your turntable/ cartridge / phonostage. I used to own Olympica 3 speakers and a Pass 350 amp with Simm DAC and CD player. My turntable sounded better than streaming or CDs. With more bass. Simm is detailed oriented and lean sounding. I highly recommend a high quality tube phono stage and turntable. 

My current system the analog and digital legs sound the same... by design. 

I highly recommend being very careful when using subs, They are really easy to turn up too loud or cross over to high and end up negatively impacting the overall sound. It can confuse the central image, disrupt the sound stage. I have frequently walked into a system with a subwoofer(s)... and instantly go over and turn them down... to the delight of the owner.
