Are there any DACs that can go low?

I agree with the suggestion that you pay attention to the output stage of your DACs. Best output stage I have heard on a DAC was from the analog maestros at Yamamoto, on their YDA-01 DAC

Lets not forget that an analog turntable can produce some subsonic info that a digital source of the same recording will not. Sometimes added subsonics can influence the bass perception heard by the listener.

Further, I believe a analog produced sound image will be different than a digital reproduction of the same source in part due to the reduced channel separation of a phono cartridge. The best channel separation in a cartridge will be many dB lower than a digital source. Notice I say different, not better or worse.

Dsd audio as well as any quality dac now can go toe to toe with Any turntables for or less money.
Dollar per dollar,digital has better s/n ratio, dynamic range, lower noise floor, and for sure lower Bass. But people have using turntables for so long
Including myself is because it sounds so natural.the tide now has turned.
I use DB power amp to rip cds to a External SS drive,then To J Rivers to a Auraliti Player 1500 Album library.Mytek makes a nice dac for !$1500 range to step it up to the Aurender Vega dac,for $4500 retail including the player and I Pad, it will smoke Any $15k turntable setup even more
iMO, and no crackly disks to clean. I just use my I Pad to pull up Wav files,
Hirez, or DSD downloads And just relax.the hardest part is ripping
Cds to the HD. When I read articles on turntables for $100K ,I Say for what
Just more work to do? Some people just want to re live the past,which
Is fine ,just not for me .

If you are after great bass and analog SQ (no harshness) from CD rips, this is the DAC:

No-risk either. 30-day money-back.

Any decent DAC can 'read' the signal which contains all the info necessary. The bass is there but it can be something as simple as impedance matching or it can be the quality of the power supply to the DAC.

I've had several CDPs and thought they were all quite fine until I got a SACD player (Marantz SA15S2b) with a well built (over built?) power supply and the bass I got out of my system floored me. And that was with Redbook. The DAC in it is no different than what's used in some of the stand alone DACs out there. It's all a matter of how it's implemented.

All the best,
