Bass management with stand alone preamps

In researching an upgrade to separate preamp from an av pre pro (marantz 8802a) I’ve noticed that 1) most include no bass management 2) some include dual preouts but no bass management 3) some have a basic sub preout but no bass management.    Are subs not popular in the two channel arena?  I know in years past they were considered anathema but like every other issue in society views seem to have changed.  Interested in how people typically integrate and if NOT running the mains with a high pass filter is common.  Seems part of the point is to take that out of the amp and speaker and direct all that effort to the sub. If this has been beaten to death in another thread feel free to redirect. I have JL F212V2 subs which don’t have high level connections like REL appears to have.

 Thanks for the replies. For clarity the marantz is a prepro ( I have all my equipment listed in the virtual systems) and from reviews I’ve read holds its own as a two channel preamp but I have been interested in how bug a jump it would be from my current setup to say a levinson 585 integrated  and then from that to a separate levinson pre and amp combo.  The integrated is significantly cheaper, on audiogon probably 1/3 to 1/4 the cost of a comparable pre/ amp combo not factoring in an extra power cable or two and more interconnects.  If one should room isn’t perfect/ treated is this all a waste of $ until ?

Audiophile preamps with full bass management are relatively rare. Some have been mentioned by others. A few more are

  • Anthem STR Preamp (also STR Integrated)
  • miniDSP SHD
  • Classe Delta Pre, not yet released. (Its predecessor, the Classe CP-800, has bass management for 1 or 2 subs.)
  • Trinnov Amethyst (warning: has a fan)
  • Legacy Wavelet
  • NAD C658D (though the bass management firmware may not have been released yet)
As noted, many audiophiles (not me) think that DSP, bass management, or any type of tone controls limit the sound quality. In my opinion, the newest DSP products are quite good, and in many practical situations, the benefits far outweigh any drawbacks.

mike, the Trinnovs fan is dead silent. Very slow speed. It does tell you how much computing power they have in there. A Lot. To call it a preamp is an understatement. It is the best room control available at this point, it is digital bass management for two channels although not quite as powerful as the TACT bass management and it is a DAC. It is also $11,000 with microphone.

Is this Trinnovs first foray into two channel?  I hold them mostly as a home theater type company.
