Amp for Harbeth P3ESR


I am looking for an amp synergy with Harbeths.

With one qualification. I was looking for an amp with a high-pass filter of some kind with use of a sub-woofer as to open the mid-range of the harbeth's a little and to extend the bass and improve impact.
Most of the amps suggested for the Harbeth sound are very minimalistic. (certainly the lfd which is my number one choice). How could I use a subwoofer in such a setup as described to open the midrange?

The one option I have found is the Naim Uniti but alas it is out of my price range and they hardly ever come up used on here.

Owned the Naim XS-2; w/ Flatcap XS and drove the P3ESR SE's happily. An amazing combination.

Detailed but not analytical; and surprisingly able to reach good low frequency reproduction without embarrassing itself. Plenty of PRAT as detailed above.

Purchased the LFD LE Mk IV- and sold the Naim the very next day. It's that good. Again, I was very happy and could easily have lived with the Naim combo; but enjoyed the LFD a touch better.
Ive considered the LFD but cant listen to it in my city. Same goes for the Luxman 505u. I have heard the Ayre ax7e and it mates very well with my c7es3's. Might do an in home demo in October. Currently running. Rogue Cronus Magnum which I will be keeping.
These are great speakers,but they are limited in dynamic response. Also for the comment about adding a subwoofer to these will not affect the midrange is incorrect. Any loudspeaker that is operated through a high pass filter will have a different midrange response. Since the Harbeths are a small two way, this is definitely true. Whether this change is better or worse is the opinion of whoever is listening.

Going back to the P3ESRs and this time around, got me a LFD IV. LFD is on the way. Any DSD DAC recomendations for this combo? Already have a CAPs server with a firewire card so I'm tempted to get another Mytek 192. Other thought was just to do vinyl for and wait for RMAF 2014.

Other thing I'm wondering is if an LFD phono would be better then my Phonomena II on a pro-ject 5.1.
Not a fan of the Phonomena so I'm guessing the LFD is better... but you should really invest in a high quality phono preamp as soon as you budget allows. It could make a huge difference with the P3s because they are capable of such sweet sound.
