We have similar components. I had PS GCP 200/GCPS and sold it after listening to the XLR variable outs of my 168. I also had GCA 250 with Underwood Level 2 mod. I used it to drive my Magnepan 2.5R bass panels and another amp for the ribbons.
I am now using a Wyred 4 Sound MC 250/500.
I use an active XO.
I found speaker cables and interconnects made a BIG difference. I now use Clear Day solid core double shotgun silver and a mix of PS Audio Transcendent Silver XLR and DH Labs Revelation. Power Cords- Tek Line Cables new Reference series- both the micro and the micro Ref Extreme.
You might try the cable route first, as you will need them no matter what speakers you send up with. Maggies are unbelievable if you have the room. The reference 3A Veena is an outstanding monkey coffin. Personally I am addicted to ribbons/planars.
