I used a Carver PM 1.5 for my CLSZ2 for years with good result. I substituted a Sunfire Signature which I did not like and ultimately replaced it with a Bryston. The Carver had a really balanced presentation not unlike the Bryston. The Sunfire was just too syrupy for me on either output choice...
As long as the pair of panels is good/ working well… I have a great friend that also had a pair of CLSZ2 like mine … he will help me with the install next time he’s in Florida. Please pursue the costs to ship. Thank you.
The Request is still one of their best. I have heard and like the newer Logans but there is something about taking the crossover frequency lower/ down further to the panels that provides a better experience in the room.
Have listened to both on several occasions...Request has a better panel to the extent it covers more range as the crossover point is lower but the woofer IMO is behind the SL3 in bass quality and melding with the panel.
