Help. A box beats my Maggie

Got a Magneplanar 1.6QR over a year ago and it immediately blew my Cabasse Farella away. Was using a NAD C370 then with Marantz CD17m2ki. Without a second thought, I immediately place the Farella at the local dealer for resale. Later on, replaced the C370 with a Plinius 8200mk1 and it gave a great improvement in performance from the Maggie except it is a tad underpowered sometimes in my big room. C370 has more power.

Last week, frustrated that the dealer cannot sell off my Farella, I decided to take it back and hook it up to my Plinius 8200mk1 and in a nutshell, my jaws dropped. Literally! If there is a match made in heaven, this is it. The Farella is LIGHTNING fast, with FRIGHTENING dynamic. The soundstage is as wide as my Maggie and things just opened up more. More details. It retains the nice tone of the Plinius to boots. After having the Maggie, I am hooked on it’s box-less sound. Guess what, the Farella has very little box coloration and I can listen to them for hours. For the record, I cannot stand the majority of box speaker because of coloration. I like the Plinius+Farella so much that I have temporary put my Maggie aside and here comes my reason for writing all these.

I believe the 1.6QR are capable of much more then what I am able to get out of it with the Plinius. I would like to know what amplifiers are there that will improves on the Plinius without breaking the bank (I may be willing to spend 2x more). I realize some people will go for power at the expense of quality. I am not prepared to do that. Getting a Plinius SA10* power amp seems to be the logical move but unfortunately, I cannot audition them here. I would like to know whether the SA10* can give me almost twice the performance of the 8200mk1 because if it doesn’t, then I am afraid I will prefer to play with the Farella instead of the Maggie for the time being. IMHO, this is simply a case of a more perfect synergy matching of Farella then the Maggie. Nothing more.

I read there is a fellow going by the moniker Cpdunn99 who mentioned a marriage made in heaven of his Cabasse speaker and Plinius 8200. If you are reading this, I would love to hear your cabling/cord selection. Presently, I find that most things with silver seem to be a poor match and copper seems to be the way to go.
