Have the Golden Ear Tech 7's but considering a speaker a fuller sound and also musical


As mentioned I have a pair of Golden Ear Technology model 7's  much raved about at CES 2012.  It is a good sounding speaker but after 18 months of ownership, I have noticed there is a fullness missing in the midrange. The system  has remained basically the same in the system over last 18 months, except fort the Blue Circle Thingee power line conditioner. They are powered by a Rogue Sphinx  v.1 integrated amp (100RMS), and sources material is Ayre CX-7e mp CD player and a refurbished   Thorens  TD145 which may be on its way out the door  soon .  

Speaker cable is shared by Grover Huffman EX cable, and Harmonic Technology older  Pro 11 + speaker cable. The IC to CD is Harmonic Tech "TruthLink " 

I am considering  the following speakers:    Magneplanar .7 or 1.7;   Vandersteen 2CE;   Scansonic 2.5    I am open to suggestions up to $3000   Would prefer a sound signature that is transparent, musical and easy to listen to.   Thank you.

Thank you to those who have responded  so far  JR from Audioconnection, thank you for the offer, but I would prefer  not to be solicit by audio dealer about their products product.  Also, I really don't need to be coached because I have been involved in audio since 1971.   Thank you  .
I would imagine the amp uses cheap Chinese tubes.A simple tube upgrade may go a long way towards adding richness to the tone...
To, Freediver,  I am ahead of you brother on this suggestion which I appreciate.  I changed out the TWO standard tubes of the Rogue Sphinx output stage with two Mullard 4003V tubes about 1 year ago. A member recommended the  replacements to take the edge off of the Hypex Class D chip that Rogue uses. It did remove about 80 %  of the edge and brightness, but some still remains, but is not unbearable. The GET model 7 speaker has many virtues of soundstage, clarity, and general coherence, but  sounds moderately bright  with even the best of the class D did amps. or just standard SS amps. So the combo can be a problem.
Never heard the Tritons but did spend time demoing the new Martin Logan Motion series & found the Heil type tweeter bordering on bright.I agree with your assessment that between the Class D amp & GE speakers your just too far into the upper freqs.to achieve a good balance.
 Hows the room?Maybe a bit of acoustic treatment can tone it down...
