Time for a Pre change? Need the wisdom...

Had ML’s but replaced every driver in both... just got tired of maintenance on them... 900 a panel.

I have a tube pre and it’s still there.... I’m not sure that 
1 The speakers may be too big for my room
2 The tweets or xover are going south
3  I certainly dont have enough power and that may fix it
4 the room is odd in shape and a low ceiling 

I cannot remember if you told us what amplifier you are using.  I don't think the Parasound P6 preamp is going to be better than the McIntosh preamp.  It is definitely newer.  Oh yeah, you're using that Crown Class D amp.

When looking at current generation amps, the McIntosh will actually have pretty good resolution on the high frequencies, but it will be laid back in the midrange for sure.  The Parasound will have softer and rolled off highs in some speakers, but it will have good attack and slam in the midrange.  The choice between these two becomes a factor of personal taste and synergy between components.

As I said, my cousin has the Aerial 10T.  He has a very high resolution Krell preamp with silver XLR interconnect cabling.  Currently, he has Emotiva XPA-1 monoblocks, which we had to upgrade with Isoclean fuses to "take the edge off".  We also had to switch the speaker cables to solid-core Audioquest Type 8 with gold-plated spades.  This further helped that harshness.   As I have said, I am bringing down my Parasoiund JC1 amps (fully loaded with Furutech fuses) to see how they sound on the Aerial 10T's tomorrow.   I can send you my results.

I think the harsh edge on your 10T is due to two things.  One is the metal dome tweeter, which has a breakup/distortion slightly above the 20khz point.  This causes enough of a problem where the high frequencies can sound harsh/bright.  The second problem is the kevlar midrange, which also has a cone flex/breakup characteristic which can cause harshness/distortion in the low high frequencies.  I would keep your McIntosh C41 preamp for now and experiment with solid-core speaker cable and a different amp.

Mac 7100... now the crown... only because I have to. I know the Crown isn’t what I need, just what I have! 

Aux....

I thank you for your help as all the other members. I am actually thinking of driving to NC to listen to. Few pair of speakers... Motion 60’s and the 7T’s.  I LOVE a huge sound stage and punch... I am a musician...
