Mccormack DNA-1 describe the sound characteristics

I am using Alon II speakers with the black orpheois bi-wired. The speakers are 88db I think. I took the jolida out of the equation and used my Luxman reciever as a tuner, but still the FM radio station music is lacking in bass & mids. The music just sounds slanted towards the high un-involving. I prefferred my B&K ST202 paired with B&K Pro 10MC pre. I've been over the wiring multiple times. I recently had a marathon burn-in of the Morrow interconnects 10+ days 24/7.

My debate is do I through 500 -750 into the amp? Could there be something wrong with the pre??//
The tube swapping in the pre did not seem to make a significant sound difference. Mazda NOS 12AT7, then Sylvania 12At 7 WA from the 50 -60s, and then the stock chinese tubes... They each should have had a significant sound difference, shouldn't they???

i sold the pro 10, but the limited minutes using it with the mccormack I noticed i didn't have to turn the volume more than a 1/4 turn before I was at high volume. As for the sound signature, high end more detailed & the bass was about thee same as it is now (can't feel at moderate high volume). I should have played it longer.

I have morrow interconnects which I suspected originally, but now have well over 250hrs. on them. Can they still be bright and not allow full music through?

I reversed the speaker wires on the amp side placing the positive to the negative labeled connection. I listened to one song and found the sound to have a little more bass and slightly fuller.. with a little less brightness. Could the amp be wired incorrectly? The TAD isn't phase inverting like some Cj pres... All other interconnect connections are as labeled. The other course thing about the amp,the left side heat sinks are black while the right side has a purplish hue. I would think both side should genrate similar heat and would be colored in the same manner??

After many more hours of burning in all components especially the morrow cables I am beginning to hear the sound I was looking for.. I also purchased a pair of NOS Mullard tubes which brought back more of the warmth I was missing.

After thinking back on my previous system B&K ST202 with Pro10MC pre the bass was boomy and bloated. My ears were accustomed to poor bass reproduction that was boomy and bloated. The bass I hear now is accurate. I even stopped by a local stereo shop to listen to the same cd's that I had at home and the sound was the same as the more expensive Mcintosh (spelling) B&W speaker combinations.

I connected the speakers to my luxman receiver while maintaining the same configuration on the speaker terminals. Connecting the Jolida CD palyer to the auxillary input on the receiver the sound is full-very nice. So this verifies the speakers are connected correctly as well as the cd player connection is a-ok.

Now how do I challenge the pre-amp, can I connect the pre-amp to the aux input on the reciever then connect the cd player to the pre-amp????

I beginning to think my problem is the cumlative effect of an amp that is slightly forward in presentation as well as having exceptional detailed highs combined with speakers which also lend themselves to being more forward, adding to the mix a TAD 150 pre-amp with NOS Mazda tubes which are known to be detailed on the top end..... Electronically nothing is wrong,, just the wrong combination....

So what to do, I am thinking of exchanging the Mazda tubes for Mullards and see what happens. I am also looking forward to a SMC upgrade
