Supernait - Are my ears kidding me?

Was trying real hard to find an integrated amp that could do better justice to my humble Vandersteen 2CEsig2. Ex Amp was MARANTZ PM15S1. Liked the way this MARANTZ dealt w vocals so much that was prepared to over look its limited bass extension and thin sound.

Mean time auditioned
- Ayre 7xe
- BAT vx300
- Marantz PM11S1
- NAD M3
- Luxman L-590u Class A
- Luxman L-505u Class AB
- Musical Fidelity A5.5
- Musical Fidelity A1

Somehow ALL (IMHO) could not justify the hudge jump in budget. Until my dealer called me in for the supernait audition - I was sold after 2 times audition. Now my system config as below -

CDP1: Vintage MARANTZ CD15
CDP2: MARANTZ DV4001

AMP: SUPERNAIT
TUBE BUFFER: MUSICAL FIDELITY X-10v3

SPEAKERS: Vandersteen 2CEsig2
Interconnects/SPK cables: Nordost Wyrewizard+Dreamcaster

++OBSERVATION++
1. Supernait too loud
Aware tis sound like a no brainer but its not about the volume knob. just that right now, its really difficult to listen to a whole song completely ie. everything sounds so so loud BUT nice. It seems all the instruments, back grounds, vocals are occupying the same presence in the music. Something I never experience before. Its almost 3 dimensional ie. sound stage has dramatically expanded but compared to my MARANTZ PM15S1, I can usually go all the way past 60% of the volume BUT Supernait - max I can go is 30% before it really gets too loud. (come one 30%??) Mindbearing MARANTZ PM15S1 is 90w per channel at 8ohms - above Supernait!

2. EVERYTHING IS GOOD BUT ....
Observations below made against MARANTZ PM15S1 only. Sound stage has dramatically expanded ie. music now fills the whole room. Rythmn has intensified ie. Has never heard my jazz pieces sound soooosooo fast. There is a 'POP' colour to almost all my CDs now. Maybe this is the PRAT symptoms that many forums have used to describe NAIM sound.

3. A little volume goes a long way
75mv of input sensitivities goes a really long way compared to 240mv in MARANTZ PM15S1 but its a little too fast too furious. One wld be suprised at how much the initial adjustments from 6 to 9 o'clock actually increases the volume. Dealer informed me that this actually a good point as eqpt like MP3 wld do well under such competent volumes.

4. SOMETHING MISSING ....
Can't put a thumb to it ... but the initial impact that DRAWS me to the supernaim ie. the way it presents the music (i hv never come across such presentation) seems to be lacking something...I dun know what. It SURPASSES much to the MARANTZ PM15S1 in many aspects of displaying music but somehow it appears COLD in the way music reaches me. The same CD (the song that I hear so many times) seems to be more competent in all instruments but the vocals just does not connect in the same way the MARANTZ did. EACH INSTRUMENTS/VOCALS/EFFECTS IN ANY SONG SEEMS TO BE FIGHTING FOR ATTENTION AT THE SAME TIME - COMMING TOGETHER AND HAVING THE SAME LOUDNESS (yes i mean certain effects that i could only hear in the back ground in the marantz pm15s1 can now be heard very clearly with supernait but ... its like all the notes/instruments are fighting for the listerner 's attention albeit in an orderly yet forceful manner...)

CONCLUSION
---
I reflected the above to the dealer and the intial suggestion (to my suprise) was to plug the power directly into the wall socket and not via the transformer which am using for my 100volts CDP. To my suprised again, tis indeed cured the loudness issue somewhat BUT not all -dun know why.

Am seriously pondering if Supernait and Vandersteen 2ceSig2 r really a good match. I love these speakers and not gonna change them and the amp shld compliment them instead!

Perplexed now....and also read many forums on NAIM and many owners of NAIM products actually claim that putting the AMP away (not in between) the speakers will actually improve the sound of teh speakers? huh... any way attaching the pictures of my set up as below....
