Dual Mila Woes. Distorted and shrill!

[goldstache]

So i have a dual Mila  (12av7)  built up and am wondering if what Im hearing is the aim of the design!
I have built NYD's One Bottle (6sn7) and it was lush with lots of low end.
My Mila is harsh and tinny, even compared to my apogee preamps on my convertor. 
I have tried running the Mic pre into conversion at +4 and -10, as well as line level,  and it has very little usable gain range.
It's more usable into mic(150ohm) input.  I figured it would impedance match better at line level(600)

I am using a beyer input transformer
200:20K
And an Edcor output transformer
10K:600

All my voltages are right on the nuts.  Layout is a little sloppy, but it's not really noisy.  The 1/4" input though shielded, has a bit of noise. 

Power supply is outboard.  The pre is in a 1 space 19"rack.

I can't seem to understand or see the error in my ways as to why its sounds so Nasally and unmusical.  I must have goofed.
Anyone with any insight?

All my parts are right (fingers crossed)
Thanks

A sloppy layout can cause very high frequency oscillation which can make the amp sound shrill.
