LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING

something is drastically wrong.  the Delos is an exceptional sounding cartridge and is not at all bright or shrill.

if you tried loading at 200 ohms, make sure the VTF is dead on 1.75 grams and your headshell is perfectly level to the platter when the cartridge is in the groove, something is wrong with the cartridge or installation.  
have you checked the phase of the lead wires?  

i just did a comparison between my lyra delos and similarily priced ortofon cadenza blue.  have had the delos in my system for a few months.  
used to love the sound of the Cadenza Blue.  The Lyra has a much more dynamic colorful sound with a larger sound stage.  
i loved the sound of the Ortofon but it now sounds flat and dull by comparison.  
The Delos is the real deal.  note: Delos has 60 hrs.  

For reference I just learned something about my Delos the other night-
A new recording was sounding especially bad- edgy and not fun to listen to.
I experimented with everything.  
I made a nice improvement by lowering the gain on my phono preamp for the Delos to 52db down from 58db.
58db is just a touch too much for the .6mv Delos.
52 db is usually too little gain for a .6mv cartridge but it sounds fantastic, much better.  Did not lose any dynamics either which was a surprise.    

So it appears that the Delos likes gain on the low side for its output. 
Try it if you haven't already.  

Finally nailed the Delos after months of tuning.
learned previously- 
*likes lower gain than usual
*alignment is critical
*level the top of the headshell, tonearm level is not relevant.  

today i finally tried a low capacitance phono cable (50pf per meter). 
this allowed me to set the loading at 475 ohms, per the manual cable capacitance and loading are very much related.  
my previous cable was 110 pf which liked 200 ohms loading.  
the cartridge sounds better, its best actually, with 50pf cables and 475 ohm loading.  sound is cleaner, no trace of ringing, more neutral and natural.  
a very complicated cartridge that may not sound good with typical MC cartridge settings.
