Magico S5 Speaker - SET UP ADVICE PLEASE - Tow-In - Etc.

Just bought a pair of S3   The owners manual was a good start. Do you have one?

No need for toe in. Those speakers are well designed and actually have good wide even dispersion. Just point them straight ahead for optimal Soundstage.

Didn't your dealer help you set them up? At his margin he should---that's part of what you paid for, dealer service.

I wish I bought new or rather could afforded to have new. More like 40% off which I couldn't find any dealer offing for such a respected speaker. Bought from original owner who owns a few houses and these were at a house he basically moved out of a few years ago on other side of country and only went there once in a while. Because he had used so little use and was never there anymore he had shipped to Magico and had gone through and service and test, etc. and held their till sold which was great but no manual and no dealer set. I think I've got a poor match somewhere - or set up wrong - wicked bright - maybe my cables or set up or something. I need help. Wish I had a dealer but any Magico owner please help me. I know these are great speakers just not sounding great yet? So darn bright :( something wrong here / bad cable match or something but I can hear the greatness in there 

What are best cables for taming brightness?? That are not stupid expensive - I believe in cables but not paying more than my speakers or DAC or amp?

i have HiDiamond D8 Speaker Cables that are copper and pretty smooth and decent. Not Nordost Oden but compitant decent SC's.

i am running with no Preamp going direct from my Bricasti M1SE to my Pass Labs X350.5.

The IC I am using is single ended RCA Verestarr Grand Illusion Signature 2m and this is a very nice IC - not cheap and a bit warm very nice with my other speakers. 

Power cable for DAC and Preamp is the also very nice matching Verestarr Grand Illusion II 2m. These are nice and open sounding PC's - not cheap but used not insane either.

i don't see any apparent / glaring weeklink?? 

Im thinking getting a tube preamp.
BAT VK-32SE and maybe a warmer not hyper detailed IC - maybe Cardas Golden Reference or Kubaba Sosna Facination - both balanced - I chose these because a bit warm and phat but not too much so but that's where my brain is at which proves I need help?

any idea guys? Is a MIT cable better - so many models.

The way sound now is sort like you would think Spectral amps sound without MIT cables just too much of a good thing - the highs are to the heavens but too much. It lacks balance - meat - blood - midrange - earth - needs all of it.

Help !!!
