can it bee that audio research vsi 75 has lack of open highs/mid ?

thanks.
what are those teflon caps?
sorry but my english is not perfect.
what do you mean by: "Drive you nuts in speaker crossovers, but they sure sound good after a 24/7/14 face to face (2 whole weeks.)"
that i should leave the amp working constantly for  2weeks?

thanks.
i asked a friend of mine that is a very experienced technician in audio including tubes.
he said that teflon capacitors are the most reliable and quality caps, and it's isolated very good from heat and resonance.
i just wonder if it's the reason for relatively long time to break in.  

do you have one, or listen carefully to it?

first, i still don’t own this arc, just listened to it in a store.
have now :
crick audio integrated.
well tempered tt and arm.
monster alpha 2 cartridge.
speakers and phono stage are in a plan to upgrade.
right now kef speakers and SCHIIT MANI phono.
but i would not pay lot of intention to what i have today, since the only thing that will stay is the turntable.

i wish i could do it.
it’s of course the best way.
unfortunately shops here in my country don’t do those things.
so at the end i have to decide either buy it or let it go.

the country is Israel.
usually importers here import from those kind of items just few examples , and sometime only if you order it specially.

and what i heard in the store was on several speakers and oracle phono stage, TT German turntable( hope i remember the right brand) , don’t know which cartridge.

thanks.
i am planning an additional listening in the shop, and than make my final decision .

thanks, i will for sure consider it .

thanks.
we are not talking about the Ref 75SE, but the integrated vsi 75
