@soix is correct in letter your Sopra's settle in. I listened to my Sopra 2's for about 6 months before they settled in. I was maybe listening 2 hours per day for 5 days per week. So that's about 40 hours a month and 240 hours over 6 months. The brightness definitely settles out and I understand the brightness concern right out of the gate. But they definitely burn that off and become a lot more delicate and precise rather than sharp and direct the first few hundred hours. Can't comment on cable changes as I have just run my Rocket 88's and that's it.
Cable upgrade
I was contemplating a cable change as I recently purchased new speakers, Focal Sopra 1’s. I am running McIntosh MC275’s (mono-blocked). I currently have Goertz MI 2 Veracity cables. I wonder if anyone has experience with Nordost Frey2’s in a similar type system, i.e. tube amps? As the Goertz’s are also of a ’flat wire’ build type, they might be somewhat analogous and carry similar characteristics, with the Nordost doing so at a higher level?
I made a huge jump in speaker capabilities and wonder if I should also upgrade to a higher-level speaker cable also. The dealer listened to my system after we set the speakers, and he stated knowing what he knows about the Focal’s, he felt I was leaving something on the table as to the highs with my current cables. He felt the highs sounded ’ truncated’ and not as open/airy. Yes, I know he’s probably trying to upsell, but he’s been pretty honest in my dealings with him.
I have read many threads here regarding the Frey2's, and they appear to be well liked.
TIA
