@arafiq They are very, very different speakers tonally. I also have a lot of affinity for Joseph Audio and have heard all of his current speakers. I would say that Borresen is brutally more honest in the midrange. While I love the detail, tonal balance, and slightly warm delivery of Joseph, it is not the most revealing speaker. I don’t mean that in a bad way, they are simply just lovely speakers. I’ve actually reached out to Jeff Joseph to see if I could carry them since I know he doesn’t have any representation out in the Minneapolis region.
Joseph will sound more full, a bit bloomier than the X3. Switching to the X3 may be a bit jarring, and you may find them to be drier and tipped up. They deliver with a bit more contrast. They are very fast across the board, but also, being on the bottom of the Borresen line, more fatiguing. While it has the famous Borresen tweeter, the remainder of the speaker is made of cheaper components. While the tonality of the X3 is very much in the Borresen sonic signature, it is much more brash than the Z series, let alone the 0 series. It is a great speaker for those who love the Borresen sound and can only afford to spend $11-12K.
Your Perspective2 Graphene are great performers and it would likely be a sideways move to go to the X3 unless you’re craving a completely different sonic signature. Both speakers have very different strengths and weaknesses, and you will be trading one set for another. I hope that makes sense.
I’ve noticed a pair of the Perspective2 Graphene on USAM and have considered making the seller an offer. I own the Borresen 02, so that should show how much respect I have for Joseph despite their known weaknesses.
