<<SOLD>>

I know Jupiter Lee of Jupiter Audio Research and followed with interest his extensive modifications to the stock Sennheiser HD650. After multiple iterations, his completed modification, the JAR650, arrived IMS in mid-2018, along with a stock HD650 for comparison purposes. After intensive comparisons of the JAR650 vs the HD650, I posted a review (linked below) praising the JAR650 for improving virtually everything that is good about the stock HD650 (a headphone whose sonics I admire):

Subsequently, Jupiter further revised the mods based on user feedback, and I received the fully updated JAR650 Q1 of 2019. IMO this final-form JAR650 took the original improvements a bit further and represents a significant sonic upgrade of the stock HP. I'm not aware of any revisions to the JAR650 since that time.

I have multiple headphones and thus use any one headphone infrequently; I put no more than 25-30 hours on this JAR650. Regarding cables, in my review of the JAR650 I used a stock Sennheiser HD650 cable, which I no longer have. I replaced it with a good 10 foot Periapt balanced cable.

I have ~$550 total in this JAR650. My sell price is $375: this includes the JAR650 + cable, as well Paypal fees and shipping w/in CONUS only.

Please, no trades or lowballs.
