Reason for sale: This is my last treasure from my time in this hobby - an HE-90 that I've run with the OG DIY T2, Kerry DIY T2, Mjolnir Carbon CC, Megatron, and a few others - all without an adapter!
Plug: Stax
Cable: Stax 99.9999% copper, silver-coated
Bias Voltage: 580V
5M Ballast Resistor: No
Description: Transducers cleaned, original dust covers serviced (not replaced) by ES Labs, housing and box by ES Labs.
Performance: Many later-production HE-90’s need an adapter with an additional 5M ballast resistor (Sennheiser specified 500V bias voltage and a 10M resistor, versus Stax Pro Bias 5-pin, which is 580V and 5M). Unfortunately, this limits the dynamic potential of the HE-90 transducer on Stax Pro Bias, but is necessary to prevent the diaphragm from sticking to the stators.
The pair listed here runs perfectly without additional ballast when plugged into Kerry’s T2 (or the Mjolnir Carbon CC), at any volume, providing for incredible bass and dynamics - meaning it will run just fine plugged directly into any lesser Stax Pro Bias amp - no Aristaeus, HEV-90, or performance-sucking adapter needed!
Additionally, the OEM copper Sennheiser cable is prone to corrosion and also limits detail retrieval. The latest Stax cable reveals Shangri-La SR levels of detail, and then some. The dust covers are also a concern on the HE-90, but ES Labs did an incredible job cleaning the transducers and micro-patching the dustcovers, which is extremely meticulous and time consuming work.
Preferences: Sale within Canada or North America is strongly preferred, dealing with members I already know well and have dealt with before is also preferred, so I likely won't respond to every inquiry - I apologize in advance. Shipping via UPS is included in the listed price.
