Great Northern Sound Company is based in Stillwater, Minnesota. Founded by ex-Wadia engineer Steve Huntley (he also did time with Audio Research and CAL), it’s a serious high-end dealership with an equally serious sideline in modifying products – including those they sell. Which in itself should give you pause for thought. After all, why would the likes of Wadia, Aesthetix or Resolution Audio retain these guys as dealers when the first thing they do is go inside the products those companies make. That’s a pretty emphatic vote of confidence in the work they do. When it comes to the 861, GNSC also offer three levels of modification –
Standard, Reference and Statement:
The
Standard upgrade costs $950
(plus shipping and VAT) and
includes the use of proprietary noise reduction devices in the power supplies, the removal of current limiting on the digital and analogue regulators, changes to the analogue filter section and upgrades to the critical analogue bypass caps.
GNSC will need the player for around two weeks in order to complete the work.
The
Reference package adds a completely reworked power supply, with Black Gate filter capacitors throughout, high-speed rectification additional local reservoir capacitance and the installation of Bybee noise reduction devices. Key signal path components are upgraded and high-quality output transformers are fitted, improving isolation from the amplification and preventing the passage of digital/RF noise into the system. Finally, extensive mechanical damping of the mechanism, boards and chassis is carried out. Total cost of this is $2000
(again, plus shipping and VAT) and the mods take around three weeks.
The
Statement level modifications,
as carried out on my machine, cost $3500 (plus shipping and VAT) and do all of the above, but add considerable additional local reservoir capacitors and significantly improved regulators. Analogue section caps are replaced by larger and higher quality. The Blackgates throughout are paralleled to improve filtering – making for a total of nine new caps in the main digital supply alone.
The AC input receives custom filtering and a special Bybee purifier with silver leads is used in the digital signal path. The mechanical damping applied to the unit is far more extensive, taking some 12 hours to complete, and all diodes, regulators and the DAC board, receive a layer of MusiCote. ERS RF absorbent material is also used internally, to quiet components and prevent noise radiation. The Statement mods demand a four week stay for your machine in Minnesota.
