We can assemble completed NC400 amps for you and also modify your assembled amps with our latest updates.
The most important things to get better sound in a NC400 build are:
1. Use an audiophile fuse....makes a big difference, much more full, and lower distortion....we sell the Furutech fuses.
2. Bypass the binding posts using my binding post bypass system. Depending on the connector you use can vary from better to way better.
3. Bypass the output connectors on the NC400 board. Makes the amps much more full and palpable. We remove the stock connectors and replace them with PCOCC 16 gauge wire that you solder the output wire to.
4. Change all of the Polyester .68uf output filter caps to pairs of modded .33 uf Polyprop caps. Lowers noise way down....Way more transparent. Its as if you scrubbed the noise away and it is sooooooooo much more palpable and real......amazing amount of space/reverb/air now. The Polyprop caps have the stock leads removed and replaced with 6N copper leads and the caps are marked for outside foil polarity. The caps are mounted so the outside foil is oriented to ground.
5. Use good IEC and input connectors.
6. Use good wire on the output (soldered to the new bypass connectors on the NC400 and run outside the amp and wrapped around the binding posts).
7. Add an AudioMagic Pulse Gen ZX to the input power (two if dual mono).
8. Exotic feet and damping
9. Balanced configuration. More air, more detail, more dynamic and more vivid
You do all the above and you have one super transparent amplifier.
Mods done to the modules (cap and output connector mod) will void the Hypex warrantee. However, the modded modues are not any less reliable than the stock modules......which are extremely reliable.
Pic of the NC400 output connector mod and the cap mod:
Pricing will depend on what kind of build/mod you want and what level of parts you want to use. We can source the chassis and parts or you can send me the chassis and parts. I charge $75 an hour for my labor.
For instance, say you already have an assembled amp but want our serious updates. We can do the connector mod and cap mod on your NC400 modules and drill holes in your chassis to run the wires outside and wrap around the binding posts for $300 ($100 for the 12 modded caps, $100 to install them and $100 to install the PCOCC jumpers, drill holes in the chassis, install grommets and install the output wire). Another $96 gets you Furutech fuses.
Assembly of a set of monos or a dual mono can be anywhere from 2-5 hours ($150-$375).
An example of an (all out) full assembly including parts cost:
2 mono chassis $175-$200?
Two Furutech FI-10 Gold IEC connectors $55
Two Furutech Gold FT-786F XLR input connectors $84
Dayton Binding posts (acting as clamps only) $35
14 gauge PCOCC litz Output wires $20
2 Furutech fuses $96
12 modified .33 Wima caps $100
install OCOCC output wire connectors, and run output wire through a grommet and wrap around the outside of the binding post
5 hours labor $375
Total $950 or so.....this does not include you sending me your modules and power supplies or return shipping.
Example of simple assembly:
2 Schurter IECs $3
2 Neutrik XLRs $12
2 sets Dayton posts $35
Labor $250 including running wires to outside of amp and wrapping around binding posts
Total $475 plus
We can do whatever you like. From simple to way out. The pricing above assumes the chassis are already punched or mostly punched for all the parts. If the chassis needs mucho drilling and work then the labor price goes up.
If you just want the 12 modified caps (6 pairs) for your own installation then it is $100.
