Do Power Cords make a difference on the NHB-18NS Preamp?

[manjy]

Hi,

Considering that the NHB-18NS is a Battery Powered preamp and in battery mode the AC power is disconnected from the unit, do power cords make a difference? They should not but I'm wondering if any one has tried with different cords.

Thanks.

A waste of money IMO. Sending the unit to CH for an upgrade would be a much more cost effective solution IMO (unless you have the latest spec).

they do. not sure why.

i've tried moving my Absolute Fidelity power cord to another source component and putting a generic power cord on my 18NS a number of times, then get reminded that it matters. i think it's just an indication of just how pure it is. and how far into the music that the 18NS takes you.

but only recommend that you try it yourself and see. maybe try it a few times.

if it's a choice between a power cord and MK2 upgrade, then i agree. but no doubt a better power cord can matter.

I have to try it on the 18NS/458 that I have at home.

Hi, I will get a generic power cord and try it over the next few days.

Hi, sending the pre back to Switzerland from my location is a royal PITA and hence I haven't considered it.
Please do try it on your pre and let me know how it goes. Thanks.

I agree with Mike, they absolutely do make a difference and I absolutely don’t understand why…

my GUESS is that this is related to the grounding thing. a better power cord grounds the chassis and power supply circuit more completely, and it does effect everything. there could also be battery related optimization going on.....calming the charging circuit.

my battery powered CS Port phono is the same way. the power cord matters.

I vote yes
In fact more so than other cords.

Why is CH?not Dartzeel?

Why is CH?not Dartzeel?

CH = Switzerland (not CH Precision in this case).

The letters CH appearing on Swiss cars and in internet addresses stand for the Latin words Confoederatio Helvetica, meaning Swiss Confederation. Helvetica is a widely used sans-serif typeface developed in Switzerland in 1957.

I think you are correct. I actually grounded the 18NS power supply case, to a Shunyata ALTAIRA and Denali V2, with great results.
