Will the Nord amps drive my difficult 2 Ohm speakers, what about Electrostatic speakers?
Yes, We have many customers ask this and are now running Nord amps with great success. The amps deliver a maximum 28A of current for each channel so will drive pretty much anything. They work exceptionally well with Electrostatic speakers.
Will Nord Amps work with Subwoofers, how do I connect?
NC500, NCx500, NC1200, Purifi class D amps can all be connected at high level to a Sub Woofer in the normal way. Ice Power can not.

How do you manage warranty?

What is an Input Buffer and do I need One.
Every Power Amp has an input buffer, most are fixed. The Nord NC500 and Purifi range has a separate buffer that plugs into the Amp Module so that OEM's like us can improve and tailor the sound of our Amps.
Its job is to take the very small signal from your source and match impedance and increase the level being fed into the Amp module. This is best place to change and improve the sound quality.
Why choose the MKII REV D spec input buffer?
The Nord REV D buffer uses discrete op amps and Voltage regulators. It adds tonal density and gives the amp a richer more Class A sound. Dynamics are also improved partly due to the onboard Voltage regulators.
Can I change Op Amps at a later date? What is the sound signiture of each?
Yes they are relatively easy to swap with care. Just need to get pin one the correct way and all the pins lined up. They are pretty delicate especially the Sonic Imagery 994 so you just have to be careful. We recommend a skilled technician carry this out (H&S requirements) Sound differences click here.
Where are your amps made?
We manufacture everything in house here in the UK with module sourced from Hypex Purifi etc. in EU and Op amps from the USA.
What is the SE version of Amps
The SE version is only a upgrade to our Japanese SE case, which has better finish and fit with better looks. Also comes with switchable front LED ON OFF DIM
What is the 12V trigger option for?
It works with a pre amp that has a 12V trigger output and will automatically turn the Nord power amp on when the pre amp is turned on. When the pre amp is not in use the amp is completly off not even the trigger is using any power.
How can I pay? What is the lead time?
You can pay by Credit Card PayPal or TT to our Bank.
Our lead time is within 2 weeks. We achieve this 97% of the time only in exceptional circumstances when our suppliers let us down do we miss. We don't over promise.
The case gets warm. I thought Class D ran cool. Is this normal?
Yes, the case acts as a heat sink unlike class A A/B amps which have large heat sinks that expel heat out of the case from the side or slots above the heatsink.The modules are mechanically and thermally connected to the case. They can reach temperatures of 42 degrees on a 25 degree hot day. The base plates run at about 60 degrees well under the max of 90 degrees.
Is there a “Burn in Period” and do they have to warm up?
Yes, customers have reported improvements with running time. The biggest improvement comes after about 10-20 hours. They should sound great out or the box. There is a small warm up period about half an hour.
If I purchase a standard Amp can I upgrade to the MKII REV D version at a later date? Can I DIY upgrade
Yes, the Nord input buffer board has been designed to plug & play directly into the standard amp. The whole process should take about 15-20 minutes and is pretty easy for any customer to DIY it themselfs
Why should I buy the Mono Blocks over the stereo version? Do they sound the same?
Personal preference and how it fits in your configuration. There is no sonic advantage to the Mono Blocks the stereo has the exact same components as the stereo, they just have two cases etc and take longer to build.
Do you sell through Dealers?
Not really, we have a few but we mainly sell direct. This way your save 60-80% on dealer and distributor margins.
