Input Buffer PCB board final design ordered
So we have ordered our first batch of PCB's delivery due around the 12th Jan. Testing of different OP Amps continues over Christmas. The Sparkos is still my favourite however a friend prefered the Burson today. I'm hoping to carry out some more controlled tests in the coming days with the aim of defining there sonic traits. #Amp
Final design of the new input buffer board
The NCore NC500 is an OEM product used by manufactures of high end audio amplifiers and can be found in some very large companies high end product lines. It differs from the NCore NC400 as it has no input circuitry. This is where manufactures can add there own "house sound". So we at iQ have produced our own which will be capable of taking vaurious op amps and Hypex's upgraded discrete voltage regulators, including discrete op amp offerings from Burson and Sparkos Labs. This
Rev A protptype Hypex Input Buffer board arrives.
Now if the NC500 did not already outperfom the NCore NC400 DIY module from Hypex well this should seal it! Rev A protptype Hypex Input Buffer board arrives today with standard LM4562 inserted into the 8 pin DIP socket. Sound testing using the Burson V5 and Sparkos Labs discrete OP Amps to follow. The Hypex discrete Voltage regulators already fitted. Hypex Electronics BV - HxR12The HPR12/HNR12 are high performance voltage regulators targeted at performance-critical audio appli
Prototype Nord Input Buffer Board!
To say I'm bown away would be an understatement, Its taken the standard Nord One NCore NC500 (pretty much same sound as the NCore NC400) to another level. The standard version is superb, highly powerful and acurate and equualed the Abrahamsen beacuse it was different more powerful, cleaner. If you asked me to sit in an average room which you would listen to for hour on end I would pick the Abrahamsen, full stop. Not now, after trying the new input buffer board. We tried both
