My source is a Naim NDX 2 powered by a Naim XPS (non-DR) power supply.
My headphone is a Focal Utopia with a Danacable Lazuli Reference cable (3 meter, unbalanced).
It is now time for me to buy a dedicated headphone amplifier. (I am not interested in purchasing a headphone amplifier/DAC combo.)
I would like the headphone amplifier to have a form factor similar to the Naim NDX 2. (I am not interested in purchasing a large headphone amplifier with tubes.)
Finally, the headphone amplifier must have the scalability and class of the NDX 2 and the Focal Utopia headphone.
A dealer in Canada offered me a home demo of the Niimbus HPA US 4+ headphone amplifier/preamplifier. After a quick search I learned Niimbus is a brand made by Lake People in Germany. Niimbus is part of their “Ultimate Series”. They also make a series branded Violectric, as well as, various pro audio gear.
The Niimbus HPA US 4+ has a list price of $5,999.95 US funds.
The headphone amplifier/preamplifier measures 351mm x 82mm x 275mm.
I accepted my dealer’s offer to home demo the Niimbus HPA US 4+.
When I received the amplifier I connected the Naim NDX 2 to the Niimbus HPA US 4+ with a set of WyWires Silver RCA interconnects (1 meter).
The WyWires interconnects are made of 100% copper Litz wire and they deliver high bandwidth, stable resistance and frequency extension. As promised, they “get out of the way”.
I pasted a few FLAC files onto a USB thumb drive… I plugged the thumb drive into the Naim NDX 2… I pressed play…
I think there is synergy between the Naim NDX 2, the Niimbus HPA US 4+ and the Focal Utopia Headphones.
I am really enjoying this.
I will post more thoughts after the set-up settles down.
