Norber Custom floorstanding loudspeakers

Withdrawn by consignee. Older custom speakers by Steven Norber (founder and principal of PranaFidelity). Recently checked out and okee-dokeed by Mr. Norber.

On consignment. Asking $6800 obo. Full range, nicely voiced as Steven’s speakers always are.

From the manufacturer:

The speakers are a full range, 3-way design utilizing the top grade 3 layer “W” cone drivers from Focal for the midrange and woofer. The tweeter is from Accuton, and as one can see from the photo, is positioned between the dual midrange drivers in a D’Appolito configuration.
The cabinet is divided into 4 compartments: one for the woofer and its crossover, one for the MTM drivers, and a split rear section that is accessible
through a removable rear panel with the midrange and tweeter crossovers located in each of these sections.
The crossover uses correspondingly superior parts with film/foil capacitors,metalized polypropylene capacitors, and non-inductive resistors. All series
connected coils are air core types, DCR specified to maintain correct Q alignment.
The speaker is phase corrected with all drivers connected in phase and presents an impedance compensated 8 Ohm load to the amplifier.
The efficiency at 1 watt/1 meter = 88dB.
The finish is Birch, however this real wood veneer (which was catalyst sealed after being applied) must have come from a batch that was not properly dried, and after only several months developed small cracks on the surface. There are no signs of the veneer lifting anywhere on the cabinet, and the cracks have not grown in size or number since they appeared. That said, a skilled woodworker who knows how to hand sand to smooth and reseal the finish would be required for an as new appearance.

Even better, might be to consider re-veneering the cabinets. This is not an unrealistic alternative, given the machine screw mounting of the drivers.

In addition, as skeptical as I am of some of the “tweaks” out there in the (often other worldly) world of high-end audio, the customer insisted upon applying Marigo Tuning Dots and damping strips to the driver baskets and cabinet sides. Dutifully, I went to his home, removed the drivers, applied the dots and strips, replaced the drivers, placed the larger dots on the external surface of the cabinet’s side panels–and as much as I wanted to not hear an improvement, I did.

The difference was not just different, but, in fact, an improvement. The individual who purchases these speakers will be assured of purchasing a speaker that will compete with any on the market at $20-25K.

Edge M12 monoblock amplifiers

Withdrawn by consignee. Upgraded Edge M12 amplifiers (a pair, one for each channel). Original MSRP $13,600, we were asking $8000 obo. This pair is similar in performance to Edge’s later NL series amplifiers, but in a simpler chassis. Recently checked by Edge amplifier designer, who originally sold and upgraded these amps.

The M12 is a dual chassis, quad transformer amplifier (a power supply for each half of the sine wave, for each channel). It is the precursor to the laser biased NL series monoblocks and remains a formidable contender with the newest designs on the market.

While the transformers on the NL monoblocks are universal (multi-tapped 50/60 Hz) and superior with respect to addressing anomalies on the AC line, the sonic performance on a clean AC line with these older M series amplifiers is superb.

Please note: the transformers in the M12 are specified for 110/120 VAC @ 60 Hz only

The Edge sound is even across the frequency range, clean and fast with good detail and harmonic resolution, without being lean or grainy.
