"Higher Fidelity Ind." - any info, please?

This company manufactured high-end boxes in early 90th. Any information about names, history, patents would be highly appreciated. Thank you.

p.s. Higher fidelity 138 monoblocks were used by Van der Hul in his reference system

It looks like they used Hawksford-type of error correction in output stage – so called ‘triacting circuit’

Patent search gave no result

Some booklets can be found here and there .

I've just picked up an integrated amp by Higher Fidelity Ind - Century Series 2K3.

Anyone know anything about it? Triacting Circuit again.

Doesn't like your usual DAC input voltages - too much gain in the amp.

Has unusual pre-amp stage - switch in any input and they all play at the same time. Perhaps a very simple pre section, passive perhaps?

Picked it up for bargain price - was sold as for repair as distortion was reported. A fuse had blown on just one side of the power to the caps so I guess that's all it was as it's playing perfectly.

Any info would be greatly appreciated although I have a feeling I have seen a review of it myself in my old hifi mags - will post anything I find up too.

I friend of mine has one on a Medea and an Allegria.
It sounds just fine.

nat8808 · 29th July 2011, 12:30 PM

Weiss Medea and your Sonics Allegrias? That's good company for the amp..

Certainly sounding good into my B&W 805 Matrix from Tandberg 3001A Tuner but need to adjust output level on my Manley Junior DAC to get it to be usable - is bit loud even on the first click of the volume knob. Could be there's an issue with it of course - will have to find the review in Hifi News I'm sure I have..

Just to update - my 2K3 is sounding superb. Excellent wide soundstage with no harshness that I can hear, a fast amp too with good power in the bass.

I keep it on standby so it's been constantly powered for the last 2 months. Definately what it needs..

Still would like to find any info on it if anyone has some..

Hi
Am currently using the EQ-3003 MM/MC RIAA from this company, and simply love it. Not a simple design. When I bought it (from Germany) i serched the net for info, but found very little. I have a German Hi-Fi magazine with a raving review of my preamp, and also found a PDF brochure with different products by "higher Fidelity". Will try to post here if I find it.
