Default Hiraga amplifier

Hi All,

I have a opportunity to buy original Hiraga class A amplifier.

Any idea how much these are worth?

How does it standup against current production solid state amps?

Has anyone compared it to AKSA or Nelson Pass Aleph?

I plan to use the amp for bass duties.

Thanks
Rafal

To know how much these are worth you can look on Ebay.

I can not compare it to AKSA or Nelson Pass Aleph, but i can to much other amps. The Hiraga sounds very, very good and it's worth the money they ask on Ebay.

I have one and i will never sell it!

Hello Rafal,

I agree with Wim.
Also remember that its output impedance is highish (IIRC a dampening factor of about 12) so keep that in mind when using it for low frequencies only.

When buying, try to assess the condition of the PSU capacitors and look for non-original replacement output transistors.

Good luck,

Johan

I searched on ebay but cannot find any recently completed auctions.

Where there several versions with different power output?

If so how do you know what is the power output of the model I am looking at?

The amp has black chassis without aluminum face plate. Some photos I seen have aluminum face plate?

Thanks
Rafal

Hello Rafal,

There have been 2 versions: a 20W and a 30W version. IIRC one was called ClassA and the other LeClassA: unfortunately I don't know which is which.

I think I've seen prices over here ranging from about 1000 euro to silly money. Again if in good condition they're worth it.

Johan

The 30 watt version has a much larger powersupply, you should go for that one.

Hi Rafalc,

I don't think I'd be using a Hiraga amp for BASS duties!! Two reasons; it's not all that powerful, and it's possible you really need about 50W for bass, and secondly, these amplifiers have a sublime, exquisite midrange and top end, and this perhaps is where it might best be utilized.

Cheers,

Hugh

rafalc, you find them on Ebay when you search in Germany (Duitsland).

For prices between 1000 euro and 2000 euro.

What is your seller asking for it?

I agree with Hugh. Mr Hiraga always was a fan of high-efficiency speakers and that is reflected in his amplifier designs. Normally I would not hesitate to recommend any of his designs, except for bass/subwoofer duty. You should use the Hiraga for mid/high, that's where they are unbeatable. Get a more powerfull one for the bass.
