Until my man cave is finished, my main amplifier in the living room is a Hitachi HMA-8500 Mk II produced in 1985. It's a traditional class AB linear power amplifier, but it's
biased for class A...

Myself (or the sellers for that matter) only suggest that they are based of that design. :) Thank you for the input. It looks nice and tidy - and quality parts are used as far as I can see. It could...

Anyone who has had some experience with either of these two Chinese preamps based of the famous Mark JC2 circuit?

They look a bit different inside. One with very many capacitors - the other very...

I have a cottage/cabin up in the mountains where I have my 7510. It works as the heart of my stereo system there connected to a Hitachi HA-5700 integrated from 1979 and a pair of JBL 3 way speakers...

Hi Paul. The screen looks nice on that thing. :carrot: I see it has output amplitude of "only" 2.0VRMS, but otherwise looks good, thanks.

Hi Johnny. Only aesthetic reason really. The Nad had a plastic front and looked little bit cheap for the price, and the master series M12 with a bluesound module seemed a little over the top in terms...

Thanks guys for your different input. Came to a conclusion and have just ordered the Teac NT-505. It has 2 optical inputs (one 'normal' at the back and a Mini Toslink-Toslink on the front panel),...

@ Poldark; I agree - I have no problem getting decent volume levels close to max with the dac alone. The Marantz HD-DAC1 dac I have put out 2,3V RMS maximum. But I found I get a much more smooth...

The power amp is Hitachi HMA-8500 Mk II (rca input 47 kΩ, 1 V RMS).

Don't really have a budget. But let's say up to £ 1000 maybe.

Looking for a dac that will work good as a pre also. Need 2 optical inputs, coax and usb from computer - and it has to be able to play MQA from Tidal. I don't need analog inputs and phono input.

The RA 1572 is traditional class AB, the 1572 power amp is class D as I understand it.

As I understand the class D amp Rotel RB-1572 has been around since 2009. But now there seem to be a V.2, or mk 2 version.

Can't find any real reviews or tests...

Most of it has excellent build quality and reliability. I recently bought a Hitachi HMA-8500 Mk II power amp that was produced in min 80s. Hitachi is a brand that is little bit overlooked, and the...

I am so happy we are all friends again now. :rfl:

This thread turned into way more than I expected, and I am happy about it; because just like Marco pointed out - I (and I think others) learnt...

Not opened it up yet. Need to find time in winter to check it and possibly change all caps. Fantastic old dual power supply amp that deserves to live on. :)



Yes, fire is what came to my mind...

He is of the opinion it is better for the amp to do so, from a durability point of view. Not that is sounds better. ;)

Know a guy who bought a NAD 216 power amp in 1995 and has never turned it off for the past 21 years. He is of the opinion that it is better. The 216 still works perfectly and he has never had any...

I am a 3 way fan. But resently had a listen to the Klipsch Reference Premiere RP-280F which is a 2 way construction, and they sounded incredible to my ears. 1 horn and 2 x 8" bass/midrange.

Not...

x 2!

I don't use the treble and bass knobs. But have an old pre amp (NAD 1130) from late 80'ies which I use deliberately because it both have loudness button and bass eq button.

The loudness button...

I agree. Just need to find motivation.



Yes, that is next step now. I will take out all 5 drivers and line them up on the table together with crossover. Cable it all up with temporary cables...

In it's own enclosure. The cables don't touch, and the damping material don't touch. I was also thinking about this, so tested it not installed, just the driver on a chair playing music.

The...

Had the crossover checked. Nothing wrong with it. So I changed the crossovers over between cabinets. It didn't fix anything. But confirmed the crossover is ok.

This led me thinking "walpurgis" was...

Ok, thanks.

Yes, bad driver I meant there.

Ok, will take the crossover to a mate and check things out with a meter. Thanks.
