80's integrated or today's?

A question for those who are tech oriented and have knowledge of current amps and receivers...

What kind of power supply is being used these days? Is it the same type of linear power supply used in the 70's and 80's?

Or does the newer gear use switching power supplies?
 
Also remember that vintage amps are rated in watts RMS (root mean square) while modern amps are rated any which way, often peak output. Big difference....

Modern is very likely to be Class D as well -- digital. May or may not sound better, and 0.2% THD is pretty rotten, I think my 1980 KA-80 was rated at 0.02% THD 20Hz to 20kHz (and is linear far beyond that range).

Class D does not mean digital.

Prior to the FTC rules in 1974, "vintage" amplifiers were also rated "any which way".

Many modern amplifiers are rated using RMS power calculations.

All of these modern 100 wpc receivers sound anemic compared to a 30 wpc H/K amp from the 80's.
I own 3 current 100 wpc stereo receivers by Sony, Yamaha and (Best Buy) Insignia. My 80's H/K gear
at lower wattage ratings stomps all over them.

Yes, I agree that some mid-grade gear from the 80s is better than some modern AVRs.
 
The trouble is - here in the UK at least - there is a lot of absolute rubbish being sold on the likes of eBay for ridiculously inflated prices in the name of "vintage". Low-end Technics/JVC/Marantz integrated amps from big-box store stack systems, for example, invariably alongside speakers with plastic baffles, hard-wired cables, and drivers with shiny chrome-effect dust caps. These are no match for modern budget equipment. It was crap in the 80s and it is crap now. And this stuff is generally what floods the market.

If someone I know asks me to help them build a budget-priced system, vintage stuff probably wouldn't cross my mind.

There are of course some wonderful bits of kit available from the 80s and it's my favourite era :cool:, but you have to be prepared to pay what might feel like over the odds for it. It's a heart over head purchase which is fine for folk like us.

Mind you my Sony 530ES only cost me £120 and, well, we all know how good Sony's ES stuff is. It's my pride and joy and you'll have to prise it from my dead hands.

It doesn't help that you jammy sods over in the States seem to have readily available supplies of high end vintage stuff for about $0.005 from thrift stores and the likes. All we get is the cast-off black plastic crap with spring clip speaker terminals :(

Mind you, our car boot sales (known as flea markets over there) are often a good place for a bargain. I picked up a mid-range Sony CD player from the late 90s for £8 just this weekend :)
 
In terms of build quality and sound potential the older stuff can be a lot better. The main draw-back is that you may have to do some work to bring them back to spec.

Can be.

So it might or it might not. People should listen to what they buy and decide for themselves. IMO much of the old mass market solid state gear popular on AK sounded only so-so when it was new, much less now.
 
System is Computer mobo optical out, Dac to (amp) and then out to a HK 10" powered sub and the Paradigms.
Mainly for gaming and playing youtube/mp3's.

Based on your intended usage, anything more than this and you're wasting your money:

If you want louder explosions from your video games, maybe one of these:

Although your powered sub should handle most of the explosive game effects.

Both available from parts-express.com.
 
Jammy sods? Well....I have been called worse...I think :biggrin:. Have no idea what that means...

Don't worry @hcanning , the days of easy thrift store scores are long past. Sure, you might see someone get lucky occasionally. But 99.9% of that low hanging fruit has been grabbed up. I know because I frequent several thrift stores (Goodwill) in my area and even BPC is rarely seen these days, other than VCRs or the occasional multi-disc CDP.

You do make a good point about junk pieces from the 80's being offered up as "vintage" on ebay.
 
The only advantages of new equipment in general, are features and connections. You know, built-in DAC, ethernet, toslink, wifi and that sort of thing.

I don't think any of the "mass market" gear from the 80's is better than a modern, high-end integrated amp (for example, a Parasound Halo or Musical Fidelity M5si or M6si). I own a Halo and used to own an A5, and also own some very good "vintage" integrated amps from mass-market manufacturers (Sansui AU-919 and AU-7900, Yamaha A1000, Optonica SM4545 and SM4646).
 
A lot of the vintage gear we all have is upper end -- my little KA-80 amp wasn't a monster back in the day, pretty mid level at 48 W/channel, and it wasn't cheap. I got it from Wisconsin Discount Stereo for $189 in 1982 at about half retail or less. At least $600 now, probably more, it's not really fair to compare modern equipment to vintage un-restored equipment at the Good Will or thrift shop (or yard sales) at the same price point. It's not unusual to find Grandpa's stereo at an estate sale for a pittance.

There was plenty of low priced stuff around in those days too, I have some of it out in the garage. Doesn't compare to modern top end stuff, nor to high end vintage.
 
All of my older amps, except the British Fidelity A100 on the bench now, have been fully restored.

IMO, you should not expect much for ≤ $150 new gear. That doesn't buy much more than the box. Double the budget+ for new or spend a lot of time looking at garage, estate sales.
Or maybe take a risk, become an AK Subscriber ($25/year) place a Bartertown want to buy ad. If someone local to you has something that would please you.

Now I notice, it's for gaming and UTube mp3s. A chip amp might do. No experience with them, myself.

A little late to the discussion but computer amps are going to be on a lot, most of the time idling away. This calls for newer amp. I am running a 2001 Yamaha RX-777 stereo receiver which has 100 wpc. It runs cool to the touch because of the dual extruded aluminum heat sinks. Best part is it is dirt cheap.

. 2 %. is about 54 db down. Yes its true is hard for the untrained ear to reach into the signal and and hear distortion more than 20 db down. But there are other distortions there also that the .2 % only eludes to that you can hear. Harmonic distortion is only a clue to what else is going on. IM distortions, TIM distortions etc etc etc. And lets face it unless your speakers have been top of the line in the past 30 years ago or above average recently the speakers distortions would be significantly higher. Remember distortions emphasizing odd harmonics are much more irritable than more euphonic even order distortions.
 
Depends on your diy skills, you may need to do some work (clean switches etc...) on the vintage unit.
Rather than getting an entry level new amp, I'd opt to get a mid range vintage amp, maybe sansui AU505/555, Kenwood KA-5700
or 7100, Yamaha CA-800, plenty others from Pionerr and Marantz and...
I agree and once you get it working right, it will be the last amp that you will need to buy.

I would suggest you look at the 1 and 2 star reviews on Amazon.com for the R-S202 and make your own decision.
Receivers or integrated amps from the 70s,80s and early 90s are hard to beat for performance !

Or he could look at all the four and five star reviews instead. Many more of those ratings to read than the lower ones.
 
Will your friend allow you to audition that Pioneer SA-1040 at home? Because that integrated looks to be plenty good for what you want to do. Is the price right as well? I would obviously make sure that everything works on it.
