How good are recievers these days?

Hi Folks. I haven't been on here in years. I sort of fell out of the high end audio about 8-9 years ago. Need some advice

So long story short, i have a set of Magnepan MMGw's i use as my mains which replaced a damaged paif of Jmlab Chorus.. I had a Denon 3805 and planned to pick up an outboard amplifier to drive the speakers. A friend loaned me an amp which had serious issues and killed my Denon 3805, so my amp budget got raided to replace it with a used Denon 3806.

As it stands now, it does not sound horrible, but i now have a small budget for an amplifer. between 500-1000 and i had planned on getting something used.

I ran into an old friend when i was picking up a 4k LED TV this weekend who worked at Best Buy (i can already hear your eyes rolling) at thier magnolia center. He mentioned they did multimillion dollar installations, full high end audio, etc. Today i asked him if he had any recommendations for a good 2 channel amp that can handle a 4 ohm load.

His response suprised me, he recommended a Pioneer Elite SC-81 receiver.

He does this stuff for a living, I have been out of the audio hobby and not been paying attention for the better part of the last 10 years. This receiver sports the D3 digital amp, and it claims to be stable with a 4 ohm load.

How good are these digital amps? I remember Velodyne putting digital amps in thier subwoofers a long time ago, but i know nothing else about them. Can that actually push the Magnepan MMGw? or should i go back to looking at a second hand Parasound or even some Adcoms?

Thank you in advance!

I don't get all the hate for class-d amps. I wonder if there were such feelings when SS first came out.

If you only want a dedicated 2 channel system, get the Classe. However, if you want a multichannel system with decoding of the digital audio formats, like Dolby HD and such, get the Pioneer. Several of the Pioneer models have pre-amp out. If you don't like the sound of the Class-D amps Pioneer supplies you can always get an aftermarket amp in the future.

Class-D amps are more expensive to produce the AB amps. The mid-fi companies are either producing them to waste money, marketing, or they believe they are better.

Meridian uses class-d, as does Mark Levinson, b&o, Classe, Burmester, MBL, Bryston, Audio Research and others. I don't think any of those companies are real slouches and would put out a bad product and risk their name.

forum post: "...Another Onkyo bits the dust......?

short answer: bad in many cases - ultra-cheap build quality and short life

Check out he canuckaudiomart posts about the repeated failing ONKYO gear with an average life of less than a year before failure.

edited post takeaway:

"...Bought a new NR818 at Best Buy in April, to replace it.
I know, sucker for punishment.
But, I like them when they work and the menus and setup are awesome and for the money they are great............If they last.

This $1000 piece of crap lasted 6 months before the same issue, no hdmi out.I will take it back to BB and demand a refund, if not, the expected repair cycle is 4-6 months.
If I get the POS back I will sell it....

....If you have one that lasted past the warranty, magic.....I will never buy another Onkyo....

....Want one to last just buy an older one without that $hit HDMI garbage.IMO it is the major cause of receivers failures and don't just think its an onkyo thing, its all of the current crap out now.
....

But this is commonplace with most receiver brands under a certain price level. You just don't get decent build quality or discrete circuitry and power under around the $1700 level. Facts of life with receivers

A new just-posted new 3rd party comment today on the current CAM forum blog re: ONKYO receiver failure.

This guy is allegedly a tech: his edited extract from that post:

"....IMO, stick with separates, even for the switching. Screw convenience, it'll eventually stab you. Always a price to pay, especially when it's a cluster bomb of all in one, like a VCR/DVD/TV. VCR lasts one year, DVD maybe two...and the integrated TV for another 15.

As a guy who sometimes services those all inclusive monstrosities, I'll tell you, I'll never buy or use one. All compromise, for the sake of convenience. From $400, to over $4000, all the same. I've never seen (heard) one make it past a mid-fi sound, no matter the price...."

Re:Clutter. I still wonder, "If you do not have phono equalization and moving coil signal boost, what are all those preamp components doing in big preamps, since the incoming signal doesn't really need improving?" Attenuation, yes, but do active components participate in that?
