2 channel Receiver that passes 4K?

So which manufacturer has a two channel stereo receiver that passes 4K? Looking at Denon and Marantz websites yield multi channel, not two channel. I'm sure I'm missing someone out there....


Thanks for the info!

Integra has a DTM-7 that I think is only like $500 that will do that.

If you want to blow a bundle the Lyngdorf tdai-2170, with hdmi module. Nad is working on a 4K module that will be used with the NAD c368, c388, and M32 Masters.

I wish here were more. I like having room correction and none of these offer room correction except Lyngdorf, so I bought the Anthem MRX 520 5 channel avr. Bare bones compared to most AVRs which is what I want. It's almost like having an integrated with room correction, hdmi and a tuner with 3 extra amp channels. I only do 2.0 and the anthem was the closest thing to checking all my boxes.

Thanks all, you gave me some GREAT options. seriously, all I need is two channel output with 4k ability. The onkyo and Pioneer are probably my choices.

Do you intend to run a sub with it at some stage? If so, there's no bass management capability on those few 2 channel receivers.*** A summed full range copy of the main channels is simply routed to the sub out jack and you're expected to LPF it at the sub. There's no simple way to HPF the mains, which defeats half the purpose of running a sub; hiving off high excursion low bass.

The digital bass management provided by even the most entry-level 5.1 AVR is worth the trade-off of a few idle amp channels, IMO. The Marantz NR ("Slimline") series are a good option because you're only paying for modest amps and they have main channel pre-outs, if a power amp really is warranted.

Edit: *** The Onkyo TX-8720 and Integra DTM-7 do in fact have basic management capability; that is, to redirect bass from the main channels. Neither unit appears to have Dolby Digital or DTS decoders, so an LFE channel cannot be processed.

The pioneer seems to be low power compared to the Onkyo. Giegar has a point, if you ever want a sub an AVR with room correction will do a much better job of blending the sub with the mains. As I said, when balancing all my options I opted for a simple 5.1 receiver from Anthem as opposed to the other options.

I'm pretty sure the Onkyo does have bass management, it has dedicated sub outs and I saw this in the manual [page 37]:

So it's obviously not as advanced as real room correction but the basics are there

Thanks mate, good catch! I appreciate the correction. I'll go back and edit my post.

This capability makes the Onkyo TX-8270 and stablemate Integra DTM-7 (linked earlier) a couple of very good options for OP @Killer .

Onkyo TX-8270: $450 open box or $400 factory refurbished (currently sold out).

I've been looking at the 8270 myself, it seems like a good amp but it's Onkyo and it's HDMI so I'm waiting for someone else to take the leap and suss out any switching/handshake issues.

Just an update: I bought the Integra DTM-7 and am super happy with it so far. I don't have my new TV yet so I haven't tested it with 4k content but it's working perfectly with my existing hardware [Tivo, PS4, Apple TV, Sony Blu-Ray player, Airplay audio from my computer]. It was a snap to set up and sounds great. I'll post more impressions once I get my new TV and 4K hardware connected. My only gripe would be with the remote, it's a little '90s feeling with the tiny identical buttons, etc. I wonder if a newer Onkyo replacement remote would work with it?

I got sick of receiver shopping between HDCP 2.2, Dolby Vision, handshaking issues, calibration types, sloppy user interfaces, half-assed CEC, bad remotes and BS power specs. I was running 3.1 before with no plans for rear or height channels, a lot of the speakers I was considering [and the ones I ended up with] were 4Ω and pretty much nothing under a grand can drive 3 channels at that impedance. It also helps that I got a deal on a refurb model and some clearance speakers for $200 less total than my original receiver budget alone.

I'll probably go back to at least 3.1 in a couple years once the HDR format wars are over, 4k handshaking is sorted and HDMI 2.1 is common. For now this works great and if I get an itch to try out some weird speakers I know it'll drive them. I'm enjoying the simplicity of the setup as well, after dealing with menus for years having Bass and Treble knobs on the front panel is almost refreshing.

Thanks for the update.

An Onkyo remote would probably work. You could also look into a universal remote to control all your devices. I got a Harmony Touch a several years ago (after our PVR's remote went on the blink) and it still does the job well with an Onkyo AVR and three sources.

Incredible...
The mentioned stereo receivers from Onkyo and Integra both lack a key component feature...
No Pre-Outs or Main-Ins.. Yet both models retail for >$500..
Before designing a new stereo receiver model these brands need to do some market research about desired market features & typical use cases...

Just my $0.02..

FWIW, I've never owned a receiver or processor that fit my needs exactly without also having features I never use. That's a pretty tall order IMO. Especially these days, I'm happy as a clam with my 5.2 setup, but try to find a processor that does ONLY 5.2 but also passes 4k HDR via HDCP 2.2, has balanced preouts, advanced room correction and multiple 12v triggers. Doesn't exist. Everything with those features is also set up to run many more speakers than I use. I buy it anyway and just don't run that many speakers.

Along those lines, I'll echo some other posters and say to the OP, just buy a multi channel receiver. If your speakers are bi-ampable, many multi channel receivers can accommodate that too, so you wont be letting so many amps sit idle. Or you can buy a receiver that has the ability to turn off the amps you don't need if you'd like, but having amps running with no speakers attached isn't an issue with modern designs.

I guarantee you they did a ton of market research and found that people who care about things like pre-outs are way upmarket from the $400-700 price points these list for. This thing deliberately had stereo pre outs excluded, it probably would have cost them maybe a dollar for the jacks and extra soldering. They could probably remove the amp entirely and stick XLRs on the back of the DTM-7/8270 platform and charge 2 grand for it, as long as it was branded something more exciting and had a sexier design. Separates shoppers are a whole different market for them than customers who buy $500 receivers.

It's a shame, really. If they had stereo pre outs this would be a killer product and would be a great way for analog folks to integrate HDMI and streaming into their systems. Don't be surprised if there's one next year with pre outs [plus a few other features] for $200-400 more.

Does the 8270 pass the LFE track to the sub out when receiving a surround signal. This test claims it does not:

https://www.lowbeats.de/test-onkyo-t...er-mit-hdmi/2/

"Einen kleinen Pferdefuß habe ich leider in Kombination mit Surround-Quellen gefunden. Selbst wenn man mit Subwoofer arbeitet, richtet sich Onkyo für den Stereo-Downmix streng nach Dolby-Vorschrift und lässt den Low-Frequency-Effects-Kanal (LFE, das „.1“) einfach weg. Schade, denn mit Subwoofer und auch dank genügend Power der Endstufen mit großen Lautsprechern wäre der hier angebracht. An dieser Stelle wird etwas Potenzial verschenkt."

My understanding is that it uses a 2.0 stereo mixdown for all surround signals which does not have an LFE channel but includes the full frequency signal. I watched Mad Max Fury Road this weekend and it gave my sub a workout, it's not like they just exclude the bass. Maybe if someone else gets one they could A/B it with a multichannel receiver running 2.1 to see if it's actually different.

edit: Some poking around seems to indicate that some early Dolby Digital decoders did just throw away the LFE channel during 2.0 mixdown but that's definitely not what this receiver does.

A key target market for this category of product is the user that wants HDMI, 4K video, DSP decoding but doesn't care about multi-channel amplifiers for surround. However 1 area, that typically needs upgrading is more stereo output power, adding Pre-Outs/Main-Ins cost <$2...

Just my $0.02...

IMO it would be nice if there was a Processor only (IE not a receiver) that would be a bit minimalist, IE 1x HDMI in, 1x HDMI out, support ARC (so the TV remote can control the volume) have an L and R out, and use very high quality DAC's (IE 32bit/384khz)

I know I'd be interested, as in my bed room I just added a MiniDSP 2x4HD that I'm going to use initially as just a crossover (to do 2.2), and eventually full room EQ, and it'd be nice if the sound source (Currently the L/R RCA's on the TV) were higher quality.

Another option for the higher end of the market [retails for $3600]: the Arcam SR250, there's reviews here and here.
