Are the 2 subwoofer outputs the same (internal splitter)?

Krell Evolution 707 Home Theater Processor

Will appreciate comments from those who used or listened to both models.
I have owned the Krell Evo 707 since its release. The Evolution 707 provides stunning audio performance for music and home theater. I use it with Krell Evolution amps wired with CAST. It is fast, crystal clear, life like, with terrific sound stage and imaging. Bass is also fast, tight and deep. For sound reproduction, there is nothing like it on the market. If you speak to the people at Krell, they will tell you the 707 is far superior to their current processors.
Krell 707 is HDMI 1.4. Krell will not upgrade it to HDMI 2.0 or 2.1. It will not accept 4K video. It is my understanding that Krell is working on an external device that will provide the Evolution 707 HDMI 2.0 (maybe 2.1 ?) capability, and it should be available within the next 60 days.
The 707 retailed for $30,000. If you buy the unit, make sure it is working properly. Krell had problems with HDMI handshake in their early units.
The pre-amp section of each channel in the 707 is closely based on the Krell Evolution 2 (ultra high end top of the line $40,000 pre-amp). Krell stopped making these ultra high end products because they are not profitable due to market changes.
I will never sell my Krell Evo 707; it is best the sound upgrade I have ever made to my music/home theater system; a rare, unique product.

That's quite an endorsement.

If you do need to step up to 4K etc have you considered getting an external HDMI switch and/or HDMI audio/video signal splitter?

Krell's COO told me they will be offering an external device that will provide 4K cabability within the next 60 days. I don't know if it will be HDMI 2.0 or 2.1. Using an HDMI splitter is an option, but it can degrade audio/video. I am hoping to use E-ARC when it becomes available. LG's OLED 2019 models are supposed to have HDMI 2.1 with E-ARC (Enhanced Audio Return Channel). Hopefully it will work with Krell's new external device.

"Degrading" is what's supposed to happen when 4k is converted to 2k. But otherwise both audio and video pass through untouched.

I'm using a Gofanco splitter/scaler so I can access UHD content and feed the audio + 2k video through my SSP-800's HDMI 1.4 while the 4k video goes to the PJ. If you only need to parse out the audio, Transformative Engineering makes a good unit.

But let us know what sort of solution Krell comes up with.

Thanks for the information. I was not aware of the Transformative Engineering HDS-12AVR. Are you using it? If Krell doesn't come up with a good solution, I will consider it.

I am not using the HDS-12AVR as I wanted video from both outputs. But we have used other TE units before and they design them and stand behind them.

I just received an email:

Good afternoon,

I hope all of you are well and enjoying the new year.

We have had many requests for an add on to the Foundation to support HDR and HDMI2.0b, hence, the Krell HDMI 4K HDR Switcher with specs shown below. It hooks into your RS 232 port via an adapter, supplied with the unit.





  • Full support for 4K 60Hz with HDR (HDMI 2.0b)
  • 4 HDMI inputs (3 when used in loop back configuration)
  • Single HDMI connection to TV in loop back configuration
  • HDMI video output for connection to TV
  • HDMI audio output for connection to the Foundation (original or 4K)
  • Seamless operation with the Foundation using the supplied USB to RS-232 adapter (the 4 HDMI inputs are mapped to HDMI inputs 1- 4 on the Foundation)
  • RS-232 control for stand-alone use with a home control system
We are determining build quantities, so please let us know if you’d be interested in purchasing this unit by clicking the button below to take a one question poll. Retail price is $999 US. Thank you!

The old Meridian HD621 and their new UHD722 do the same thing. One HDMI lead goes to the TV from the video out port and one to an input on the Foundation from the audio out port.


My Denon BD player has separate HDMI outputs for video and audio too.

Krell HDMI 4K HDR Switcher or Wait

I also got the email.

For me it boils down to how long until we see the Foundation replacement with HDR switching? If we have to wait long, then maybe Krell HDMI 4K HDR Switcher is worth it. If another processor is coming soon, then I would wait for that.

I read above that two new processors are in the works. Does anyone have any details?
Thx.

The price seems OK but I'm confused by the

I'd like it better if it were HDMI 2.1 and 8K capable.

And how does it work? Video to TV, ok. Audio to some input on the Foundation, sure. All 4 (or 3 in loopback) would then be a single device to the Foundation?

I think physically, yes, there will be one (audio) connection between the Switcher and the Foundation. Logically however, everything will remain the same as you have it now; each device will still have it's own video selection via the RS-232 connection on the Switcher and use a single audio connection for all four (or three) video inputs.

currently I am controlling the Foundation via the RS232 port: does the switcher use the same port?

Two New Krell Processors are still in design stages...

I just called Krell and they confirmed that two new processors are still in design stages and probably won't be ready until the end of this year or next year. That is why Krell released this Switcher now... Hope this helps.

It says: Seamless operation with the Foundation using the supplied USB to RS-232 adapter (the 4 HDMI inputs are mapped to HDMI inputs 1- 4 on the Foundation)

So I'm thinking this will be a RS-232 connection on the Switcher to mini-USB on the Foundation.

I would probably be interested if I had any 4K hardware or software as I like the idea of an offboard solution that can be used with different processors, but I don't have anything 4K.


Interesting that they say a software upgrade will add compatability with the 707. Great for owners of those.

Judging from that interest is pretty good. I responded other as I'd like HDMI 2.1 to support my planned LG C9 purchase.

I suspect Krell is holding off on HDMI 2.1 until their Foundation replacement processors arrive. But doesn't hurt to ask

I thought it was odd, too, when I first encountered it. I was driving two different screens (2k monitor and 4k PJ) depending on the occasion – no need to use the PJ all the time. The Oppo BDP-93’s dual HDMI outputs worked perfectly for that.

When upgrading to the dual output Oppo UDP-203 the monitor had a blank black picture.

It appears that it is easier and less expensive to output a blank 2K video signal than to jockey splitting a 4K source to two different displays. One only needs to look at the devices that do support dual 4k/2k outputs to see that. Check out the flexible splitter/scaler from HD Fury ($300). I'm using a $56 alternative from Gofanco. The 2K video carries the Atmos or whatever soundtrack the program uses. The downside is that either of these devices come with additional complexity for setting EDID compatibility, and that brings a degree of complexity and other handshake challenges that I'm sure Oppo and Krell want to avoid. The "blank video" option appears to sidestep all that nicely.

I hope I can post here as I don't see any forums around Krell Evo 707s pre/pros...

@matjet - I hear you! I too have the Krell Evo 7073D, and simply love it... I've had opportunities to trade out of it for a F4k or Lyngdorf MP50...simply couldn't let it go or justify the swap.

I noticed your post because, unfortunately, I have the HDMI audio/video synch issue you mentioned that the early 707's are known for. Currently, connecting an HDMI audio input, I now get 'waiting for audio' on the screen, so no sound. Can I assume it does detect the HDMI connection because the screen notes the resolution and refresh rate the signal is that...1080i @ 60Hz.
It just can't decode & play back any sound.

Is that something that needs to be sent back to Krell? Factory resetting the unit doesn't fix the issue.

Any feedback/help on my 'waiting for audio' HDMI issue would be very much appreciated; until it gets fixed...I remain a very sad duck

The downside is that either of these devices come with additional complexity for setting EDID compatibility, and that brings a degree of complexity and other handshake challenges that I'm sure Oppo and Krell want to avoid. The "blank video" option appears to sidestep all that nicely.
Not too long ago I tried the HDFURy Integral 2 (same as the Vertex, but without the screen)...my 707 wouldn't decode any sound for the life of it, but my TV happily displayed whatever video codec/resolution/format I threw @ it. Still not sure why that didn't work...on paper, the HDFury Vertex/Integral 2 would be exactly what most of us with legacy pre/pros would need to properly decode/pass through Dolby Atmos audio codecs and DV/HDR video signals.

I got same email from Krell back in Jan and I voted YES - I want one! So I'm really hoping that Krell would come up with this switcher that will work for Foundation, Foundation 4K and Evo 7073D!!

I may be wrong, but I think this solution would be perfect for most us with Krells that have HDMI 1.4 only (would work great for any Foundation pre/pro). I'm in the camp of 'the less equipment in the chain, the better', and I wouldn't use the processor to pass thru any video. Just let it handle audio by utilizing 2 separate HDMI cables:

1. Send the 4k video to TV
2. Send HDMI audio only to one of your HDMI inputs of your Krell (I guess this cable would have 720P video muted to comply with copy-write HDCP laws)

This is exactly how the Oppo 203/205 does it currently via its dual HDMI ports. So in my case, that would work perfectly as I have an Apple TV 4k streaming device: feed it as input source to the HDMI switch/audio extractor and connect my TV panel and Krell 707 separately as above.

The only question I have: would this switch ALSO pass through Low Latency Dolby Vision (60Hz) or just DV @30Hz and HDR @30/60Hz frame rates? I have a Sony TV that features Low Latency DV...

Question

Hi All,

New Foundation 4k owner here. Got a great deal from an authorized dealer, but I'm having trouble updating the firmware.
It's on v1.33 Feb 26 2015.

When I go to update it seems to be very successful with updating this - success - and updating that - success - and lots of downloading percentages clocking along but in the end it sticks on webpages.bin 100%. I've tried three times now and let it sit on webpages.bin 100% for up to an hour, but no real update.

Is there anything I'm supposed to do?
Does anyone have or know where I can get the files to try updating from a usb drive?

I've written my dealer and will call Krell on Monday, but thought I'd check here just in case.

TIA

That used to happen to me with my non-4K Foundation. USB update was the only solution.

Ah. Is there a place to get the files or do I have to wait for Support during biz hours?
