Yamaha AS701 MK2….

[Hifi for life .]

As some you know , I am extremely excited for the upcoming Wiim Amp Ultra.

AirPlay 2 is no big deal … But can I connect the N132 to the Wiim Ultra Amp optical? Would I need the Ultra streamer for this application?

This way I could get AirPlay 2…

Should the Ultra Amp not be too my liking. I know some loathe it-some love it.

I’ll return the Ultra to the shop…

Can one mini DSP be connected to the AS701MK2? One with the ability to run 2 stereo subs .

Can one mini DSP be connected to the N132 streamer from Bluesound?

And isn’t the N132 sub bass management designed for active speakers ? Even with Dirac .

I know Dirac can help with the main speakers, with the amp the N132 is connected to.

Thanks .

What's MKII? With mini DSP Flex (or any other with 4 analog output chenels or more) for example you chose which kind of analog outputs you want (need) balanced/unbalanced of course you fead it trough it's inputs and still choose digital ones when you can. For home it's unbalanced and so is with Yamaha (only really high end A-S 2xxx series have balanced inputs) and of course to sub's with unbalanced inputs. Flex has 10x PEQ bank per each chenel on both ends (input and output ones) from inputs you clone how you wish and then do passes and EQ on cloned ones. You save PEQ's on input one's for general EQ and shaving filters for purposes such as ELC which you still tune by hand. Dirac Live doesn't have multi sub suport and full flagged Dirac (full, multi sub) is not available as a license and license for rare top line AVR's with suport for it costs as MiniDSP Flex.
For WiiM amp and other WiiM's as long as it has a input that fits in it will work but ADC section is best to say not great so there you are even more encouraged to use digital when posible. I still don't get why would you plug an old streamer to a new one nor I care about it self low filter as you will have more than enough PEQ's with something like MiniDSP. I am one of those who like it all, unrestricted and unlimited in the end to mix it as I like so I use PC for DSP processing. For stuff as temperal FIR's to separate PEQ and FIR at the same time and mixing all back down to convolution FIR when done. And bunch of tools including effects, emulation, phase manipulation and so on.
I guess you already have Yamaha and it's fine amplifier I settled down with older A-S700 (for old electro mechanic input stage).
To learn it will take some beating but you will learn eventually. Really not that hard for basics and if you get madly into it not hard regardless. All it needs is some time and practice.

Sorry , should have explained it better .

It appears it is new mK2 version . Google and you’ll see some different layout inside of the amplifier…

On the amp and box it says AS701. So why it’s called “MK2». Only the store-Yamaha knowns…

With mini DSP Flex…

I am bit rusty ! English is not my native language.

Can you please recommend one Minidsp which suits my needs? For the Yamaha.

2 stereo sub outputs or 4. And how exactly I would connect it to the amp. Can it be connected to N132 streamer ?

I am asking if the Node N132 can be connected directly to Ultra Amp digital connection. For AirPlay 2. It’s no big deal .

Just asking…

Thanks for input .

It is unclear what your needs are, what you currently have and what you are considering buying.

Yes, the Bluesound Node has optical out and Wiim Amp Ultra has optical in so this should work fine. Optical (toslink) as specified is limited to 48 kHz at 20 bits PCM so you won't get the full resolution that the Node is capable of. It is also unclear to me what you would gain from inserting the Wiim between the Node and the Yamaha. These devices overlap quite a bit in functionality.

 

[ZolaIII]

MiniDSP Flex 2X4 unbalanced for mains + up to two sub chenels (500$) up to Flex THx 8x8 both balanced and unbalanced for what you make of it (1000$). Preferably you take Toslink cable and stick it from Node output to Mini, WiiM, Yamaha and so on.

 

[ZolaIII]

Such a thing like A-S700 MKII dosent exist. Analog unbalanced input is rated at 99 dB SNR and integrated DAC is not so good old rebtanded low end BurrBrown in Texas instruments brand. Still more than good enough regarding analog inputs to amplifier stages as measurements show but far cry of old one electro mechanical ones up to 110 dB SNR (just saying).

Then we’ll try the Ultra Amp first. Like it’s designed for.

Should it not to be to my liking (thin sound). I might hunt for Minidsp . In the meantime I’ll set the Yamaha to fixed volume setting , then use the Ultra streame for bass management.

The problem I’ve got,is no store we’ll borrow me a sub. I am not then going to be able to test the Ultra amp with sub first
My system is the Dynaudio’s Evoke 20.

N132 which measures poorly ! And a few times week it struggles to find Spotify connect .

Oubez connect works !

BluOs support is hopelessly lacking. Back in day I had to return 4 Nodes, because each one had network issues .

“It’s your net work “. Then suddenly new firmware update fixed it .

I am pretty sure I’ve got some bass nulls , because I need to adjust the bass till around 2 o clock . Not sure this would matter. Since it is best tone controls I’ve used. Yamaha sure does deliver on tone controls.

Sub would be low pass . Real shame by Yamaha engineers to not put in a real bass management. Like the old N803. I believe it was called .

I know many prefer high pass-some do not. I guess it would then depend on the speaker design.

Back in day in another listing room. I owned the Marantz PM7200 with SA1550. The bass was insane ! I was lucky with the setup then !

Sorry , for editing my post …

 

[rolfrander]

For bass you should get a microphone and a computer running REW, and experiment with placement. Then you can compensate with EQ on the Wiim. A mini dsp has more flexibility, but it would also add more complexity.

 

[Hifi for life .]

The ultimate solution would be the C399, which I believe measures pretty decent.

Darn to expensive.

Dirac onboard and BluOs. BluOs software is better than it was. But if it’s the same like my N132 streamer …

REW and the Umik-1 is nice idea.

I guess any simple cheap laptop with enough RAM would do the job ?

MiniDSP Flex 2x4 could be what I need.

What exactly does DSP device do ?

As i understand; it cannot solve bass nulls.

Only peaks. I am rusty, no glue what peaks are .

 

[ZolaIII]

I wouldn't call self filters as proper full menagement but just one filter similar to pass filters with that said you have only more PEQ to understand the basic set you will need with speakers (for headphones there is also angle filter which is explanatory by it self horizontal). Along with Q scaling and a little bit of math to it (for crossover and all shaving filters to 1 and aiming and PEQ targeting to 50).

Sorry to hijack my own thread …

I’ve got pair of Mogami 3103-not because it sounds better !

I’ve gone done the cable road. It’s just dealer magic card trick .

I plan to add some better banana plugs, because then ones I’ve got are not so snug any more. Hicon plug is what I’ve use .

I intend on adding bit more split difference between left and right wire. I would need some kind of stress relief heat shrink.

Would Amazon 3.1 ratio do the trick ?

Yes, DSP for new beginner is not an easy task. I’ve read it takes 3-5 months to proper get the hang of REW.

I’m logging off .

Thanks everyone.

Your experience regarding DSP is amazing.

Depends if you want to do it all on PC in unbalanced flavor up to 6~8 chenels you are better of with proper desktop PC (brick) and PCI-E audio card. Even old laptop with deacent output is good enough for REW trough USB to receiving multichannel DAC or trough external USB to coaxial/optical RCA or Toslink and from there to such.
Microphone obviously enables you to see what neads to be done. DSP ain't magic stick but it is next best thing to it. Main purpose is to counter Xbox of the room or better say room fundamental. Without it to aim and adjust speakers along with accustic treatment so that you don't get nulls and then to iron out rest of the peaks to a shoulder frequency or beyond it to what PEQ Q can aim or FIR above it.

No it doesn't, download @Keith_W publication (tied to his profile) and start reading immediately.

The Ultra Amp arrived today.

Sounds amazing, and tons of power.

No speaker hiss also ! Quite like a mouse.
No noise from the device it self (at least I hope so.)

I’ve added my own DSP settings. Punchy-deep bass.

Few questions…

It gets extremely hot ! Putting your hand on the device and you’ll notice it is very-very warm to touch. Is this normal ?

The volume dial on front of device has a certain noise. Like scratching. Is this normal too ?

Plus’s when it was 1 hour old , it had some pops and clicks while switching sources.

Normal …?

It also had some strange HDIM issues too. Picture but it said “no connection. It has gotten better with time .
