my silver one is on order now, they will ship this thing in a few weeks, after roon certification.

 

as an advantage, I promise myself a better sound by using a I2S connection to my Metrum Acoustis Adagio DAC, which gets a I2S Card from Metrum.

tom

 

I have ordered a black one. Will use i2s to my Onyx.

Just saw this mentioned in Roon forum, hopefully its more flexible than just Roon. AC powered so no PS tweaking possible

No PS tweaking is needed. It has a toroid supply. Metrum know what they are doing.

Looks like an interesting unit. If you are a Roon subscriber and a Metrum DAC owner, it may be a no brainer, especially with the I2S connection. For owners of other DACs, a bit less so, as no USB or ultra high rates and DSD.

 

BTW, it is available for pre-order (awaiting Roon certification): https://metrumacoustics.com/product/ambre-by-metrum-acoustics/

 

995 Euro seems like a very competitive price for an audiophile streamer with a good PS.

In the FWIW column I'm tinkering now with an Allo USBridge. It's pretty sensitive to PS quality and has some trade offs with iPhone as Roon renderer. The iPhone

has better decay time behavior on note playback but tends to mutter on background details. With good PS and ISO REGEN the USBridge is articulate, resolving 

but notes seem to fade prematurely. One of the things I really appreciated about the microRendu was its combination of resolution and correct decay behavior

for notes.

Metrum is shipping their Ambre Streamer now. End of the week it should be here.

It has to be good, cause my Aries is sold ;-)

Got my Ambre yesterday and it was the right choice. :-)

 

In combination with I2S data transfer to my Metrum DAC it does sound much better than my Aries with HydraZ reclocker before. More than i could imagine.

Bye Bye USB ;-)

Nice! I got the I2S module for my Onyx as well. Really looking forward to listening to it next week.

 

Have you any idea what DSP settings are needed in Roon for that configuration? I have no idea what max sample rate for I2S is into the Onyx.

I'm keeping the Aries Mini in my headphone station for now. Super performance from such a little box.

Hi George,

 

nice little blackbox :)

 

in the Ambre configuration it is limited to 192Khz. My Metrum R2R DAC can play 192Khz maximum too, so that is ok

Higher bitrates or DSD Files are downsampled in my chain.

I tried upsampling in roon, for example 44Khz to 192, but at the end i hear now without any dsp enabled.

So the NOS Dac with analog dsp-less active speakers makes the most sense (and sound :) ) to me.

 

regards

tom

Thank you Tom!

 

Pre-Ambre I have listened to CD sourced compression free FLAC files into my Onyx via Digital Coax and an Allo DigiOne Roon EP, so have just left DSP switched off. I know USB sample rate limit is higher, 384KHz I think? I didn't know whether I2S would be higher or not.

 

Regardless, I'll leave DSP switched off; there's something very pure about listening to the file without any 'tom-foolery'.

 

Many Thanks!

to be too tom-foolish is a problem, i do know good :D

 

so the Ambre has to be the serious guy in the house (without DSP)

Looking to start a discussion on what folks use/prefer for their Roon Endpoints. I'm floored by how good an iPhone6 sounds as a Roon endpoint feeding asynch USB, wondering what others have tried,

compared?

 

Hi,

 

I didn't read all the thread's pages but, due to the first three, where you were speaking about how good is iPhone as Roon endpoint, I just build my new chain with iPhone as Roon endpoint and Chord Mojo as DAC.

 

Now, my only issue is to make iPhone to play DSD through Roon to the Mojo (this is compatible with DSD).

 

Roon naturally see the iPhone/iPad that doesn't support DSD and it doesn't see that the Mojo is attached to it.

I know that convert DSD to PCM works because that's how I'm setup with the Eitr. However if you go under audio in Roon and select  device setup next to iPhone (the little gears symbol) you can get to all settings for DSD. If native DSD isn't working with iPhone, the Mojo manual says it supports DOP 1.0, you could try selecting that in Roon DSD setup, probably should also select that Mojo DAC is limited to DSD128 per the manual?

Regards,

Dave

It simply works. The only limit is that iPhone is limited to 24bit while Mojo supports 32bit.

 

Thank you.

George et al.,

I've been really enjoying my Onyx fed with redbook rips (uncompressed FLAC) via SOtM SMS-200 and Regen, windows Roon core. I am seriously considering replacing the SOtM/regen combo with an Ambre and I2S, and wondered if anyone has been able to tease apart the relative benefits of I2S versus USB and Ambre versus other renderers. Assuming that combo sounds better, in your opinion what is the main contributing factor, eliminating USB or swapping in the Ambre? Thanks!

Just for curiosity, there is someone else apart me, that use iPhone as main Roon endpoint? iPhone replaced the previous endpoint (laptop).

 

So actually I use iPhone either for the main rig speakers and for the headphones.

Just curious, have you compared it to iPhone or other more specialized Endpoints such as Rendu or SMS-200? Some people swear by its great sound if it is powered by LPS-1.

I only had a laptop as endpoint and now the iPhone.

 

After trying the iPhone I removed the laptop from the main speakers rig room.

Sorry Ron, just saw this.

 

I haven't tried the Ambre I2S connection yet. I have a reference Digital Coax cable, so I use that rather than USB or anything else. I will try I2S at some point, but USB doesn't do it for me.
