Metrum Acoustics Octave - Page 33

post #481 of 666

It's going to be either the Stealth, or even cables. The Octave Mk2 by itself sounds very lush and smooth.

Also, I didn't hear any special differences after the first hours of burn in.

In turn, even changing analogue interconnects has a very audible effect in my system.

The room we tested the MKII in is definitely ideal and has very good acoustics. Prior to the 8s, he had the Pro 6s and they synergised exceptionally with his system. Neither speaker we've ever thought to be bright. Yes they are monitors designed for a flat response, but compared to some electrostatic Quads, they are the opposite of harsh/bright... The Antipodes are stunning as interconnects compared with  Audience and other high-end cables..

Anyways, we also tested it on LCD3s, k701s, HD650s via Cavalli Liquid Fire (ALPS RK50), but still the ear fatigue was ever present.
Has anyone here heard equipment like the Twisted Pear Audio Buffalo DACIII, Lampizator Lvl. 3 or other great value dacs?
Do owners of the Octave agree that it punches in way above its pricepoint? Any suggestions of other dacs that you've loved would be greatly appreciated

Quad electrostatics harsh/bright!!

My god these are some of the most natural sounding speakers ever designed if properly placed in the listening room.

A mid range to die for and superb natural extended treble.

I am really sensitive to hot treble but if I could only have one set of speakers if would be a pair of classic Quad ELS.

Metrum Octave is very special beautifully sounding DAC, NOS shows up very well as you dive in musical listen. I bought this a month ago and could not be happier. Octave has amazing ability to produce natural sound and singer voices sound so emotional that i did not hear from many more expensive DAP, i mean voices sound damn live like, it scares my Naim cdx2 in this. music has organic feel and flavour, there is no mess and no artifacts, nothing forced onto music. very much agree this is like drinking water from natural spring, amazing product unique in its own. Matrum makes my Ayon amp and Sonus Fabers Cremona sing effortlessly magical.

Really Cees, the owner and creator of Metrum, has golden ears and knows what music is all about.

This pretty much reflects my own impressions of the Metrum Octave Mk 2 that I've had for a couple weeks. It's got me wondering just how much better the Hex might be. I've found the Octave to be quite sensitive to the choice of interconnects on the output.

 

I hope to be able to compare the Octave to the Chord QuteHD/MX QX soon.

Charnwood, lucky you :-)

I decided to stop on Octave since Hex cost is something i want to postpone for now :-(

That said never digital music sounded so realistic, especially vocals, i feel like being connected to the singer. i heard many good DACs and CDPs but none i auditioned could produce such naturalness to voice, not even my Naim which sounds amazing and beats Metrum in dynamic, not even Naim can reach this clarity level, this is why i love NOS and love Metrum.

Has there been any wild guess about the DAC chips they use yet? I'm sure some diyaudio nerds could find out?

post #488 of 666

Does anyone have an retailer in the NE,where I can audition the MKII,or,even a used MKI

There is a seller up in Boston,but he is out of stock?

Anyone?

 

Tnx

Mike

Best wild guess so far is DAC8580 from TI - http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=dac8580&fileType=pdf

Nope.

 

The Octave does not use any of the conventional DAC chips found in most consumer DAC's, such as TI's Burr-Brown, Wolfson, Sabre, AKM, etc. Cees Ruijtenberg of Metrum Acoustics is a guy who originally researched and developed electrostatic transducers, marine acoustics, sonar and radar technology. From his long experience in these fields, he developed a proprietary DAC chip of his own that is exclusively used in Metrum Acoustics DAC's. So basically speaking, his DAC chips are unique.

Ah, that would match it indeed beerchug.gif

 

I see that OS can be disabled, and I only read that dutch company claiming to use industrial type DAC chips...got link? I don't see how a small company could come up with the costs of building its own DAC IC, let alone would bother hiding the model number. They'd just write their name on it at the factory.

Its true that this DAC chip isn't a conventional audio DAC, but it most certainly fits the pinout used in the original Octave (I haven't checked with the most recent incarnation). The notion that Cees developed a proprietary DAC is quite simply laughable. If he'd done that he most certainly wouldn't waste his time scratching off the markings of his own chips now would he? He'd be jolly proud to flaunt his proprietary nous.

 

Incidentally those who are a tad curious as to why Cees' DAC sounds better than a lot of DACs that are using other off-the-shelf chips, then have a peek at this tech note from TI about glitching. Note that the type of DAC used in the Metrum is a string DAC, not R2R which is more commonly used in audio multibit devices (PCM1704 being a notable example).

i am not sure if i understood a word here. and i could not care less about what is inside Metrum DAC as long as it sounds great to my ears. i am not tech savvy person but a music lover. should i need to know more about inner parts i will call Cees.

That's a 16 bit device and yet the Metrum is 24bit capable.confused.gif

i do not know ... you can always write to Cees from Metrum and i am sure he will respond to your question (if asked politely).

 

all i know is i love Metrum sound and could not care less for what is inside tongue.gif
