Metrum Acoustics Octave - Page 34

post #496 of 614

Yes that's what Cees has said..... but no known 24bit DACs in that package and the Martin Colloms review didn't show anything close to 24bit performance from what I recall.

It was my understanding that the Octave is R2R. Am I missing something here?

I believe you are - its a string DAC and the lower glitch compared to R2R is one of the key reasons why it sounds so good.

 

If you need more convincing, pull up MC's review and ask yourself if any known R2R DAC has such poor THD?

i have Rega since long ago, i had Mytek for some weeks, Young, now have Metrum... of all them Metrum is the best to my ears.

 

Rega, Mytek are 24bit capable, Young is 32bit capable tongue.gif

24bits in my estimation is just marketing specmanship - don't worry yourself about it. 32bits is a total joke.blink.gif

mastertapes ?

post #502 of 614

Of course the professionals need to work with more than 16bits but here I'm talking about consumer DACs.

Sapien, good hires recordings are made from mastertapes. many DACs are 24bit capable. i do not know how you come to your conclusion.

post #504 of 614

24bit means 6*24=144dB, there are no real 24bit DAC chips on the market....let alone optionally NOS.

 

16bit means 96dB of headroom, more than enough to become deaf with headphones =)

leeperry has understood. '24bit capable' is just marketing as I said. How do you come to your conclusion that any recording is true 24bit ? By 24bits I mean with noise below -140dB?

i am not tech savvy so i trust what i am being told or hearing wink.gif

whatever we talk Metrum Octave is a great sounding product for me personally and this is not overly pricey.

Yeah not only are there no recordings with enough dynamic range to warrant 24 bits, but Im pretty sure the list of dacs capable of resolving 24 bits is pretty small...

i do not know if 24 bit or not but my Metrum sounds perfect for every bit... and vola i added Audopilleo 2 with Pure Power (AP and PP respectively) which brings amazing clarity and refinement to Metrum lifting this combo on a whole new level. i choose option 2 for connecting AP and PP with two USB cables out of Mac, one into AP and another into PP.

 

sonically Audiophilleo opened up the whole spectrum, bass dynamic and articulation become insanely clean so i can hear every drum palpation, trebles get more air and more sophistication ... but the best part of the story are vocals, singer voices never sounded so life-like realistic... i can feel singer entering my room and singing just for me, this gives me great sensations.

 

funny is i did not expect AP to bring such a refinement to Metrum so now i am a believer. advice and service from Audiophilleo's Philip is top notch, i am so thankful to him for giving me good advice and his patience in explaining things, it was really great experience in all directions.

 

guys, if you want USB to SPDIF adapter i can only say Audiophilleo is the way to go. it will bring a breath of fresh air into your music and will make your system sound like never before.

 

love these cute two little boxes i got from Audiophilleo. ahh..... yes..... i got AP2 unit in black and PP in gold....... GoooooLD........... but not for Gold Member tongue.gif

Audio-GD DI v3 is a cheaper alternative, too wink.gif

 

Glad your liking the Octave. I kind of miss mine redface.gif
