Yamamoto YDA 01 DAC

Hi,
Pani, I have the SS version
and use the PS Audio PWT as transport(ASI Liveline digital cable) this combo has been wonderful.

Srajan used the Yamamoto as his reference for quite a while.Given his very high praise of the Metrum Octave this certainly got my attention. We must hear things very similar as his strong recomendations have so far been 100% accurate based on my own personal listening followups.

Best of Luck,

Pani, the only NOS DAC I heard was the Audio Note DAC 5 at CES 2010. It was for about 20 minutes(show conditions) I could`nt form a solid conclusion, but it did`nt really impress under those circumstances.

The Metrum Octave is quite a different approach i.e. much simpler design(good!)non audio chip(ultra high speed industrial, rather than old Phillips chip). It eliminates seperate I/V conversion and output stages(industrial chip intergrates these functions again very simple-fewer parts) also much effort into the power supply. Based on the differences it`s said to be a better-modern design than previous NOS DACs. We shall see.

Hi Charles, I just went through the review of Metrum DAC. It definitely is intriguing and for the price is just surprising. One thing though, Srajan did not at anytime talk about the Metrum Vs Yamamoto in his review (sonically). He spoke about other players but not Yamamoto. Now that has got me thinking. Did you talk to Srajan personally on this DAC and ask his views about this vs Yamamoto ?

One thing I know without even listening that Burr Brown DACs generally get the tone and timbre very correct. Considering that the YDA01 has been made by a hardcore Vinyl guy I cant think of it as sounding typically digital. Even Srajan had said in his YDA01 review that it just doesnt sound like digital is being processed. Both these factors together gives an amount of confidence on the Yamamoto which can lead me to go with a blind buy without hesitation.

But still, since you are getting a Metrum, I will wait for you to comment on it before taking the next step. How much did you pay for the YDA01 ? Is it switchable between 110V and 220V ?

Pani,
This is why I suggested you read the Totaldac review for context. That review compared the reviewer`s Yamamoto(which he loved) to the Totaldac and preferred this component. Srajan found the Metrum and Totaldac sonic equals(Metrum is 1/5 the cost!). Pani did you note his comparison to the APL NWO-M? very impressive(more tone,body and presence). As I mentioned before the Yamamoto sounds fantastic(really as good as anything else I`ve heard so far), but this Metrum seems a different level upwards.

He made it a point to emphasize the superior "resolution" and wide bandwith performance compared to typical NOS DACs, yet maintaining a profound analogue like and organic character(mentioned sevral times).He made a point that upper frequency detail,harmonics and decay are very much intact(no rolled off highs). Remember the Metrum is R/2R, based not delta sigma chip(Yamamoto). Srajan obviously thought highly of the Yamamoto(and for good reason) but feels this modern yet simple R/2R designed DAC is quite special. Analogue gestalt and rich tone combined with superior resolution not found in most NOS DACs(weakness of typical NOS DAC). You should read the current 6 moons review of the April Music U3 USB converter where 4 DACs are compared and again note the Metrum comments, very clear opinion.
Best Regards,

Pani,
Forgot to answer other questions.
1)Payed 2500 USD for YDA-1. JAN. 2010
2) No switch for 110/220 volts
3)Srajan sent me an email saying he did`nt directly compare the YDA-01 and Metrum. But said reviewer Joel thought the TotalDAC clearly bettered his own YDA-01. Srajan considers the Metrum and Totaldac as equally great, thus by triangulation he`d say the Metrum would out performs the YDA-01.
