Imported the latest offering from ECDesigns, the Power DAC B. Along with it the UT92, the Xmos based USB to Optical converter.

Cables included: The power cable to DAC, optical and usb for the converter.

DAC and converter are sleek, simple brushed aluminum finish chassis and short, simple cables, which mean business and nothing fancy here.

And guess what, which ever premium cables I tried using, killed the sonics. So I realized there is no point wasting time, rather give it a good listen using the stock cables.

Well I already own the R version and the difference between the both R and B sonics is none except:

R comes with a remote and you can vary volume from mute to max and check for bit rate perfection.
R drives headphones very well coz of remote.
R has power supply in separate chassis. Like an adapter.

My chain: Windows laptop with JRiver, mostly streaming Spotify premium. ECDesigns Power SAC B, DHT Tube Preamplifier 6L6 Tube Amplifier monoblocks, DIY BS 2 way 89dB.

A little about DAC B: It’s a chipless, R4R, no caps / opamps / transistors active devices / chokes / transformers, nothing in signal path but only resistors for D to A conversion and gain.

Listening impressions: I am too lazy to use a flowery language to touch upon the different nuances of music it puts forth though you can engage me endlessly on the technical discussions, so I will just say this.

When I listen to my setup, time flies, I am stuck to my seat endlessly, I start procrastinating on the jobs in hand, become lazy, unproductive and finally force myself to get up, feeling useless.

Most striking aspect: Very natural, effortless, relaxed and open rendition of music. Full frequency response, vocals to die for, macro, micro details and a low end which is hard to describe, are all “given” ! I call it an “analogue machine with digital precision” !

There is actually nothing “digital” about this DAC. How did they omit the digital part while strictly working in the digital domain ????

Here is the DAC playing in my setup:

The R model is resting these days, taking a break….

Way above, as some users say….

The fractal, earlier model was already rated way above.

This one is quite a notch above the fractal itself.

I still don't get it why they use a jitter prone optical interface as their only input.

It is impossible for them to have less than 4ns of jitter on an optical interface.

Since they anyways built a usb converter, why not build a usb to i2s which will be significantly better.

They have opposite views on this. They consider optical input to the DAC as the most optimal.

How? A minimum of 4ns of jitter is okay for them when others are doing a thousandth of that?

This is more a question about why as till date every single dac I have heard sounds their worst via optical.

Why not ask them directly ? Shoot them for answers at their website.

They are masters of digital domain. Their architecture is completely different than what others are doing.

I don’t mind as long as it sounds absolutely fabulous and better than anything I have heard till date. And many others share my views with 10X DAC already in their pockets.

Been on I2S road too…

sure but if you have heard the qutest, what are some of the sonic differences that exist between this and the qutest in your opinion.

Two friends owned and heard both.

Both are of same opinion: ECDesigns DAC is most natural and relaxed sounding with no dearth of details and wide frequency response. Not an iota digital glare….

I have built / played legendary chips DACs. The vintage TDAs, PCMs and ADs and CL.

Check online, now quite some reviews are pouring in…

One review is right here, on this very forum. I imported it for a friend when it was just introduced.
