Aurender


I have a Korean car, watch KDramas and even listen to some KPop, but I don’t get what Aurender is doing.

I’m currently in digital hold given that my new Holo DAC died, but intend on listening to my IFi Zen stream and look at upgrade paths.

Some of the most respected members of this forum swear by Aurender, so it must deliver, but here is my point of confusion:

1. Coax and AES are the preferred outputs, but higher bandwidths require dual AES out, but I don’t have dual in on my DAC.

2. Aurender’s top models claim to have great clocks, so why not pass this on to the DAC via I2s?

3. Top Aurenders accept external clocks and I assume this is used with a DAC that accepts external clocks, but why bother when I2s would take care of this?

4. The argument against I2s is that there isn’t a standard, but this isn’t a problem in most implementations.

I’m sure that I have misrepresented things above, so please correct my understanding.

I bookmarked your website. Holo is sending me a new DAC. I’m guessing that production is a challenge. You seem to have a wide array of products.  I bet your R-2R Tube DAC sounds quite musical.

I appreciate oddiofyl input. However I have not had any issues with bluos for weeks now. Not a single hiccup. I don"t have vault, just using the NODE to stream Qobuz. And the reliability is awesome. Aurender will have to make huge strides towards android reliability before I ever consider it. And as far as the Aurender sound being so much better than the NODE, it all depends on how you set up your NODE. No need to keep rehashing how I do it, just look at my system, fully described there. I honestly don"t see what I am missing sound wise vs. Aurender since my streaming setup is at least up to par with both my vinyl and CD setups, and they are no slouch, also fully described in my system. If Aurender works great for many, great, but it's far from the only game in town and similar performance can be gotten for much less money in my experience. Whatever Aurender did to get such reputation on this site is obviously genius. 

@vonhelmholtz Just seeing this thread now and weighing in.

First, sample rates higher than 176-192KHz are nowhere near as important as the quality of the clock and the protocol. With that said, I would take a digital source with a quality clock maxxed out at 192KHz using AES over 768KHz USB any day. I am in the camp that believes USB is noisy and fatiguing in comparison. One case I can make is using USB from my $24K Aurender N30SA into my $38.5K T+A SDV 3100 HV. Where USB will use the T+A’s reference clock, even with 768Khz, I still prefer AES and the Aurender’s clock with 192Khz sample rates. The quality of the clocks in Aurender’s higher end units is very admirable and the N30SA (and the T+A DAC) is one of the reasons I’m debating so hard on whether I should give up on vinyl completely (you and I have discussed this). Many other endgame DAC manufacturers also prioritize AES, such as Berkeley, and AES is a professional protocol used in the pro audio / recording / mastering / production works. It is NOT a legacy interface.

Audiotroy mentions that Aurender can’t run Roon because it’s processors aren’t strong/fast enough. This is by design. By utilizing a low processing power architecture, Aurender can achieve lower noise floor, better separation, and just more of everything. Conductor is a proprietary platform to work its best alongside this low processing power environment. On the contrast, there is much debate about the “sound of Roon”. There was a fairly lengthy thread on this where I also commented on the elements that make a quality server/streamer (a robust linear power supply, low power, low noise, isolation, and clocking).

Also, I’m not aware of Aurender having any issues with native DSD playback. The Conductor platform allows users to choose whether they want native playback, DSD over PCM (DoP), or conversion to PCM. In this case, it boils down to the DAC’s supported formats.

Agree with others on i2s. There’s been a lot of hype, but implementations vary.

No surprise, blisshifi being an Aurender dealer. A mention of it would be nice no matter how many times you post. Just saying.
