If someone is happy to send one definitely. Though wouldn't be able to do it for a while. Got a bit of a queue at the moment

Few questions:
1) Where are you all getting your updates on the Holo Bliss? I can’t find anything on the website. Would like to keep track of its development.
2) If I were to trade my Topping D90 for a Holo May but keep the A90 until the Bliss came out, would I notice an improvement through my Utopias/A90 with the May?
3) Retailer highly recommended Pathos inPol Ear for Utopias. Wondering if I could just get the inboard DAC, sell everything else and call it a day.

Regarding Bliss, Tim from Kitsunehifi, their US distributor, recently replied via email stating they've pushed back the launch date to sometime in first quarter 2022.

I'm thinking of going for the Bliss myself now instead of Volot cause, just not enough reviews or impressions on the Volot, it's like a meh, it works kind of thing with just one probably sponsored review available for real.
Meanwhile my May is definitely a keeper but kind of feel the disbalance of running Soundaware P1 with this.
I wonder what the price is gonna be like for the Bliss though, hopefully not much more expensive than the Preamp, like say maybe 3k at the most?
I'm now leaning towards getting the Spring 3 KTE first and perhaps a solid tube amp soon thereafter. Then wait for the Bliss if the Volot, Soloist 3x Grand Tourer or Oor doesn't end up taking my money first and assuming the price is in the same general ballpark.

Thanks for the update. I'm also very interested in this
I'm personally a big fan of tube amps with the Utopia. My current favorite pairing is with the HA-300 but the volume pot doesn't have a ton of adjustability within safe listening SPLs. GS-X mini was also a really good SS performer for the price that I recently demo'd at CanJam.

I plan to sell my Holo May L2 but haven't listed it yet. Approximately 600 hours of use. If interested, please send me a message.
What are you buying instead?

Just a very wild guess: https://www.head-fi.org/threads/four-years-after-the-l-k-s-da004-the-musetec-da005-dac.953177/
In my understanding, @DBB1 was happy with the musetec but curious, put money where is mouth is, and this is the conclusion. I’m also guessing he has better use for 6kUSD than a large 2 piece component that gets little attention

Exactly. See my review above.Just a very wild guess: https://www.head-fi.org/threads/four-years-after-the-l-k-s-da004-the-musetec-da005-dac.953177/

You cannot capture a square wave, true NOS impulse response, or other signal that has content outside the nyquist frequency. It is mathematically impossible.
When we generate as perfect a square wave as we can, it looks like this, that is assuming you have sufficient bandwidth, in the case of this screenshot, the ADC is running at 2.5mhz.
Now if we change nothing other than the ADC sample rate, to the 192khz that JA was running:
Now we can see that the square wave is not perfect. Not because it isn't perfect in reality, but because we are not sampling at a high enough bandwidth to capture it.
TL;DR: Dear Holo user. If you hear sea weaves, switch off scrambling.
It was a joke, but on-topic. Initially I wasn't intend to respond to this tutorial. Due to the derogatory comments on the bottom I just skimmed the content, now I see it as an interesting follow up, of course after solving a main bone of contention of using digital filters, it is a simple matter to prove. To all: This post is not for disputing digital filters use (it will follow), but something else.
Of course, I am not going to claim anything above the Shanon/Nyquist like MQA designers do (another joke). However in my view 1kHz square wave should not generate such intense ringing when a Nyquist frequency is 100 times above. At a Nyquist frequency (~100kHz) of A/D converter, amplitude of harmonics is ~100 times lower, it is seen rougly from the screenshot. A picture as above is more appropriate if A/D sampling rate were about 20kHz, but it is 200kHz, far more.
Therefore it comes a question. Did you get similar results when testing NOS DACs, other than May/Springs? Please answer this question before bringing up another tutorial.
I know I won't get many likes for this post in this thread, but I would like to point at the interesting behaviour when switching A/D sampling rate. A noise floor @2.5MHz is rasing to 1uV, very significant comparing to 192kHz. It shouldn't be so high. The added noise is spread continuously across the frrequency range, masking internal peaks. It means that it might be some other HF component contained in the source (with higher intensity than 1kHz square wave spectrum in close proximity to 100kHz), it is completely undetected by the analyzer. With a lower sampling rate it contribute to ringing and with a higher sampling rate is averaged, increasing noise floor. A spread sprectrum modulation comes to my mind.
For all others. You may not understand these technical issues. One things is beyond dispute. The Audio Precision SYS2722 is able to capture 1kHz NOS square wave without visible ringing. These examples are captured by JA using the same analyzer:
1. Audio Note CD-4.1x CD player. This one I know is very well sounding player, true NOS design.
2. Audio Note CDT One/II CD transport & DAC 2.1x
3. Peachtree iDac D/A converter. This is not ladder type, but Delta-Sigma where (I think) designers managed to bypass the internal digital filters (ESS 9016).

Just a quick question for the tech savvy people, is it posible to conect the I2s from either the Spring or May directly to the eARC output on a Sony TV?
No. I2s and hdmi are not the same and connecting an hdmi device to an i2s device may damage one or the other.
They share the same connector/cable but the protocol is completely different
