Wow, $5,400 US.  https://www.whathifi.com/news/chord-unveils-hugo-tt-2-dacheadphone-amp-high-end-2018

 

I don’t believe the US price had been announced. It’s not just the GBP-USD conversion of the UK price, you know!

I think that the success of TT2 will be heavily influenced by launching a dedicated M-scaler at a reasonable price. 

 

+1

 

The Mscaler/TT2 combo should be close or equal to the Blu2-Dave, at a fraction of the cost. Just no CD player.

Is there a good explanation of DSD decimation somewhere? I have no idea what that means!

Here's a discussion in DAVE thread about it and a youtube source (Rob Watts) explaining it.

Thanks Mark.

 

I followed the reference and watched the video, but nowhere have I found what decimation is.

 

will keep digging.

So I guess "decimation" is nothing more than the "process of reducing the sample rate of a signal" - https://en.wikipedia.org/wiki/Decimation_(signal_processing)

 

In English, the word decimation has connotations of doom and destruction - armies being decimated in wars, or the ancient Roman practice of decimation:

 

...was a form of military discipline used by senior commanders in the Roman Army to punish units or large groups guilty of capital offences, such as mutiny or desertion. The word decimation is derived from Latin meaning "removal of a tenth."

 

 Thankfully, in terms of sample rate conversions, DSD to PCM decimation is relatively benign, as DSD is 2.8224 MHz, which is an integer multiple (16x) of 176.4 KHz, or 4x of 705.6 KHz.

 

Beyond this, every DAC does voodoo to the signal presented to its inputs, so best not to worry too much about it. Either it sounds good or not!
