Here's the case I use. Fits perfectly:

I've decided to wait to see if the 2Go is something I'd like to have, before getting a case. If the 2Go's not for me, then Hugo2 will remain in a desktop position.

Isn't 2Go supposed to make Hugo 2 more of a home system, rather than Poly, which makes Mojo basically a kick-ass DAP?

I think it is a case of wait until the planned announcement at CES in January.

True; I have no idea what to expect. I just guessed that if there are holes to mount 2Go on the back of H2, it must be an enhancement for portable use. But yes, we'll have to wait.

2Go implies it is portable. I'm hoping / expecting it to be comparable to the Aeries mini with SSD, similar wifi options as Poly, battery operated. And price!

Hi all,

I know all of Rob's DACs up-sample but I'm trying to work out to what sample rate, for the Hugo 2, only out of interest because up-sampling is very popular with certain DACs (not that I'd do it with a Chord DAC). But I wanted to get an idea of how powerful this FPGA is compared to what can be done with Roon or HQ Player at the moment on a PC. Again only out of interest.

My understanding is the up-sampling steps for Hugo 2 are:

1 = up-sampling to 8 x original sample rate
2 = up-sampling to 16x
3 = linear interpolation filter to 256x
4 = linear interpolation filter to 2048x

Firstly I don't know if I have the above correct, so someone please correct me.

So do we always end up at 2048 x the original sample rate?

So if the original sample rate is 44.1kHz then we end up at ~90MHz ? And if the original sample rate is 192kHz then we end up at ~400MHz ? That doesn't sound right!

Or does EVERYTHING, regardless of what the original sample rate is, get up-sampled to a fixed rate sample rate, say ~100MHz ( = 48kHz x 2048)?

Cheers! @Rob Watts

The 2 go module is some way behind Poly in development. Though it's time to completion will be far shorter than Poly's as much of the original unit was had to break new ground. Please understand I'm trying to give you all enough information to indicate that something will be along soon but some of the details are still in flux. If you have a particular wish, throw it into the mix as we might well be able to accommodate it

A little late with my wish but if Hugo 2's Poly could accommodate an ethernet input (I know it will probably have WiFi already) that would be nice JF!

I don't think it uses linear interpolation. But I will wait for the authority (Rob) chimes in...

Makes sense.

I got the leather case from espy (Valentinum) for not only any travel, but in the desktop position. This may offer some general protection, including a spilled drink. It is very well made with quality leather.

I look forward to the 2GO announcement (poly on order) but given the amount of time to pass, I did not want H2 exposed.

Eaglewinds, well written review.

I'm moreso interested in the final ultra high sample rate figure! How it get's there, I'm not too fussed although would be interested if the above steps are correct.

[ CHORD EVENT ] Hey guys, we've got John Franks & Rob Watts in town and they'll be in Zeppelin & Co. on 18th September, Monday evening.

Please join us if you're in Singapore. It's a R.S.V.P only event, so here's the link to sign up >>> https://goo.gl/forms/BdKFkzVoeGdkp0BE2

Zeppelin & Co. FB Page >>> https://www.facebook.com/zeppelinandco/
Hope to see you

Nice to hear of a headphones shop I did not already know.
Well I won't be in Singapore until the second week of October. But if you have HUGO 2s both in stock and for audition, I'll definitely come by with my HUGO and my laptop and my HEKV2 for my first audition of Hugo2 .If it sounds clearly better to me than both my HUGO and my Benchmark DAC2 and your pricing is one I can digest,maybe I'll even buy one.
Are you actually located in the main Sim Lim Square Mall opposite Little India? If so,on which floor?
Or are you in the other Mall across the road on the Little India side?
PS. Do you by any chance have any trade-in deal on HUGO to HUGO2?
While I am asking one more question, do you also stock earpads for Sennheiser HD800?
Cheers Christer

Hugo2's steps are:
WTA1 16FS
WTA2 from 16FS up to 256FS
Lin. Interp up to 2048FS
WTA are dealing with sinc interpolation

16FS max is 16*48kSps
256FS max is 256*48kSps
2048FS max is 2048*48kSps

If your entry sampling rate is 96kSps, it will be up sampled up to 2048*48kSps
If your entry sampling rate is 196.4kSps (44.1k multiple) it will be up sampled up to 2048*44.1kSps

This is correct; but it's more than linear interpolation - it's actually a 3 stage filter running at 2048 FS. The first stage is linear interpolation, the second two stages are IIR low pass filters, all three filters work at 2048 FS.

As in Rob's quote, for normal processing it uses WTA filter instead of linear interpolation. Linear interpolation is used specifically for red or orange "high roll off" filters.
