P.S.  Oh, and in the world of "geniuses think alike" I have both that Norah track and the Moby 18 transitions from We Are All Made Of Stars -In This World-In My Heart (great trio of dynamic but different sounds) in my demo list.  Interesting that you use Norah for both female vocals AND that double bass.  Nice!  Wonder if those ab changes also surface on the 24/192 or DSD (Analogue Productions, that is) versions of that track.

I forgot to mention about perspective, or trying to scale the magnitude of an improvement. Doing the sound stage depth test, I find that its very easy for the the ear/brain to hear very small changes in depth perception - for example, listening solely to the depth on the organ track, you can easily tell if one is deeper than the other - if A say is deeper, then B sounds "flat as a pancake" even though the organ may sound 100 feet away on A and is probably 95 feet on B but the relative shift in placement on the AB test is easy to hear. It is very easy for small changes to take on the perspective of an enormous change. So to get changes into perspective, I use the general test, and gauge my reactions to the change. For example, if you listen the next day, and don't notice the improvement, then you know what one was doing the day before was pretty small. So in essence you measure how long it takes for the improvement to fade and for one to get used to the sound.

 

Hearing an improvement after:

 

1 day  - small improvement

1 week - substantial worthwhile improvement

1 month - very substantial

3 months - very rare breakthrough events

more than 3 months - earth shattering change

 

For example, the Olimex USB isolator was in the 1 week category - I was still noticing the improvement one week on. So one week on I felt like I had still had a new toy, and enjoying the extra warmth and depth. But a month later, I was no longer thinking the system sounds better, even though if you went back it would sound much worse.

 

Now this won't work if the product has a big break-in period, or if you are constantly making small changes. It won't work too if your system is variable (good at certain times, bad at others). My designs do not have a big break-in period, as I know why the components age and I try to reduce the sensitivity to aging through design - this also improves SQ as well, as a component will never age to perfect performance. That said, Hugo does have a break-in, but this is more due to one getting used to the sound - breaking in your brain if you like!

 

I have only ever had one instance of the earth shattering change....

I think you can guess what that was - this is the Hugo thread!

A question to the OLIMEX USB ISO users

 

I bought a Olimex to use between my Synology NAS and the Hugo. However, it does not work, the Hugo is not recognize by the Synology; it is recognize by my MacAIr, though. Being my technical knowledge VERY limited, my only deduction is that it might need a power supply as it has an input for one. 

 

Have anyone faced this situation? Do you think the issue is the lack of a power supply? If so, will adding one will offset the expected benefits from the Olimex?

 

Thank you in advance for the support!

 

PS: the sound coming out from Synology > Chord > Naim amp is already excellent - however by reading the Olimex related threads, it seems it can be even better!

The Taurus is the only amp I own with the ability to do that, although many claim you need a tube amp to tame the HD800 treble - I've got mine hooked up to the Taurus as I type this and I'm not experiencing any issues with the treble. Source is the Marantz SA-14S1 and it's onboard headphone amp is whole lot 'spikier' with classical SACDs than the Taurus, at least at this early stage in the burn-in process. FWIW, I dont have any issues with the way the Hugo drives the HD800 - in the absence of the Taurus I'm sure I could live with it - it just doesnt present them in their best light. 


What differences do you notice in terms of sound and how much % different is it?

Please don't ask for percentages - it's all subjective and it comes down to your musical preferences and the way you perceive differences. Unless we are talking measurements, I just don't believe that percentages apply in this hobby - I'm also not a fan of the star system used by several magazines. I've already given my impression of the difference it makes to the sound signature of the HD800 - again, totally subjective and several here disagree completely. Unfortunately that's the nature of this hobby.

depends on which ears you are wearing doesn't it?  A listen for yourself is always the answer.

Hi, I'm using USB-ISO between iPhone5S and Hugo and it is working good without any external power supply.

 

If possible, I would recommend trying your phone to check if your USB-ISO is not broken.
