 With that nice Classe integrated amp, just take the RCA output to the amp, starting up the Hugo by holding in the crossfeed button while powering it on, and use your Classe volume control and remote and let the Hugo do its number crunching.

 

Doing the crossfeed button only set the RCA output level to 3v which is higher than the usual cd player output level which is around 2v. If the input sensitivity of the integrated amplifier is not great, it would result in clipping.

 

I find there are 2 methods two connect hugo to integrated amplifier: 

 

1. connecting hugo to line level input of the int. amplifier but reduce the volume of hugo so it will output at a level which more less match the line level input sensitivity of your int. amp. In this case, you are not using hugo preamp, and you can use the volume control of your int. amplifier. This is similar to connecting a CD player to Int. Amp. But reduce the volume of Hugo to avoid clipping.

 

2. connecting hugo to line level input of the int. amp., but set that input as home theather bypass (if your int. amp has this function). this will result in bypassing the preamp function of the int. amp. and using the hugo as dac and preamp. volume control of the int. amp. will be disabled hence you need to adjust volume on the hugo for listening.

 

My int. amp has the home theatre bypass function and i can compare the sound quality using each of the above method. In my case and IMO, sound quality is better using Hugo as preamp.

Hi Alubis,

 

My Hugo's manual say RCA output is at 2V by holding Crossfeed button while turning the unit on, not 3V.

I hear hiss with the Hugo, but very slight and not an issue. When I was using iqube as amp the hiss was stronger and noticeable. I recall post of Rob regards the SE846 he confirmed that based on specs there will be hiss.

The Shure SE846 is very sensitive, the most sensitive I have seen, and Hugo's residual noise at 5uV A wt. would be just audible. You could use the SE846 attenuator, but that may upset SQ. Hugo has a very big dynamic range of 120dB, but it can also supply a lot of voltage - 5v RMS and a lot of current - 0.5A RMS, so it will drive difficult headphones too. Having a lot of voltage gain has the downside of bigger residual voltage unfortunately! Having said that, the best I have seen on residual voltage is 3.5uV, and I have seen a lot of headphone amps or DAC's with a lot more than 5uV!

It is probably going to be mostly of interest to people in Europe, but I found that the sockets on the Hugo will take the plugs that fit up to a 9mm Van Den Hul cable. That is, any VDH cable with an outer dimension up to 9mm will fit the Hugo. That means it wont fit the 3T The Mountain or The Cliff (which are 11mm) but will fit any that are smaller.

Chord had confirmed, and even on this thread, that the preset output is indeed 3V instead of 2V as stated in the manual.

Really enjoying the Hugo a lot everywhere lately....
