Chord Hugo - Page 175

Ak120 is very picky on the optical cables, like a spoilt brat
post #2612 of 14222

Has someone being able to compare ZX1 (USB) >HUGO  with  AK240 (Optical) >HUGO ?  

 

I much prefer the UI of the ZX1 and love the fact that we stream on it Qobuz HD or Spotyfy to discover new music...but I don't want to trade for this an inferior SQ.

 

thanks

Let me steal this from someone else (http://www.activebass.com/a42--Understanding-Basic-Electricity-of-your-Amp-and-Speakers):

"First let me explain it in terms that everyone can understand. Think of your amplifier as a water faucet or hose bib on the outside of your house. You connect the garden hose to the faucet. This is the wire going to your speaker. You then connect the end of the hose to one of those spinning water sprinklers. This is your speaker. Now. The amount of water PRESSURE is the VOLTAGE. The amount of water FLOWING is the AMPERES. If you have one of those little spinning water sprinklers for the lawn it does not take much to make it move but if it is a heavy industrial sprinkler for a large field it takes more water pressure and flow to make it move. The pressure and the flow overcome the resistance and the RESISTANCE is the OHMS. The total amount of land getting water is work, and the WORK BEING DONE is the WATTS. Also, the size of the hose will effect the amount of flow so whenever you do wiring on your speakers be sure the wire size is large enough to handle the flow."

Given the above, you can see that OHMS by itself doesn't mean anything.  Its the WATTS needed by a speaker/headphone at whatever OHMS is what dictates how hard your amplifier will need to work to drive a speaker/headphone.  While headphones may have much higher Nominal Impedance (OHMS) than most speakers, it doesn't require anywhere near as many WATTS normally.  You can compare WATTS needed by A speaker/headphone to B speaker/headphone by normalizing the ohms.  So Speaker A wants 50 watts at 8 ohms and Headphone B is .5 watts at 64 ohms, would make Headphone B similar to 4 watts at 8 ohms. btw, when they say 50 watts required, they really mean watts RMS.

Statistics around efficiency (db SPL Vrms) or sensitivity (db SPL Wrms) are interchangeable with some calculation.  These calculations were meant as a way to give you relative apple to apples comparison.  However, it does not really help in determining if your amplifier will drive your speakers/headphones correctly beyond a brief guideline.

The danger is under-amping your speakers/headphones.  Over-amping isn't as big a danger as long as you control volume correctly and don't blow out your speakers.  Under-amping is the danger as not providing enough volts can cause the type of clipping that will cause permanent damage to your speakers/headphones.  This is why I am scared to plug my B&W 805's into Hugo as B&W says it requires a minimum of 50 watts at 8 ohms and Hugo says it provides 1 watt at 8 ohms.  Also, remember most of the numbers quoted are typically average and the variation is going to depend on the frequency being played.
Nice one crashem,did you do that calculation with the dc ohms law,the 4 watt to 8 ohms?

My music diet is changing thanks to Hugo & HD800, I now listen to a lot more classical - they just sound so beautiful & musical with Hugo :)

No kidding.  The Hugo's liquid-ness + the HD800's atmospherics, I'm listening to more opera.  I'm getting old.

 

Damn kids with your compressed music and ibuds, get off my lawn!

 

ps - Listen to Alison Krauss - "Ghost in this House" from her concert.

Hello to all of you!

 

 I'm on my second Hugo as I had to send the first one back for a little repair and my dealer was kind enough to exchange it for one with the new casing!  I use it as a dac only but I may get some nice headphones later on.

 

Cheers!

are you using the Stock HD800 cable with the HUGO ?

Hi-Fi+ just released an excellent review of the Hugo in their May issue.

The reviewer compared it to a Auralic Vega/Taurus system and said that although he slightly prefered the Auralic system overall, the Hugo came "tantalisingly close to matching the overall performance."

I was disappointed that the reviewer did not go into detail about the Hugo's performance as a DAC only.

i have been listening to a friend's Auralic Vega in tandem with my Hugo over the last few months, and I would say that although the Vega is a fine DAC . In the long term it is not as
Natural-sounding as the Hugo, it is more immediately impressive, but over the long haul is more fatiguing and just not as musical and realistic, Therefore not as good IMO

In relation to Sleepy guy's comment regarding : listening to more classical music, I think this illlustrates how natural -sounding the Hugo is . Acoustic timbres and voices just sound mega-realistic and are truly breathtaking!

Sorry Sleepy-0ne's comments! I'm mega tired from listening to Hugo through T1s and LCD xs

Hi everyone

 

I just download DXD music (352kHz) from 2L.

 

But when I playing the music by HD USB on Hugo,  Hugo just show the green light (96kHz)

 

Someone know what's the problem?

 

I use JRiver 18 as player....

 

Thanks!!
