Anyway, why do I need a balanced portable amplifier?

post #1 of 3
Thread Starter 

I’ve just ordered Cypher Labs’ Algorhythm Solo –db. It has a balanced output port for connecting it to a balanced amplifier, like the “SR-71B” and the “The Intruder” from “Ray Samuels Audio”, or the “The International” and the “Rx MK3-B” from ALO Audio. By the way, are there any other portable balanced amplifiers around?

 

Anyway, why do I need a balanced portable amplifier? I already own the TTVJ Portable Slim (having “just” single ended connections) which to my ears sounds quite fantastic with my Sennheiser HD 650. Now, I’m not a technical person, but isn’t the purpose of balanced cables to eliminate interference from powerful radio signals and strong electrical currents, running in parallel with the audio cable, such as a sensitive microphone cable on stage surrounded by lots of electrical cables for lighting, etc.? How much interference can a 1 inch or so single ended line-level analog interconnect cable pick up in a normal home? Enough to be audible? Really? Please convince me! Perhaps a balanced cable from the amp to the headphones would make some sort of difference, but I really doubt that too!

 

By the way; is the left and right cable in a balanced headphone cable really balanced, or is the sound just balanced until the moment it leaves the balanced output port on the amp? In that case, a balanced headphone cable would be more or less useless, no? As I said, this is not my home turf.

 

Another thing I just can’t understand is why I should invest USD 265 on a “Reference 8 ‑ Silver/Copper Mini to Mini” interconnect cable between my CLAS and TTVJ Slim. I mean, how much can the analogue signals degrade while being transported an inch or so in a normal home far away from high voltage cables and strong radio signals? Again, enough to be audible? Really? Please convince me!

 

It would be nice the get some response from the sponsors/manufacturers as well, but they never seem to get into the discussion. I wonder why?

 

It seems to me that the whole thing with super expensive cables versus decent quality cables for portable use is a lot more smoke and mirrors than it is science and/or audible. Please note that I’m not trying to be provocative. If someone could prove me wrong, I’d be very interested and exited, as it would mean even better sound quality.

 

In this context, I don’t give much for arguments of the type; “After I upgraded to this super expensive headphone cable, I swear to God I entered into audio nirvana”. However, if you’ve been able to pass a blind test under trustworthy conditions, i.e. performed by someone other than yourself, I would be more than willing to listen. Anyone?

Unfortunately there is so much gear that sounds "amazing". Nevertheless, thanks for your reply and I'll try to investigate it!
