Please forgive ignorance, but is it only XLR which are balanced?

indeed, only XLR cables are balanced (you need 3 conductors for a balanced connection, +/-/ground).  rca cables are unbalanced, as they only have 2 conductors (+/ground). 

 

the BHSE's topology is such that it shouldn't make too big a difference which you use, though the balanced input would be ideal.  more importantly, you should ensure that your source's balanced output is truly good quality, and go from there (if it has a crap balanced output system, like a set of inverting opamps, then you might as well avoid it)

Thank you Doug. Do you have any idea as to whether Bel Canto Dac 2.5, which is balanced according to their website, is good quality or not? If it were the case and if I understand you correctly, it would mean that I would be better off with the 15 dollars XLR that Justin recommend than with my 150 dollars RCA, is that correct?

No need to apologize.

He was referring to the previous posts about the possible new color schemes of the BHSE.

So my girlfriend just agreed to pitch in for Zu speakers if we get the purple finish...Maybe it'd work for a BHSE... :D

Hi guys, I would like to ask is there an appreciable sound difference between the DACT and alps RK50 version?

 

Also has anyone measured how much the BHSE pulls from the socket? is it a full 200W all the time?

 

Much appreciated.

post #2754 of 5871

The BHSE is Class A so it always draws full power or close to it.  It's not 200W though, that's T2 territory but the BHSE is more like 130-140W. 

post #2755 of 5871

I earlier posted a measurement of 180W (and 205VA) on my UK 230V version.As sprizer says, it's clas A, so it was no surprise that the measurements didn't change whether music was playing or not. It did fluctuate slightly to follow the fluctuating supply voltage.

No difference in sound between both pot.

This is close to the 200W that Headamp specifies on their website.

Is that as a result of you doing a listening comparison test of both? Or by theory?

 

This question (like many) has been asked several times before in this thread, and this is the first time, that I can recall, that someone's given an opinion.

I own BHSE with dact. Listened to one with rk50

EDIT : I still own the BHSE. Fantastic piece of equipment. It would take a BHVSE for me replace it. V = VERY:D:D
