did have a listen to that snare on 'Brothers In Arms' again...I don't really know. It's definitely not fuzzy but it is slightly softer and just more 'masked' than I recall it with the DCB1. I had level quite low though.

I used to have another set and the matching speaker cable too - I was always a 'full loom' man - but someone came round and bought an entire system off me so I bundled them in with it as he had no cables of his own.

Ah...."Hybrid conductor" Seems tey have OFC strands and on thin "solid core" OCC....thats a shame. I thought it was too good to be true. I think a PC-CCC session may be worth while? I have a 1.2m and a possibly a longer pair...If you fancy it? Looks like i may have a fair few strike days available to visit with lol |

Ok, would 1.2m do for the link between pre and power with a temporary reshuffle? |

That is a fantastic shout Bigman80 and macca. Great opportunity to hear what the pc ccc sound like in a different system. This forum is great. |

Turns out I didn't get rid of the hum, I only checked the left channel, right channel now has it, left is silent.
Turns out that my tape did not hold the cables in place. They are about two foot too long for the application so there's plenty of opportunity for them to wind around the power cables, it's like they are attracted to them or something. Plus they are stiff, you can't bend them into a set path as they just bend back.
Got a new roll of duct tape out and done a rough job of taping them up but it's only reduced the hum a bit. Need to get back into it properly later on and sort it properly. What a pain.

macca , I would go for a cheaper fix and try some pipe insulation around the cable, you only need a couple of cm of the stuff and it keeps wires nice and separated. Worth a try for next to nothing.

Have to agree re: a cheaper fix Pete, unless something more complicated is occurring. Been meaning to update the cable management thread I started as I'll be utilising some of these type, simple but what look helpful bits, towards neat, separate / separated cable runs, first good chance I get. There are other similar options a plenty on eBay. www.ebay.co.uk/itm/313895811061?var=612614409548www.ebay.co.uk/itm/374010330971 |

Worth a try for next to nothing. good tip that, I will do that if I can't sort it otherwise. I don't think it's anything weird, left cable was round the power cable - left channel hum, now it's the right hand cable, and hum on right channel. So makes sense. Couldn't fix it today as we had a power cut, damaged cable somewhere, so will be the weekend now. |

Okay so after listening to some recordings that sounded terrible, and still having the hum in right channel, I've rebuilt the rack so it's lower and put in the much shorter Spotfire cables betwixt pre and power. ) I Know the Krell KSA50S is only borderline compatible with passives but I did not expect the longer cable run to have that much effect. Just no top end. Bass wasn't great either, overall the sound was pretty dismal with the long Belkin cables in place.
Much better now, no hum and less top end roll off (although I think there's still a bit).
Was a bit concerned that my DAC wasn't seeing any signal from the transport. Had a bit of a FFS! moment before realising the digital coax cable was still lying on the carpet where I'd chucked it when I dismantled...

The BT2 isn't passive, it's an active circuit with dual buffers per channel. That means you can run really long cables with absolutely no detriment.
It currently has no gain (can be added) which is similar to having a passive In the system, but you don't need gain with the output signal size from a DAC or any decent phonostage.
I suspect that it may be that you are hearing an issue with the cable? Maybe it's high capacitance due to length?
That's been a cause I have experienced for music to sound rolled off in the past.

Not using the long cable now just Spotfire.
For whatever reason it's not quite right.

Tracking down ground loop: Thought I'd try the obvious first, is there a problem with a plug (earth wire come loose)? The CD transport and the power amp cables both have old style plug you fit yourself. (Krell supply a very thick mains cable with the KSA50S so it doesn't catch fire when you are caning it). Opened up the plug on the amplifier cable, found this:  WTF? |

anyone got any idea what this bit of wire is? You can see live, earth and neutral wires all go to their respective connections but then there is this fourth bit of wire just sticking out?

Very strange. Just looks totally unnecessary, like the spiders legs you used to see emerging from 1970s bikini bottoms. |

That was a phenomena that extended into the 1980s, especially if you holidayed anywhere where female Germans were present. Anyway other than the mystery wire I can't find anything wrong with the plugs, all connections are secure. |

F#ck me.....that's the braid/shield off the mains cable. It SHOULD NOT be hanging loose like that.
Have you got a different cable?

yes I've got another thick cable I could use. But that one's been fine like it is for a number of years. Can't see it being the cause of the problem. But I shall suck it and see (not literally, obvs).

I've trimmed it off now so it's level with the outer sleeve.
