Re: What are the advantages of separately powering your tweeters?

It's probably going to help if you provide a link to an example of what you mean. As far as I'm aware, the NCxxx products are all mono amplifier modules in one configuration or another. I've got a pair of NC500 based monoblocks and they have no facility to separately amplify a tweeter channel. Are y...

Re: Cyrus ONE, issue 07 remove steps on volume/balance pot

I wonder if it would be a fairly easy operation to remove the sprocket like wheel on the back of the combined Vol/balance control pot in my old Cyrus One? If it's the same as on the Cyrus Two - yes, it should be almost trivial. You should be able to lift one end of the spring that sits under the ba...

Re: ATC SM40 - connection query

The active version of the SCM40 does seem to be pretty rare, but SCM50s and 100s actives come on the market much more frequently. I too have (almost) abandoned the idea of making my SCM40s active - as Ian has said in the past, it would devalue them too much because there is no easy way to do it disc...

Re: Another DAC XP Sig problem

Agreed - it should work. I've used this on a DAC XP (and also AV8s and AV5s) - and you get a digital out, irrespective of whether the input is coax or optical. Have you tried disconnecting the digital input that's not in use (or powering off the equipment the produces it) in case the clock on that i...

Re: DACXP Sig drama

Assuming the fault was not present when they received it (unlikely it would be, as it only seems to happen infrequently), I would expect that they would raise the "Inspection and carriage charge" of £60 and return it.

Re: DACXP Sig drama

When it happens, it's a weird effect on mine. Not only does the bass almost disappear, but the stereo image also does something odd - almost, but not quite, as though it has been mixed into mono - so everything central in the stereo image almost vanishes. Very strange - but as in the other thread, I...

Re: Repairs

Sadly Cyrus have been heading that way for years. When I bought my first unit (an MR2, oddly) they were very helpful, serviced it (out of warranty) for under £50 and sold me parts because I like messing around (e.g. I once converted a III integrated into a Power for a while, using some parts that th...

Re: DacXP Signature Problem

Hi, yes I've had a few problems with the DAC XP Sig. In my case the bass completely disappeared. My DACXP (not a Sig) does that too! Done it twice now, and the only way to make it work properly is to power it off and on again. I'm struggling to think ~how~ a DAC can suddenly lose all bass - it's a ...

Re: smooth black

I've seen both in smooth black, but IIRC it's a more complex picture, in that I'm fairly sure that for a while after crinkly black was bought in, you could order in smooth black at no extra cost. And then things were further confused by those such as this forum's AV8, who regularly swapped boxes so ...

Re: Cyrus AV5 Cinema Preamp Input Selection issues

I guess it's possible that it had been stored somewhere damp and got surface corrosion on the contacts in the DIL socket - if so then removing and replacing would certainly wipe away any minor oxidisation. What individual gain level do you have the two front channels set to? The AV5 is fairly sensit...

Re: Cyrus AV5 Cinema Preamp Input Selection issues

By all means open it up and see if there is anything obviously, visibly wrong, but in general modern electronics works at very low power level, so it's rare to see burned out or otherwise obviously failed components. The occasional exception are the SMD electrolytic capacitors, which have been known...

Re: Repairer needed Swansea

Without knowing exactly what items he has it's difficult to say, but offhand I can't think of any situation where the connection between the two would cause the transport not to power up, so it's either going to be the mains power outlet, the mains lead or something in the transport itself. If he ha...
