Peter - I guess the filter profile for these Orelino's is going to differ from the MkII's to some extent as the 12" drivers cannot be driven so hard before distorting. So I need to think about some of these changes you are proposing. I am not at the stage where I want to make significant changes just yet until I get used to what I have now. Although I did take the 90hz notch out.

Thanks George.

From the pic, the Emersons look like they should have a gold-plated centre pin. The ones that I received from Mouser definitely do not have this. But the packaging stated the exact same part number.

The Oelbachs look nice - I'll probably try to get these if I can at some point (again, for purely psychological reasons and being able to sleep well at night).

Incidentally, I have asked for my K_02252_D cable from eBay to be cancelled (I haven't received a reply from the seller yet but am assuming it will be OK to cancel). My thinking is that if I'm going to bother replacing the cheap cables I'm already using then I really want the 'best' I can find (again for purely psychological reasons). Otherwise I may as well just keep my current cables, which sound great anyway.

Mani.

Intrigued by vrao's question on 'Good BNC to RCA adopters' have searched  a few.
The only one with tech details, most important would be Freq. Range, is the one Mani already suggested: Emerson 27-8110, Fr.Range: DC to 2GHz.
No other manufacturer/distrubutor is stating this information. And here are few suggestions, from easy available to 'boutique' one's:

Emerson 27-8110 @ Mouser Part#: 601-27-8110

Hi,

Note to boleary & vrao.

When I have a look to the diagrams of  Reply #97 by nik.d I'm "nitpicking". Beg your pardon.

Both diagrams are showing nearly no differences (nothing due to the small scale) in the audioband up to 20KHz within the single and the double shielded cables, and we should hear no deviations in a blind test until otherwise proven.

Joachim

EDIT:

Mani is very enthusiastic with his intermediate "cheap" BNC cables, and it will be interesting to read his comment about the new cable (K_02252_D).

Peter, I noticed that my DSP software looked slightly different from your screenshots and was going to mention this. But then I thought it probably wouldn't make much difference.

Mani, yes, it is different and this is unintentional. Whether this really can matter anywhere is unknown, and best is to use the settings with the 2.9 version with which I created the files. Notice, like for VJ, that when no problems are encountered all can stay as it is. Otherwise I have a new package ready + procedure to apply (which I just sent you by email, Mani).

We'll put the outcome of the "repair" in this topic.
Peter

Thanks for the reassurances guys. Actually when I went to bed it occurred to me that it couldn't be something too drastic - the DSP USB connection still works, so the DSD unit must still be powered up and working.

Hi,
Can someone explain why something like this would not be appropriate?
http://www.trilogycoax.com/pdf/wireless/aircell_catalog/AirCell_Catalog_Plenum.pdf
I see the following interesting features
Item: AQC012J50
Capacitance: 72 Pf/m
Velocity of propagation: 95% speed of light (RG142 @ 70%)
Dielectric: Air

What is different is the corrugated jacket.

Thanks,
VJ

P.s Anyone with recommendation of a good BNC to RCA Adapter?!

No mention of any steel conductor in the RG142B cable that I ordered:

http://www.l-com.com/multimedia/catalog_page/2K14M1_165-RG142B-U-and-RG213-U-50-Ohm-Cable-Assemblies.pdf

The order was from here:

Hi,

both same cables (RG 142)  are a "silver-coated copper-clad steel wire". Conductor dia=0,95mm.

Hi Mani,
I was able to use the settings myself, for a week now.

The bass is great for electronic music. But for Jazz and classical it's a bit off balance.

Hope your settings are back up and speakers working again.

Regards,
VJ
