Hmm, is that aimed at me?

I for one appreciate that you're doing this. I know it takes a lot of time and effort, but it's fun, and we like to see and hear this sort of stuff, obviously.
Lol, I think I'm pretty unusual in doing this. It takes time and effort but it's good fun. Part of this hobby, in my case.
OK, I want to comment on this. I'm what I guess you'd call a cable "believer," based on experience. Had I noticed that you were using generic spaghetti cables from turntable to Nano I would have strongly advised you to correct that issue ASAP. Skeptic or not, non-believer or not, I don't think anyone will deny that the link from cartridge to phono preamp is a critical one given the size and "delicacy" of the signal at that point. Your interconnects here really need to be shielded, and they should be of the highest quality you're willing to buy, seriously. Now you know, of course, this was an important lesson. Don't skimp on cables in a turntable setup!!!
Whilst I said as if using this pair of interconnects was something of impromptu idea, I've intentionally used the generic one in the initial stage for comparative studies. And I suspected the cable would probably matter with this setup as I agree that the signal of an LOMC setup is delicate and requires all sorts of cares.
I'm not however unclear whether it really is scientifically true that the signal really is all that delicate, especially the output signal from the amp. I was kinda skeptical in this respect however using a better pair of interconnects did make difference to my rather unbelieving ears.
Those actually look pretty nice, but FYI other AKer's seem to be fond of the Petra cables, which I think are actually intended for video, and are therefore heavily shielded, as well as fairly inexpensive. Not sure if the shipping costs would be worth it to you. As I said in my thread, I've compared everything from $40/meter cables to ones that retail at over $800/meter (!!!), and the very best were Grover Huffman's phono SC cable, which uses silver and copper ribbons, and a bunch of other stuff I don't entirely understand. At around $200 per meter I don't at all expect you to be willing to buy them, but I wanted you to know in case you ever change your mind, or have a friend with such a budget looking for perfection. Yes I know, that's a crazy amount of money to spend on cables for most people, but to me it's worth it.
I'm aware AKers like that Petra cable. At this stage I'm content with the QED. If I ever upgrade to a more expensive phono preamp I might consider another pair of interconnects!
Good evening all (yes it's been another busy and tiring day here), the 'interconnect' issue is interesting from a technical viewpoint.
Assuming both sets of interconnects had clean plugs and no 'contact' issues (an underestimated possibility imho), the only other likely real issue of importance is capactive loading on the output of the 'nano'.
I presume that the cables were connected on the output side of the phono stage, and cheaper interconnects are notorious for high levels of inherent cable capacitance, based on measurements I've done myself.
Once again, the issue of capacitance loading on op amp outputs can be a problem unless proper 'isolation' methods are used (resistors etc). If the improvement is that great with these assumed lower capacitance interconnects, it really makes me wonder about the possibility of capacitance loading issues.
David do you have any technical information on the design details of that phono stage? Interesting all the same. It's a very nice phono stage by all accounts and the reviews I've read. Regards, Felix aka catman.
I wholeheartedly agree with you Felix. I have so far found no meaningful difference between different cables especially in digital or MM cartridge setups.
I'm not clear about scientific evidence, however, with LOMC setups my impression has been that the signal is very delicate and susceptible to external frequencies/signals. With this Nano adventure I've become further convinced of my impression. But I'm not entirely dismissive of the possibility that it could be a placebo effect.
FYI, I always make sure that I clean the contacts with what I understand to be your recent favourite chemical, Caig DeOxit, be it generic interconnects or otherwise. So you can rule out the contact issue. BTW, I agree that issue is greatly underestimated.
It's interesting that your study revealed that the generic cables were 'notorious for high levels of inherent cable capacitance'. Perhaps that might have something to do with the improvement. But I feel that the improvement wasn't caused solely by impedance variances. The difference was somewhat greater than what is achieved by switching the impedance loading from 47k to 51.
I agree, I put the best interconnects I could afford (Van den Hul) on mine and the combined gear sounds great!
Now that's an excellent pair of phono cables to use! When I ever upgrade to a more expensive phono preamp I'll certainly consider getting what you're using myself :thmbsp:
