Real experience - Balanced or Unbalanced between Luxman Pre & Power Amps

@photon46 appreciate the response.  Are there any particular interconnects or XLRs you'd recommend?

Rest of the system is on par with the amps (ATC speakers, Michel Gyro Se, Koetsu Black, Gold Note phono and psu, blue sound node with chord qutest dac and separate PSU).   All plugged into an AQ niagara

I’ve tried Blue Jeans and they are about the quality of what comes with new components. I don’t know anything about QED.

Typically I recommend DHLabs for budget interconnects. But since Luxman is very hot on the top end and lean on the midrange I recommend Cardas Clear Beyond… they are warm and musical these should be very complementary to your system.

Balanced!!!!!!!

Other than preferring to use balanced cables I hesitate to offer advice beyond that. Your Luxman pair is voiced a little differently from mine and your speakers aren't voiced the same (mine are Tidal Piano Ceras.) From what I've heard of ATC speakers, they should be a very nice complement to the Luxman sound. I use Cardas Golden Presence speaker cables and they sound so nice with the Luxman (and my other amps) I've never had much interest in replacing them. I imagine Cardas interconnects would be a good place to start. I have to give TMR audio in Colorado a nod as a good place to shop for cables, especially used ones. They let you send back anything that isn't working for you and all you're out is shipping. 

I'll bite.

Reiterating Ralph Karsten's (atmasphere) opinions, your equipment should follow AES standards for Balanced operation (that you are using Luxman equipment, I 'think' you should be in the clear, but having no wiring diagrams, I couldn't say for sure.

That being said,

I bought a set of Mogami XLR cables from Ralph, when I bought his amps and preamps (tubes). I followed my favorite dealers recommendation and tried some AQ XLR cables (non DBS). To my ears, it, too, didn't yield a significant difference.

I will say,

I have used AQ cables for my system after I heard the William Tell speaker cables. They were truly mindblowing in the sound difference from my GO-4's. So, I think that if I were to move up the line to a 'higher' cable, I might be able to hear a difference in XLR cables.

Is that worth the cost?

I love my system as it is, and am in no hurry to spend more.
