Do you mean Yes? I can't find any reference to a King Crimson song of that title. (Off topic, but Yes finally made it to the Rock & Roll Hall of Fame. Will justice ever be done for Mountain, Jethro Tull, and especially Warren Zevon? When you look at the lengthy list of talentless hacks in the HoF, their exclusion is embarrassing.)

So I noticed that the Massdrop LCX amp is active and is cheaper than the THX 789 at $299 vs $349. https://www.massdrop.com/buy/massdrop-x-alex-cavalli-liquid-carbon-x-amp

I also noticed this same amp is being sold used here. https://www.canuckaudiomart.com/details/649488364-massdrop-cavalli-liquid-carbon-x-lcx-amplifier/

Is it better to wait for the THX 789 to drop again or grab the LCX amp? Either one would be paired with my Grace SDAC and used with balanced out once my Periapt XLR cable comes in.

I had the same question at one point.. Was told wait for the THX.. Because it competes with more expensive amps.. Glad I waited for it.. Because it's great. But I dont think the next drop will be for awhile.. So you would have a longer wait than I did.

I do have an Aune X7S right now which does very well. I'd say my only gripe with the X7S is the rear power switch and the gain switch on the bottom. I'd rather both on the front panel. I don't mind waiting but yeah it seems like I'll be waiting a while.

Thanks for the links. I will check those out. I don't really know what the info in the graphs and charts mean though.
A whole lot of stuff that is audible--maybe--only to bats.

Hehe fair enough. I don't hear any distortion or hissing or whatnot with my X7S so I imagine I won't hear any with the THX 789 either. To me the X7S is clean sounding. Guess I'm just venturing down the "rabbit hole" of audio.

Maybe you stated this earlier...but is there a reason you are using XLR cables with the SDAC? It has RCA outs right?

If that is the case, using an RCA > XLR cable would not give you a balanced signal, and would offer no advantage to just RCA > RCA in your audio path.

Or are you talking about a different cable?

Sorry just trying to understand.

I will be using a balanced XLR headphone cable for my HD6XX. The SDAC doesn't have balanced output on the back and my Aune X7S does not have balanced input. But it does have a "balanced" headphone output as does the THX 789. Not sure why my explanations are confusing for people.

I was confused when you mentioned an XLR connection right after SDAC. Sorry, my mistake.
