I mean if the difference is the volume control and the dimmable display….

Did some digging and this is what I found:

The newly updated EX-M1 includes, among other things, changes in the power supply, capacitance, and the volume control, the latter now using a MUSES72320 controller instead of the previous relay-based control.

The M1+ has preout which would be nice if I ever wanted to add a sub…

On the back, seems the newer model has a DC filtering switch, a ground and earth plug and a switch that says link or float? Unsure how these may all affect the sound…

@Ghost did you buy yours new? Assuming yours is the newer model?

DC filtering will filter out DC pollution on the AC current which can cause transformer hum. Link or float is to do with chassis grounding I think. When it’s on float it doesn’t chassis grounding and when it’s on link it does. Gives you options with ground loop hum.

I bought it used, but ended up getting a later generation M1. I have the link/float and all that!

I hope this question is ok here bc I didn’t see a thread dedicated to technical questions.

What (if anything) would happen if I connected two sets of cables to the balanced and unbalanced lines out from my CD player? Currently, for regular listening, the CD player connects to integrated amp with balanced connection. The CD player also has a set of RCA outs.

I have a new use-case involving a pre-recorded radio show, and, for the show, I want to be able to record music from the cd player onto my computer. I have an audio interface with line-level inputs and DAW software for this purpose.

Importantly, the back side of my system is not easy to access, so I cannot regularly switch out cables. In other words, I cannot unplug the balanced connection every time I want to connect the CD player to the audio interface. Instead, I’m hoping to use the RCA outs on the CD player for this purpose.

In that scenario, the CD player would have cables plugged into the balanced and RCA outs. I’d connect the RCAs to the audio interface when recording and power down the integrated so that there will always be only one active connection from the CD player. Will that work or will the fact of two connected outs from the CD player affect the signal from the CD player into the audio interface?

If it helps, I think a simpler way to approach the same question would be to eliminate the radio show use-case and imagine that I wanted to connect the CD player to two different amps, with one powered down at all times.

Would appreciate confirmation (or not) that I think I found a solution to this problem that avoids even theoretical problems w CD player and actually kills two birds with one stone bc I’m also recording vinyl from my turntable. I didn’t mention the tt yesterday bc the lone exception to my challenges changing cables is the Darlington phono-pre, which is accessible and easy for me to pull the line out to integrated and replace it w cable to the audio interface.

But I think the solution circled below avoids all of that . . . A line-level out from the integrated itself that should be fixed volume (not affected by integrated volume control). Bc the audio interface has its own gain stage (incl LEDs that show gain/clip levels), my understanding is that, if Ieave a set of RCAs plugged into the integrated’s line out, I can plug them into the audio interface whenever I want to record the source selected on the integrated. Is that right? Sorry for noob-ish questions. This is new territory for me.

I think the line out from the integrated is a good solution. However, I would not leave the RCA connected to the line out on the integrated without a receiving load on the other end unless you can disable the line out signal when not in use.

Check out the EX-M1+ review. It discusses the OpAmp rolling capabilities of the amp as well as the quality of the preamp section.

I have a couple of Sparkos OpAmps in my J2S DAC. I may pick up a couple of more and try them out in my Kinki amp.

I think I heard that you can roll the OpAmps in the M1! Maybe I was wrong, that feels so technical to me though hahaha.

What does that even do?

You can roll the OpAmps in the M1. The OpAmps are part of the sound output. They’re in DACs and Amps.

Rolling the OpAmps allows you to use a higher quality part in the output stage which allows you to tweak the sound of the device. I think of it as the solid state amp equivalent of tube rolling.

I think the stock Kinki amp sounds excellent, if rolling the OpAmp can make it even better I’m definitely game to give it a try.
 
Question…. Those two systems and some of them around here have the turntables at like knee height…. Is there a benefit to this? I fucking love having my turntable at chest height. My knees hate the bottom shelves and those/youse guys are like living there. (Also, is this why so many of you hate 45 pressings… lol)

I think it really just comes down to the general height of most media cabinets. They're all about knee height.

I had my TT low like that for a minute. It looks cool, but I didn’t like it. It now sits on a shelf about waste high. Less bending.
