Thank you very much for the detailed comparison. I am torn because I’ve been lusting for the LCDi4 before I settled on the iSine 20. Trying to rationalize spending 4.16X for the TOTL.

@OldDude04 why you want to sell? You found another amp to love?

I've been loving my iSine 20. But...I've been curious about the LCDi4. How much better can the Audeze in-ear headphone sound get for $2495?

The flat cable is the original V1. The newer cable V2 is like a normal cable (rounded).

The iSine 20 with EQ powered by iFi micro - iDSD Black Label and XBass+ switched on is

You are not wrong. The iSine 20 with EQ powered by iFi micro - iDSD Black Label and XBass+ switched on is Instead of going naked, try this: https://www.audeze.com/products/accessories/lcdi4-premium-braided-cable

50% is my usual on the iPhone X with the Sine+Cipher. Sometimes up or down 1-2 bars depending on the song.

Yes I agree with that but my sense of humor got in the way

Well, isn't $125 cheaper than $150?

Travel case for LCD2/3/X/XC/MX4 $125

+1 on the on-ear experience. When I first got the Sine I tucked my ears into the pads and I really liked the sound. When I just put the Sine "On-Ear" as intended, it sounded better and I do not have any comfort issues.

I don't get brightness with my Sine, but Tyll did and he used this EQ:

I'll try that when I get an EL-8 Titanium. But for now Daft Punk is Doin' It Right on my Audeze Sine

Yeah that's basically what I used for my Sine, except I cut 8kHz 1dB and 16 kHz 2dB
