I'm creating a second post to share some quick feelings about my latest purchases to pair with the i4.
It's been about a little week since I received the AMP3 card module for the iBasso DX 200 as well as a Billow 4 braids 2.5mm TRRS Beat Audio cable. Yes... I know... I was kinda complaining a while ago about the i4 not having a balanced cable and not wanting to spend $500 more for a cable... Well, you know what happened next,right?! I spent almost $2000 for cable, and the 8 braids version was even more expensive than the i4...
I know that's close to insanity level, but oh boy!! I don't regret a second my purchase! I remember saying here that the i4 sounded already great from my iPhone SE and not hearing a huge difference while jumping to the DX200 in single ended with AMP1, and it's true! They're already absolutely stunning!
But now jumping to AMP3 balanced with Billow cable that's another story, trust me! I can't believe the i4 could improve that much further. The detail retrieval, staging, separation and precision tremendously improved. In one word, astounding! I now understand the comments from people stating the i4 seriously scaling with good amplification!
I did a quick test comparing the i4 on the DX200 AMP3 + Billow against the iSine 20 with cipher on my iPhone. While listening to the track Tight Trite Night from Andy McKee with Don Ross, this was a really day and night difference! On the iSine 20 the two guitares felt little mushy in comparison. They kind of merged together, while with the i4 setup everything was crystal clear transparent with absurd staging, precision and separation. A whole new level in my opinion! And the iSine 20 are no slouch to say the least.
I still need more time to tinker with my new setup, because I believe the burn in isn't over yet and the sound might still evolve, and I'm still waiting for my 2.5 TRRS to 3.5 TRS adapter to try figuring out in which proportion the Amp and the cable improve the sound. I don't have other balanced cables that fit the i4.
I remember trying in a shop a $200 balanced cable with my AMP1 and didn't find much difference with the stock cable in SE. Here when I listened through AMP 1 with Billow the difference was clearly obvious. And now through AMP3 that's end game level to me.
Many folks around here seem to be thrilled with the Hugo 2 pairing. I didn't have the opportunity to try it out yet but I'd really be interested to see the difference! I'm not interested in buying a H2 because I don't want to bother stacking devices, but out of curiosity that would be a nice experience indeed.
Also, I had the opportunity to try very briefly the Tsar and Fourte for about 10min each, and while both absolutely great iems, i just find that I'm preferring the i4 by quite a margin. Let's say that both 64Audios don't bring much more to TOTL iems. Don't get me wrong! They are fantastic! But they are just iems... i4 aren't in iem's playground i feel.
I'll try to post some pictures and further thoughts after full burn-in.
Hope this can be helpful to some of you!
Cheers
