I will PM you what I am using on the Solaris. Solaris is a bit picky on the type of cable it likes.

Leo plus or OSG is the question...

@Dsnuts thanks for the review. What do you recommend for Solaris over the CA super litz? Thanks.

Hi
I went on a cable buying frenzy and bought 8 cables
1. OSG
2. Leo plus
3. GD849
4. Dunu blanche
5. Effect audio ares 2 8 core
6. Oc studio monarch
7. Oc studio caelus pure copper
8. CS819

I have 7 iem
1. Noble encore brass
2. Noble tux5
3. Noble k10
4. Empire ears zeus
5. um mest
6. Jh audio Diana
7. IE800

Player:
SP2000

Let me put it as simply as possible the leo plus is the best sounding cable I have ever heard, nothing like osg, it's 100 better in my opinion then osg, the osg adds brithness which I don't like but the leo is perfect. The stage is enormous

I'm actually going to buy another leo plus

@EdgarBear
I Bought OSG and i like it vey much with IMR Opus Mia, maybe because isn't too bright especially on mids with stock cable.
I'd like to listen Leo Plus because i was going to buy it than i chose OSG reading feedback.

How does the Leo plus behave with low frequencies? Is there any cut, are they maintained, or is there some kind of improvement? Thanks!

I use it on my IER Z1R. It maintains very good definition for bass. Is not like a pure silver cable where it can lean out the bass end. I still get the full bass end of the Z1R. Excellent for bass actually.

Did bass gain a better control and speed? I have Shuoer EJ07m IEM, it has a slight bass lift but bass itself to me lacks some speed and impact a bit, it is sort of more bloomy a bloaty to me. So looking for something that can slightly give it more balance, control and impact. Now I am using the original silver plated copper cable, also IEM is almost new maybe some burning in will sort some things out.

Leo plus foundation is pure silver so it will add some definition to the bass end your earphones. This being said you most definitely need to burn in your earphone and see how it shapes up. Bass should tighten up.

Great, thanks! Great review, will consider the cable!

To bad that it doesn't have modular jacks, have Dethonray DTR1+ Prelude DAP which has a powerful 3.5 mm output, so need to buy then a cable with 3.5 mm jack instead of 4.4 mm balanced which makes it less future proof and harder to sell. Perhaps need to buy 4.4 mm and adapt it in some way, there are also conversion kits so you can make your cable modular.

By the way did you find that your IEMs became brighter with this cable? Did it affect tonality in any way?

Not really. I am currently using it on the Sony IER-Z1R and used it on the Ibasso IT07; Both having full end trebles. Does not accentuate trebles but more highlight details for the trebles. On the opposite end it does not lean out the bass presentation of earphones either like pure silver does for earphones at times. Leo Plus enhances sound separation, stage imaging and detail for earphones, one of the best at what it does. I like that it does not shift an earphones tonality to be something it isn't. Which makes it versatile. It is very transparent like that.

Thanks for your response. So you don't fell like you are missing some of copper aspects? Well it sounds that it has a great balance, those extra metals do balance silver out and no need to have copper for more balance. Having my eyes on other similar cables with copper involved as well, some even have graphene involved additionally but the reviews are mixed, some highlight low end, some reduce upper treble energy, this one for example https://www.aliexpress.com/item/1005003527657190.html. Anyway it is great to hear that this cable keeps tonality more or less intact.

What earphone are you looking into a cable for? ISN just came out with a new G4 which is a new graphene and copper based cable.. ISN is Penons sub brand so made by the same folks that did the Leo plus. I just did a review for. If you want something to thicken the sound and enhance bass to mids and stage with a smoothening of the trebles the new G4 does that with a nice uptick in imaging due to the graphene. https://www.head-fi.org/showcase/isn-g4-iem-cables.25670/ If you want highly transparent cable the Leo Plus is a different level of cable.

It will be more of how the host earphone synergizes with the cable.

I have Shuoer EJ07m, it is great but have some cons for me, the treble is to smooth and there is lack of energy in higher frequencies, I am used to brighter IEMs so I sent my IEM for retuning for additional price, so they would elevate treble for me +4 dB in certain frequency range. Also soundstage of EJ07m is holographic but vocals themselves sound in front of you, feels like that there is lack of some air for vocals themselves, no problems with instruments, so I found that raising treble also moves vocals further away from you adds some space. Another con is boosted bass which I found is not quick enough for me and sort of lacks of some control. But as I said it has holographic staging, imaging is top notch and vocals sound amazing so I thought I could improve it in some ways and have best of both worlds. So what I expect form cable is better soundstage and tamed low end with more control which points me to silver.

You did good in looking into the Leo plus. I would try the Leo plus. It seems like that is what your looking for. If anything it is the one cable you can always use on other IEMs. I would go for it.

Want to torture you a little bit more . Did you notice any changes in vocal performance? Usually when there is gold involved vocals sound smoother and sweeter, did you notice any of this? And sound in overal, did it become more natural in any way especially on hibrids? What about BA timbre?

Leo plus does not have enough gold in it to change tonality for mids at all. It is like an enhanced silver properties vs being influenced by gold. Very transparent cable but at the same time does not make your earphone to sound like something it wasn't meant to be. If you have warmth to your mids it will have warmth to the mids for example but what it does is hones down on imaging properties, detail and enhances dimensional character and stage for earphones. I use it on my IER-Z1R. I have had zero need to use anything else. I have never used the stock cable as I know it will be inferior. I love the fact that it does not lean out a sound like some silver cables do as well. I have cables that cost 4x as much and I consider the Leo plus to be one of the best cables I have and reviewed.

Thank you! No more questions.
