I listened to it briefly. It definitely had some shout and sibilance to it, at least to my ears (I didnt hear any other opinions on it from the show floor). I know it's a prototype though, so if they sort the tuning it will be another nice option. The EE Ruby has a similar sound but left a...

I think this will be due to either driver size, orientation or contact with the shell, or a mixture of all three. There is so much variation in concha size and shape. When I see transparent CIEMs I am often amazed how companies fit drivers into those more challenging shapes. I agree though, a...

4EST is much better than 2 but I was just thinking about space in the shell and that we also don't really know how big this full range BC is. Either way, another interesting future release to track. I am more than satisfied with the Voltage so I will be a happy spectator for this one...probably.

Looking great. Shall we start guessing the driver config? I think either: 10BA + 4EST or going full quadbrid... 1DD + 1BC + 6BA + 4EST (or 2EST if they can't tetris in 4).

Looking good! I love these micro IEMs.

Given your time with the Traillii, you're probably in the best place to comment on how the Impact sets itself apart? There has always been inference that they are different but as yet, I don't think anyone has captured how in any great detail unless I missed it. Also, if you have already made...

I should have picked this up when you mentioned it to me. They aren't screw on, theres a little guide that ensures it fits a particular orientation. Hopefully that's still there if you've been screwing lol...

Thanks for this! I see now, so we're paying to ensure they're cables appropriately wired. Not sure I have use case for SE output at the moment. Concerto in low gain mode is reasonably quiet on the noise front except with the more sensitive BA sets <20ohm...

This is interesting... That cable just looks like a BAL --> SE adapter, yet the paperwork included with the Potenza says not to connect a converter to the BAL output as it will degrade the sound and put the circuitry at risk...

Is it the Sonion BC driver?

Your zero chance increases substantially if you're willing to drive to Hifonix in the West Midlands. They are the approved dealer from Aroma in the UK and have a Fei Wan to demo. However, @Kiats suggestion of a trip HK or Singapore sounds more appealing...!

Potenza top and Concerto bottom. Trying to put them head-to-head on harder to drive sets!

H40 is still a special listen to me. Very easy to listen to and not technically deficient. I also actually prefer it over the H50, it has much more character and musicality, ymmv.

I think for a lot of users it will be overkill but I'm sensitive to loss of dynamics, control and either end extension that tends to happen with higher impedance sets when underpowered. It's especially notable on smaller drivers like earbuds where they need that power to convey the low end even...

Yep, I'm hoping it will compliment the Concerto nicely.

I ended up purchasing the amp from @rufus0910 and he was a pleasure to deal with. FQL Blue Moon (130ohm Be) > Clan Audio BM OCC > Sound Tiger Concerto > Lotoo P6K The Concerto is a beautiful amp that really compliments the P6K sound, maintaining it's neutral signature but improving stage...

FQL BM > Clan Audio BM OCC > Sound Tiger Concerto > Pure Silver Viet IC > Lotoo P6K Beautiful combo for orchestral and opera. Massive stage with an open air amphitheatre-like sound that captures the delicacy and detail in voices.

Nice impressions as always! Tomorrow I will be saying goodbye to my VOLTAGE for a short UK tour. Although my free time has been in short supply as of late, the time I have spent with VOLTAGE has been superb. I have no desire to EQ as the 0-1 switch setting hits my preference in tonality and...

Beautiful photos highlighting the deep colours! This shell is excellent. Lightweight, contoured well (for my ears, atleast) and the nozzle is not too broad or long. Definitely taking inspiration from the Impact and by extension, the Traillii. Yet here we have a helpful vent to equalise...

Excellent buyer, quick payment, no issues!

Agree with all of these observations, including the last smidge of subbass being absent for total genre domination but with time this might become a non-issue. Even if it doesn't, it's still a no-brainer for a balanced and versatile IEM. There are very, very few shortcomings (bar the cable chin...

This shell is excellent for my ear shape too. The custom route would just be going for that last 1% fit and isolation.

PENON Voltage Impressions Tips: Whizzer SS Cable: stock Obsidian, 4.4mm modular termination Source: LP6K (neutral leaning source), high gain; FLAC 16 and 24bit Disclaimer: overnight burn in - I understand that much more is recommended (100-200hours) and so I imagine things will only mature and...

Penon VOLTAGE in the house. I will post some impressions tomorrow with a bit of burn-in but two big thumbs up so far! Edit: if I had three thumbs it would get that one too...

Smart looking set. Looking forward to hearing more on this one!
