Went back to the Meze booth to compare the Rai Penta to the Solaris. To put things in perspective for my comparison, I used an A&K SR15, stock cables for both the Rai Penta and Solaris, and the same silicon tips on both IEMs (got them at Meze, T400, and they fit me very well). I listened a combination of Tidal regular and MQA files; and some 24/192 files.
Both IEMs are great and I think anyone would be happy with them. However, they are some differences from both an ergonomic perspective and a sound perspective.
Ergonomically, the Rai Penta is the better of the two. The fit for my ears is great and very easy to get in / out of my ears and I don’t need to move them, etc. after the initial insertion. They are a lot smaller than the Solaris, and fit almost fully in my ear. Enough so that I think could sleep in then on my side - perfect for long haul flights. As everyone knows, the Solaris is a fair size IEM and on my they do stick out a good amount. Fortunately between the tips and the memory wire on the stock cable, once I get them set properly, they are good to go and I don’t need to fidget with them.
On to sound, the Penta has a more neutral signature as compared to the Solaris, but there is bass and you know it’s there. However, the sub-bass that I get with the Solaris isn’t there. There are some songs I listen to that I can “feel the bass” on the Solaris, but not to the same level with the Pentas. “Unstatic” by Manu Katchè is a great illustration of this. There’s also a slight difference in the highs. The highs are more separated on the Solaris. With the Solaris I can easily discern cymbals in a track while drums are being struck. While I can here that on the Penta, it’s easier to hear on the Solaris. The track I used here is the live version of “In the Air Tonight” by Phil Collins on Face Value (Deluxe). Another good example of is “Lunatic Fringe” by Red Rider, at the 24 second mark, there’s a back ground vocal of “See you on the other side.” It’s very discernible on the Solaris. While I can hear it on the Penta, it’s not as clear. The other key difference is the soundstage. The Solaris has a greater soundstage over the Penta, it’s a small difference, but still noticeable to me.
I think the Penta is a great IEM, the Solaris is just better. For home use, the Solaris is my choir of the two since I have time to get the fit correct and don’t plan on sleeping on a plane with them. For travel and out and about, I would choose the Penta, since I can easily insert them, there’s no fiddling with adjusting, and they are smaller - fitting fully in my ears so that I could even sleep with them in. As a side note, I tried the new Westone UM50, specifically with travel and sleeping on a plane in mind. The next CanJam I attend I’ll spend more time with the UM50 to compare it to the Penta. I’ll stress here that one of my key requirements is size, sound isolation and the ability to use a bluetooth cable - pure audiophile specs take a backseat since I’m in a noise plane at altitude.
Had a great conversation with
@ag18 outside the Meze room on this topic. I know he bought the Pentas and it would be good to hear his thoughts, especially after using them and since he has CIEMs.
Would I buy the Penta, yes. Would I buy the Solaris, I did at CanJam NYC.
Hope this helps.
