Hi, new RikuBuds owner here. Im quite new to the world of earbuds but not to Head-Fi in general. I recently got my hands om a pair of Penon PAC (who sadly broke after a week) and was quite impressed by sound and comfort. I did some reading and ended up ordering a pair of Grand Alter Saber 3 from RikudouGoku.
First impressions were that these buds play at a completly different level! After a while of listening i can confirm my first impressions, GAS 3 is a masterpiece. They sound good from Go Blu but a little better from Gryphon. They take XBassII really well without bleeding. The soundstage is great and voices sound so nice. I am most impressed by the technical level across the register. Organic, too, with adequate separation (not to much like some IEMs & planars). The base really has a lot of texture. Sure, it's not a basehead bud, but it's nimble, fast and with a lot of detail. I assume that it takes EQ well as XBass works so well. Then they have a slightly restrained mid-bass, but that's also what brings out voices so nicely. Then the detail and "sparkle" at the top are great too! And the soundstage is wide and holografic coming from such a small little bud.
Ive had some pretty impressive open-backs over the years and i can really say that GAS 3 can replace most of them at a fraction of their price. If you like i do, prefer bass boosted neutral (i think it handle most genres excellent) GAS 3 delivers true head-fi in a super portable and comfortable package!
I am very pleased right now and I clearly prefer them to the IE600 and that says something. Well done!
