Hello to everyone at the Watercooler!! I want to post some impressions of portable amps that I tried at a Korean portable audiophile community's local meeting held a few days ago. It was a great opportunity for me to try some greatly regarded DAPs, cables, and amps.

I have been mainly listening to headphones on a desktop system until recently, and I had thought that the amps were only necessary for full sized headphones. However, after recently purchasing some DAPs/IEMs for portable listening, I naturally became interested in portable amps. But the prices of well regarded portable amps are very high, so it is very burdensome to buy new or even used ones. So I haven't had a chance to try high-end portable amps. The main purpose of attending this meeting was to try some portable amps with my recently acquired DAPs (Astell & Kern SP3000, HiBy RS8) and IEMs (Unique Melody Multiverse Mentor, Campfire Audio Trifecta).

The first amp that I tried was Mass Kobo 428. It was the best fit for my personal taste. I liked the vast staging and rich boosting of low bass and it felt like a slightly warm toned amp. The matching with SP3000 was more balanced than RS8, IMHO. RS8 with Mass Kobo 428 felt a little too bloated in the lower frequencies. Because of my preference for warm tones, it was the best amp that I tried at this meeting.
The second amp that I tried was Brise Audio Tsuranagi. As I read prior in the reviews of Tsuranagi, it felt like only boosting the raw performance of original source. The detail, resolution, staging, output was greatly improved, without altering the original sound signature. In the case of Tsuranagi, I liked the matching with RS8 more than SP3000. When using with SP3000, the highs and treble were too strong to my ears. After changing the 4.4 balanced
silver plated pure copper cable (Brise Audio IZANAGI) to a custom made gold-copper alloy cable, the harsh treble got tamed a bit, but... Still, I felt that the balance with RS8 was better.
The last amp that I tried was Phatlab Phantasy II. I felt that the absolute performance (resolution, detail, staging) was somewhat inferior to the two amplifiers that I heard earlier. However, the tone itself was very pleasant with adequately boosted lows and smooth mid/upper frequencies. Maybe this pleasant tone was due to the triode inside Phantasy II.
To sum up, I had a great time with some friendly folks and brilliant gears/amps that day. This local meeting had changed my mind that portable amps have great and positive impact to the sound qualities of portable DAPs and IEMs.
I might get a chance to try the newly released Enleum HPA-23RM, in sometime this month. I will try to post some impressions, if possible.
Lastly, I want to wish a HAPPY NEW YEAR to everyone at the Watercooler
