Previously sun had tascam DR-100MKIII, but many people still have a lot of Dafa plots, saying that it is not worthy of Dafa D100, because Dafa D100 is already old for some years, digital products should be bought new I bought it old, but I don’t know when I was awake. In fact, I’m not too excited about Dafa products. I’ve found a photo library and discovered that I’ve actually had a Dafa product in the past few years, but it didn’t surprise me. After six months, it has disappeared from my side, but it can still record its pictures. Yes, it is the old figure of the new sun: SONY PHA-1, its realization in the sony has been out 1,2,3 , 1A, 2A, 1 is also discontinued, you can see the link of Jingdong, description map for pha-1 has been off the shelf, but this does not affect my drying sheet, I continue :) Pha-1 looks like it was released in 2012 or 2013. At that time, the price was 3,500+. Indeed, its binding can make the iPhone at that time possible, and it may produce a qualitative leap, but at that time I bought it and it was intended to make it. And bundled with the Olympus LS-14 recording pen, sometimes bundled with the iPhone, after all, this kind of binding looks good, quite like C4 bomb or something. So it's time to start. Pha-1 has really made iPhone's thrust a qualitative leap by its bundling, but when it comes to qualitative changes, the ear was not able to hear the difference. At that time, other headphones were not in this office. Therefore, the AKG 242hd was mainly used. Come to the next. Stopped by some lossless songs, I feel mellow and mellow on the vocal, and the three-band convergence is not ideal. It may have some relationship with the headphones, but in fact there was AKG Q701 at the time, but This well-recognized but unreliable headphone, with such a combination, still does not allow the sound to have a rhythm to let go, or is it a bit restrained. But I still have to say, I still used nuclear power at the time. Pha-1 also has a problem, that is, battery life, after the volume level is turned on in the middle, it can support about 6 hours of playback, the battery is exhausted, but also used as a computer DAC, this time can not use the battery Power, powered by USB, but I said in the previous article, for this built-in battery, always feel that after they used it for a long time, the battery's aging and power-down speed will become a tasteless, this does not exist to say what brand The problem, but the built-in battery is an inevitable problem. Appearance, the design of the product to see at that time is indeed very handsome, compared to a loss of domestic ear tiles or amp, a lot stronger, zinc alloy die-casting frame, aluminum alloy shell, forcing very. There are ipod / iphone / ipad interface, and gain gain switch, finishing is still good, some product exquisite design details. But how do you say that, this gain gain, or can not move the headset impedance of 600 ohms. Too hard. The knob damping feels good and the rotation is still quite comfortable. The overall appearance was very high at that time. Back to the present, all three generations have now come out, and the prices have become more violent. It's not that Dafa's things are not good and they're good, but I'm still not that unreasonable, especially after I bought this Pha- 1, it did not give me so many surprises, therefore, it is just because of the binding and forcing one of the reasons I relatively accepted. Last but also added, in the case of the computer usb dac and amp, it supports 24bit 96khz, after I added my own dac and big amp equipment, the support is 24bit192khz, this difference is still a bit obvious I feel like I'm still suitable for wearing headphones. After you wear it, teammates will understand it. Finally, the new generation of pha-3's various parameters is really big, and it also has three gold chrysanthemum sockets.
