老哥请问是直接用手机/电脑连u26+r30再接耳放的吗？我最这套配置挺感兴趣的

我是网桥连U26再用iis和同轴到R30，R30到耳放的，同轴平时听44.1，iis是玩升频的，我也试过用电脑连u26，效果也非常好，这套系统目前我觉得是玩r2r普通人的天花板了，除非你想去折腾那些更贵，如果你喜欢刺激点的声音可以考虑X30，还便宜几千块

大哥，大U鼠二代是给USB洗水的，可以串，但是U26是界面，没法串，虽然也可以说它洗水，但毕竟输出形态改 ...

才子，u26既然有洗水功能，那你拿它和audiobyte的超级哈勃对比听过没有？

Just would like to share my exeprience with DSD2048 from initial PGGB 9th order files to 15th order and then now the PGGB 25th order. It is no exaggeration to say that the SQ  has undergone 2 giant steps up. I can still remeber that 6 months ago when I first reported the success of playing DSD2048 files on Holo May through the Gustard U26 as DDC. I have been using DSD1024 for quite some time but the DSD2048 at that time 9th order still gave me a big surprise in terms if increse in detail and overall sense of being there. But some of my freineds when they come over to listen they found yes there is more details but the sound is a bit congested. Then there was PGGB 15th order. There was a little setback at that time not because of PGGB but only that I found out some crackling noise when I play DSD2048 for longer than 1 hour. With the help of some friends we finally ironed out the cause being the U26 was over heat and also the Holo May also has overheat problem with DSD2048. Some advise from experienced friends was to use an external clock for the U26 and this was spot on. There is no more overheat of U26 but there is still crackling noise from Holo May. Finally I used a cheap but effective method to lower the heat of Holo May. This is by raising it from platform for at least 5cm with whatever high foots or toes one can find. And this is further enhanced by adding a cheap USB charged battery operated fan with 16 degree C wind blwoing towards the Holo May and the Holo May is now cold as winter. And besides no crackling sound ther is no more congested sound but a relaxed and at ease sound comes out. this is the time when the PGGB 15th order is available and bravo this is a big big step up over the 9th order. When I thought theis is already the ceiling and there comes the Rob Reiner edition with DSD2048 25th order. I spent 36 hours to process my Fiddler on the roof broadway album to DSD 2048 25th order and I was really shocked by the result.  I literally sit there and listened to the whole album without stop. Can't help but being drawn into the music. The sound is super transparent now so much so that one can hear every detail you can dream of. There is sevearl layer of high frequnecy that one can hear. there is total coherence from low to high and phrases are just as smooth as one wish. Everyone is in its natural position singing or playing their parts. No need to guess. And above all there is a sense of ease and one is listening to real music. I also have a Taiko Olympus in my setup and I would say that for this album I would much prefer the PGGB DSD2048 25th order playing through my Taiko Extreme than playing the PCM 44.1 file through the Taiko Olympus.( Previously the Taiko Olympus playing PCM 44.1 is preferred). Big thanks to ZB for introducing this Rob Reiner edition. This is definitely the version to go for.

最新版本的 PGGB 再创高峰，目前可供选择的调制器分为 LN／VLN／ULN（低噪声／很低噪声／超低噪声）三大组别，ULN 对于内存方面的需求非常可观，因此只有 128G 的算力机就需要花费 36 小时才能够把 CD 格式的专辑（离线）升频为 DSD2048。

「等价交换」这种法则是永垂不朽的，且看 Olympus 与及 Extreme 两者之间的差距，前者的整套西装索价 EUR 89K，而后者的单机价格则只需 EUR 28K：

早前的测试版本只能够达到 VLN 的水平，播放 CD 格式的 Olympus 还是略胜一筹。

最近 ULN 面世之后，Extreme 播放 DSD2048 的时候就能够反超前。

（Olympus 只提供 Roon，加上用户无法安装其他软件，理论上仍然支持 DSD512，但 CD 格式的音质还是比较好。）

DSD2048 美中不足之处实在是有点麻烦，播放这种格式就会发现歌诗德 U26 和 Holo May 两者发热量真的感人，前者需要外接时钟，后者则需要借助 USB 供电风扇的力量，因此音质取决于散热方面的一点点功夫。

而且只有大编制的交响乐／音乐剧才能够尽显 ULN 的魅力所在，凡事也有一定针对性的，请勿把它当作万应灵丹。

算力机的成本方面也是十分蛋疼，供不应求的 DRAM／NAND，内存的涨价，超贵的固态盘，还有全球能源危机。
