This was put together at very short notice. Thanks to @uniqusrname,@Arun Kumar and @Thad E Ginathom for coming. At the previous meet in January, we agreed to meet if there was "enough" new equipment to listen to. Hence for this meet, @uniqusrname brought a DIY Sapphire solid-state amp (he made it for me), his modded ADCOM GDA 700 DAC, a GOV2 Infinity DAC/amp, an Allo Digi-One streamer, and for HPs, he brought his recently acquired HD 800S, a Senn HD 540 Reference and the Symphones Magnum v4. Arun had his modded HE 560 (with Jergpads) and his HD 600. I had the RME ADI-2 DAC, the Gungnir Multibit with Eitr, the Jotunheim (amp only), the BW (with separate PSU), the Project Ember and a bunch of HPs - the LCD2C, HE-6 (this was an act of futility for obvious reasons), the LFF Slants, the Creative Aurvana Live modded by SBAF member @gurubhai, the Senns HD 600 (stock), the 650 and 800 (both modded). The objectives were primarily to listen/compare the Sapphire, the BW and the Jotunheim with the various HPs, and to evaluate the DACs (especially the RME, as a DAC and an AIO). In addition, we were listening to the HD800s, the HD 540 and the Magnum for the first time. In terms of music, we had our MacBook laptops and soon decided on Fleetwood Mac rumors and Dire Straits Love over Gold as the reference albums. My brief impressions are as follows: The Sapphire easily stole the show. @uniqusrname had brough an earlier version to the January meet. I was interested enough to ask him to build me one. This version was much more linear with very good extension on both ends. It is a neutral amp with great clarity, does not add any color, and hits hard with ample sub-bass. I will let him describe the technical details. It paired very well with all 3 DACs and had very good synergy with the Senns (more with the 800S relative to the 800), the Slants and indeed the rest of the HPs. The Magnum did sound Beyerish though. It was a very interesting comparison with the BW. There is absolutely little to separate the two. The BW does have a little more warmth and is bit more veiled. It has good synergy with the above HPs, especially the 800 (as opposed to the 800S). Even the Magnums were more tolerable on the BW compared to the Sapphire. The Jot did well with the planars and the HD 650. I did not like it with the 600, 800 and the 800S, or the HD 540 and Magnums. I've already offered my impressions of the RME in its thread. Nothing more to add. It is a superb value not only as a DAC but also as an AIO. Yes, the amp is a bit of a let-down compared to the amps we had for impact. As a DAC, it continues to impress and the guys all had the same question after first listen " Is this really delta-sigma?" I hear the stock HD 800S for the first time. Its low end and warmth (compared to the 800) were obvious as was the slightly smaller head stage. This HP had its dust covers on so dunno.... I can see this being preferred by some to the 800 (even modded). Finally, I'm posting pictures of the meet including the awesome lunch we had (I'm looking at you @jexby). And a wave to @FlySweep .....our home city has now had two meets after several years of none!!
