| 300b lovers Of course, it is tempting to design a special-purpose headphone amp. I own HifiMan HE1000 Stealth (V3) planar headphones myself, and I use a modest all-in-one DAC/headphone amp to power them. But ... the headphone amp market is quite crowded, and... | |
| 300b lovers In terms of load abuse, plugging planar headphones (20 ohm to 32 ohms) into the Raven preamp will definitely load down the preamp and is not recommended. No harm will result, but the preamp will slide over into Class AB operation and distortion wi... | |
| 300b lovers The Raven is not very sensitive to loads. In practice, power amps range from 10K (typical solid-state) to as high as 470K for a handful of vintage tube amps. Most modern tube amps are 100K. Plus whatever cable capacitance is there, along with the ... | |
| 300b lovers I fully defer to Don, who is part of the loop of the Spatial team, who manufacture the preamp and power amp. I’m more like the system architect, guiding the project in a certain direction, and I’m not as aware of the manufacturing and production s... | |
| 300b lovers To the best of my knowledge, the price of the preamp is $5000. Possibly less when purchased as a bundle with the power amps. The XLR output should be AES compliant, driving both phase equally. | |
| 300b lovers I got into the amp game after auditioning both the Audio Note Ongaku and the Reichert Silver 300B on speakers of my own design. I’ve been designing speakers since 1975, so I have a pretty good idea what goes in them and why they sound the way they... | |
| 300b lovers Yes, I've come to the conclusion that speakers and power amps are about 50/50 responsible for overall sonics. Based on measurements, you'd think that speakers are responsible for 90% of system coloration, but in practice, no. The amps have a big r... | |
| 300b lovers If Spatial is at the Seattle show this year, yes, I will be there. I had a lot of personal stuff that precluded my attendance at Dallas, but it sounds like the SWAF was great experience and a good time for all. Don tells me there is a lot of seri... | |
| 300b lovers Spatial Audio at the Southwest Audio Festival, with the new Q3 dual 15" dipole speakers and the latest Revelation Series Raven preamp and Blackbird power amps. The pint-sized Mola Mola Tambaqui DAC is tucked behind the Raven preamp. | |
| 300b lovers Official Web page of the Revelation Series: Revelation Series at Spatial Audio | |
| 300b lovers Still making small production changes to the Revelation Series power amps and preamps. The main B+ power supply choke (filter) is now from Monolith Transformers and is on top of the chassis, along with the output transformer and the power transf... | |
| 300b lovers Spatial Audio now has the preamp and power amp in production (scroll down about halfway). The power amps are now 18" wide, the same as the matching preamp. The tube lineup is 6SN7 input (balanced), triode-connected KT88 drivers, and 300B output i... | |
| 300b lovers I did most of those things for the Seattle trip. I hadn’t flown in more than a decade, and I knew it would be Hell on Earth if I didn’t tick all the boxes. So, in the months preceding, I applied for TSA Pre-Check, Instant Bag Check using the QR co... | |
| 300b lovers Don and the Spatial team will be in Dallas, but I will be home here in Colorado. If Spatial goes to the Seattle show this year, I will be there along with Don. I learned my lesson about flying last year. This time, I’ll fly First or Business Clas... | |
| 300b lovers Maybe Peregrine. Something fast and powerful, which are the hallmarks of these designs. |
