| 300b lovers @alexberger Congratulations! Lovely amplifier and you should be proud. I hope it brings you many years of pleasure, until the bug hits to try yet a different circuit:) I assure you, the addiction never ends! | |
| 300b lovers I have done every permutation and combination of ways to build this 300 PP circuit. I originally started with high quality CCS and then went to LC coupling, which sounded more natural and musical to my ear, and then finally went to full transform... | |
| 300b lovers That is the first thing you notice when you hear our 300b PP. The bass is amazing. It is not over emphasized at all, but if there is bass energy on the recording you hear it all. Most importantly, it is the quality of the bass, not the quantity. W... | |
| 300b lovers @audioquest4life I did not make it to the room you mentioned above. I was quite busy running our room with Spatial Audio Lab and only made it to about half the rooms at the show. The link you posted did not work. Can you check and repost it? | |
| 300b lovers We just did the sw audio fest in Dallas using the original version and we had one of the top rooms at the show. It really isn't a big change. | |
| 300b lovers @fthompson251 Hi. It is a very subtle change that I find inaudible, but on paper it is slightly better. The xlr inputs now go directly to the Attenuator and the rca go through a 1:1 transformer to convert to xlr. The previous version ran all... | |
| 300b lovers I believe the preamp is $5500. Search for spatial audio lab, find the site and look at the revelation series and preamp and you will find it. On the preamp, it is fully balanced and transformer coupled to output. Pin 1 is shield and grounded to... | |
| 300b lovers I just returned from Dallas, and I have to tell you that our room was one of the top two or three in the show. Danny Ritchie (GR Research) came by and told us our room was his pick for best sound of the show. Sam Whitt, the speaker designer at S... | |
| 300b lovers No, not that I know of. Dallas, and then I think they are planning on going to Seattle again in early Sept. You should write them to see if they are planning on going to the east somewhere. You can contact them via their site. | |
| 300b lovers Just a note that Spatial will be at the SW Audio Fest in Dallas, March 15-17. They will have the final production versions of the Raven preamp and Blackbird mono 300b amps driving their speakers. I will be there all day Friday and Saturday, and... | |
| 300b lovers Well, they are really fast:) | |
| 300b lovers @downtheline Actually, next up is a two stage amp with another lovely DHT in push pull for a whopping 3-4 watts at very low distortion. Not a 300b so not for this thread! You could hang a custom transformer off it for phones. You would want a R... | |
| 300b lovers @downtheline The Raven has a headphone jack, yes, but as Lynn noted, it will only drive the typical old style phones. It will not drive planars. Sounds great with my old Sennheisers and phones of that type with 300 ohm impedance. | |
| 300b lovers ... Actually, sonically the statements and the Blackbirds have similar heritage, but the Blackbirds are much better. The Monolith Magnetics iron is just sublime, plus the power supply is improved in several ways including the addition of the pai... | |
| Linlai KT88 experience? The Linlai WE 300b exact western electric copy is in my amps. We used them at the Pacific Audio Fest. They are wonderful and I stopped looking at 300b options when I got them. There may be better 300b tubes out there, but I really don't need to... |
