| DIY Pass Labs First Watt F5 amp impressions I think the XA25 is similar to the F7 but with balanced supersymmetry circuits. It's no more powerful than the F5 or F7 though. I've head that it's noticably better too. Of course you're going to pay a lot more for an XA25 than an F7. I think I re... | |
| DIY Pass Labs First Watt F5 amp impressions It's also worth pointing out that all the FW amps drive speakers in different ways. I chose to build the F5 because it's a "conventional" voltage source amp with voltage gain. Not all of the FW amps are. Many are current source and some are just s... | |
| DIY Pass Labs First Watt F5 amp impressions Seeing as how Nelson only constructed 100 examples of the F5 9-10 years ago they're probably as rare as hens teeth these days. The F7 is supposed to be an improved revision of the F5. Never heard one though. If one is of the DIY mindset and has a ... | |
| DIY Pass Labs First Watt F5 amp impressions Yep! And then doing everything he can to get guys like me to build them!More people should give it a try. It's like they say: the best amp you'll ever hear is the one you built! There's a lot of upsides to it though. You can't buy amps like that, ... | |
| DIY Pass Labs First Watt F5 amp impressions I'm totally loving the thing. The thing runs blazing hot. I'm running about 2.2 amp of bias through it and it idles at 55C on the sinks and about 77.5C on the MOSFETs. Maybe I could eek more out of it, but 2.2 amp of bias on rails that actually me... | |
| What does a bad tweeter sound like? I'm not familiar with those speakers, but if the crossover isn't a real bitch to remove checking those caps out wouldn't be a bad idea. I doubt you have a leakage tester, but all the caps should measure up into the megaohms on a resistance test af... | |
| DIY Pass Labs First Watt F5 amp impressions Thank you very much! It does have a brightness to it, but it almost seems like it’s just that much more clear and detailed up high than I’m used to which may be why it sticks out. There aren’t any negative characteristics of the highs except that ... | |
| Focal Aria 936 vs 926 bass response The 936’s need no subs to dig down to 32Hz quite flatly with some considered boundary reinforcement. They make just as much deep bass as the 948’s and are simply better suited for a smaller room. The thing with the 936’s is that they will reveal t... | |
| What does a bad tweeter sound like? I've had crossover caps start leaking real bad and it sounded very much like the driver was blown, but only at very specific frequencies. It was also slightly louder. I was dealing with an AMT though. | |
| Focal Aria 936 vs 926 bass response The 936's don't require obscenely muscular amps to drive them, just an amp that can drive a low impedance load. I'm currently listening to my 936's powered with a Nelson Pass F5 clone biased up to around 36 watts RMS class A and it's driving them ... | |
| DIY Pass Labs First Watt F5 amp impressions I'm listening to the amp as a write this and it sounds incredible! Very visceral, physical, deep, and richly textured sound indeed! It still needs a bunch of time burning in and to have the bias adjusted up a bit more, but I love the thing already. | |
| DIY Pass Labs First Watt F5 amp impressions The bias is going to have to be something I play by ear on account of the 32V rails. I've got a sheet of copper and I'm debating bolting some sinking made of that to the top sides of the MOSFETs. Last night I learned that the power supply works a ... | |
| DIY Pass Labs First Watt F5 amp impressions I got my boards, transistors, and case through the diyaudiostore too. Real good stuff. I'm definitely getting excited to hear it. I think my next project is going to be a B1 buffer pre-amp. Need to dig into that world a bit and learn more though. ... | |
| DIY Pass Labs First Watt F5 amp impressions I'm currently a matter of hours away from finishing a 50wpc version of the F5 using the standard F5 topology, not the F5 Turbo. (32V rails.) I'm getting very excited to hear what it's like. It's the first amp I've ever built so I'm not rushing to ... | |
| Schiit Vidar.... Anyone heard one yet? They were showing one last year and were claiming to have it out by now. Weren't they saying November of last year? There's only two possible reasons it's not out. Either they're having issues producing it, or they're having issues finishing devel... |
