Need replacement for garden hose Audio Advisor
Gumbydammit, you were amazingly accurate at guessing my age/ears. Only off by 1 year! I'm 46. Although I can still hear highs ok. I did some mods to my Fostex drivers impedance characteristics to extend the high and low ends. Worked out well. I ag... 
Which SPEAKER for the 21ST century?
How about this for a 21st century speaker. A full range plasma point source driver! 
Rolling your own
Yes, I've made a lot. My advice is to start simple. You need to get on the learning curve. If you build a complex design and it doesn't sound right, you have no idea what to do to fix it. The usual starting point is a 2-way monitor. This will get ... 
Okay, the gloves are off. Let the fur fly
Greg, the phase problem you mention is only one of the many phase related problems. Phase induced distortion/coloration is another. Sure, there are methods of addressing these problems. My contention is that the cure is generally worse than the or... 
How Can I tell if the tubes I bought are vintage?
There are several websites that address this subject, just search for NOS TUBES. The tube vendors usually have a section that talks about that. I got my tubes from Kevin Deal at Upscale audio, who is a member. Very good results. 
35Hz - 25kHz -- A Partial 'Purist'?
Wonder of wonders! I would actually consider an active crossover and sub, with dedicated amp if, and this is a VERY big "if", I could seamlessly integrate it low enough to keep it out of the lower mids. I know that this departs from my normal phil...

Paul, glad to help. 
What is the future of amp technolgy?
Thanks, Ghostrider45. At least that gives me some basics to work with. Much appreciated. 
looking on preamp to match otl amp.
If phono is all you do, then you might try just a phono stage with a volume control, as a minimalist approach. If you want a full preamp, you might try the Supratek, from Australia, that is being heavily recommended on the "preamp deal of the cent... 
Why no threads on OTL amps?
I like all OTL's and many other amps as well. It just seems to me that as soon as something was said about Berning vs. other OTL's, the fur really flew. Very interesting. Seems to be a very sensitive issue. I hope everyone is enjoying their amps, ... 
What is the future of amp technolgy?
Viggen, that brings up a good question. What is this digital amp technology? I confess that I know next to nothing about it. Maybe someone can enlighten us. 
Okay, the gloves are off. Let the fur fly
Paul, you are correct on both accounts. A speaker down 40 db at 25Hz or any thing like that could not be considered accurate at that frequency. The question is what do you do about it? This has been the discussion above. Read some more above posts... 
Okay, the gloves are off. Let the fur fly
Zaikesman, I currently use a Fostex FE103 based single driver system in a tubular transmission line configuration, tuned to 41.7Hz. Since the FE103's are only 4" drivers, they will not be everyone's cup of tea. But they are common in high end syst... 
Why no threads on OTL amps?
Without trying to be argumentative, I agree that if one wants to call the amp non-OTL because of the "coupling transformer", this gives one an ostensibly good reason. On the other hand if one wants to call it an OTL, one can use my reasoning in th... 
Okay, the gloves are off. Let the fur fly
Zaikesman, I completely agree with your insightful observation on the box speaker evolution/development. I hope that in coming days, you could change your view of me from "agent provocateur" to "interested participant with a unusual point of view"...
