Can someone guide me as to what Single driver ??
Hi Sean,Glad to hear you put these great Emminence drivers to good use. They are a true miracle value when properly used. I should point out that there are some significant construction differences between the commercially available 12LTx driver a... 
Can someone guide me as to what Single driver ??
Hammer Dynamics Super-12 kit ($650, 97dB/8ohm)It uses a 12" fullrange single-driver for 40Hz-10k+Hz, then a coaxially mounted supertweeter is used for 10k+Hz and above. 1st order crossover to minimize phase shift and distortion. It is is mounted i... 
Passive Pre - No Regrets?
Pubul57,Wait until you get 100 hours or so on the Placette, bet things just get better and better. Take your pick as to whether passives actually "burn in" or it takes a little time to notice all the extra fine, subtle, details that get through. B...

Herman wrote:"I don't see this as a drawback as the issue with DC is no different if you use a resitive voltage divider of some sort."But, both Autoformers and resistive pres are significantly different than a TVC in that regard. Galvanic isolatio...

Can't get any better match between source nd amps than that, Jsadurni. "If it ain't workin' for ya, it ain't workin!"The only other question is what type of interconnects are you using and how long are they? I've heard that capactance and inductan...

Jsadurni,1. What is the output voltage and impedence of your sources? 2. What is the input sensitivity and impedence of your amps?3. What type of interconnects are you using?

Gotta admit, that used Atma MP-3 preamp that was for sale here at $2k had my bank account shaking, badly. 
DIY do it yourself tube amp kit
Are OTL's good with low impedence electrostats? At the crossover region of 125Hz, I think those speakers were known to drop down into the 2-3 ohm range. Not an easy load, at all.

Remember that those interested in autoformers have to be sure that there is absolutely no DC on the output of their sources. Any DC getting through can be bad for amps.By contrast, one of the primary benefits of transformers is galvanic isolation,...

Good point about phono preamps, Electoid. My solid state Gram Slee Era Gold mkV phono preamp(+ELP "transformerless" stepup) has an output of 240mV - 1.08V max. That's works for my Art Audio PX-25's 0.7V input, but not really enough for my Welborne...

"Great story Moebis!! He's still just as stubborn about tube amplifiers being the only amplifiers to use!LOL"You mean, it's not true? Actually, I'm a low-power SET guy, but not so much so that I don't appreciate other approaches. "I had to laugh a...

A funny story for Atmasphere(and others),4-5(maybe 3-4) years ago I called Jack Elliano of Electra-Print (of transformers and DRD/Ultrapath amps fame) about winding a transformer volume control for me. At the time, S&B TVC's seemed excessively...

"There is a good and simple reason there are so many comments on this thread favoring active line stages: the issue is real."There are even more favoring passives. Not that either proves anything."But any line section that has a low enough output ... 
Graham Slee GSP Era Gold Mk. V - anyone have it???
Good point on the price comparison between the upgraded EAR 834P and the GSP. A more fair shootout would be the new GSP Reflex and modded 834P, although the GSP is still significantly cheaper, I think.I preferred the GSP over the Rogue Stealth and...

"I will try the oop blanket (1000 + hours ?)."Eeeks! That's 41.5 days of non-stop playing.Be careful about how long and how loud your run any speaker's driver non-stop early on. Speakers are electro-mechanical devices and heat does builds up in vo...
