Dali MegaLine overviews from owners ?
Kurt_tank, Albert certainly has a lot of power but even he will tell you that he doesn't use it. We suspect that his amps rarely make it out of class A. On the 750s that's not a lot of power.As to 'thunderous bass' I am quoting one of my customers... 
Is my amp "High Current"?
Nsgarch, you could have used a better example than an ESL. How about a B&W? ESLs are neither looking for current or voltage- they are expecting constant Power. That is why tube amps generally sound better on them too, so long as they are able ... 
MC TRANSFORMERS VS TUBE PRE PRE
I have yet to hear a transformer that can do what a proper tube phono stage that is capable of MC operation can do on its own. The transformers rob detail, bandwidth and are less interesting to listen to. 
The passing of Marianne Barber of Joule Electra
Jud and Marianne always treated me like- well, I felt like a family? that I never had, even though we have only met a few times. My condolences as well. 
Tube amps and speaker ohms
Hi Pauly, here's what's up with four ohms: Yes, you can use the 4 ohm tap, but at a price. On most output transformers that have a 4 ohm tap, measuring the response of the amplifier on that tap as opposed to the other taps will reveal slightly low... 
Reference level playback
Acoustat6, Having made a few recordings, I respectfully disagree. Usually an LP, and CDs as well, are recorded to take advantage of their dynamic range, resolution and noise characteristics. It turns out that in both cases it is advantageous to re... 
What Makes a Good RIAA or Line Stage?
It is really helpful to work with live recording sessions and master tapes, especially if they find their way to LP! I've done a lot of recording and after a while you get used to the way your mics 'hear' and place them where they will get the eff...

Albert likes his speakers a lot. We have a customer running a set also; what we have found is that the speaker is very easy to drive and does not need a lot of power for thunderous bass- 100 watts top and bottom is plenty. 
amplifier DB meters
Nice! I think my SF2 is the only twin on the road in the Twin Cities. Seven SFCs together at the same time.... 
Tube Pre-Amp Question
I would also try floating the AC ground on your power amps. You might be experiencing a ground loop if the power amps are grounded through the AC cords. 
Tube amps and speaker ohms
Anytime you are investing in tube amplifier technology, that investment will be best served by a speaker that is at least 8 ohms or more. Tube amps, with rare exception, have reduced performance into four ohms. Given that you have satisfied that p... 
What Makes a Good RIAA or Line Stage?
Two of the main points I can't get around are:(1) Whether or not a cartridge is a balanced or a floating single ended device. Floating single ended makes more sense to me.and(2) Since everyone more or less agrees that there isn't a 6dB noise advan... 
tube amps/low capacitance cables?
Whatever the deal is causing the lack of bass with that cable, its not capacitance. Length, cross sectional area and the characteristic impedance are more likely variables. By decreasing the 'damping factor' the bass would actually increase, altho... 
What Makes a Good RIAA or Line Stage?
Hi Thom, what is it about my explanation that you do not understand? 
Older PURE CLASS-A Amplifiers
There are a lot of Class A tube amps too- any reason they are not on this thread?
