Tube amp for Dynaudio Contour 2.8 speakers
I think first you need to find if the soft bass is from the speakers or the amp. You could try to borrow or home-demo a high-power (wattage) solid state amp with your speakers to see if that improves the bass. If it does then a new amp would help.... 
Hearing affecting soundstage
The problem I have is not that the soundstage shifted one way or another. The center mix is still there. Vocal is still right at the center.But with recordings that have a diffused background sound or a background orchestra, the back soundstage is... 
Vocal Jazz recording with wide and deep sound stag
I meant CD. Thank you. 
Arcam CD-33T FMJ vs Rega Jupiter 2000
I think it's a matter of taste. Jupiter is more musical while the CD33 more exact and precise. 
Isolation Platform - to be or not to be for CDP?
Mine's are four rolled up socks from Costco, honestly and it works just fine. 
Are new tubes supposed to do this?
I think it was a bad tube I put in. After putting back the tubes that known to be good, everything was fine.Thanks for all input. 
Are new tubes supposed to do this?
My other tube that was good now went up in flame too. Somehow the bad tube is now affecting others ... like a virus. 
Are new tubes supposed to do this?
John: I am not sure if the amp delays the B+ at turn on.On thing I forgot to mention is that I replace the tube when the amp is slightly warm. Maybe there was a mismatch in temprature between the tube at turn on but I am not sure.On thing I notice... 
Switching polarity of tweeter in two-way design
As for tilting the baffle to align time and phase of the tweeter to the woofer, does the degree of tilting depends on the x-over only or only on the acoustic characteristic of tweeter itself? 
Gallo Acoustics Reference III vs. Hyperion HPS-938
Gaudio_eek: That is a only preview. The reviewer did not make any atempt to compare the two speakers. 
Weather-induced amp performance variation
Eldarthford: I guess age of the listener has much too do as age of equipment :-) 
Driver efficiency vs. overall speaker efficiency
Sorry , I meant 87.5db. It was a typo. I was looking at various Vifa and Scan Speak mid-range drivers and almost all of them has an efficiency rating of 87db or less. So I was wondering how one can build a speaker using those driver but can achiev... 
Spendor S5e vs. S6e?
What HiFi actually prefered the S5e over the S6e by a wide margin and the S5e has received nothing but high praise from pretty much every hifi publications out there, while a couple of reviews from What HiFI and HiFi Choise on the S6e have been in... 
Spendor Audio vs. B&W Nautilus Speakers
I think you have to be careful about system matching. If you have quality amp then I would recommend B&W. But since you mention you'll be using Rotel which is a rather bright amp, I would not recommend B&W since B&W are very revealing.... 
Capacitor-less amps
I think what he meant is that no caps in the signal path. I think Arcam Diva series do not have caps in the signal path either. They use some kind of servo circuits on the output to remove any DC residual.But for the power section of the amp, ther...
