Tube Monoblock location? - Rack or near speakers?

Hifitime, if you think about it, a tube amp sitting beside a speaker is not going to get any more vibration than one far away. But really, if you try the difference between long speaker cables and short interconnects as opposed to short speaker cables with the amps near the speakers and long interconnects, the across-the-band improvement is instantly audible. IOW, apparently the vibration issue does not seem to play a role.

Ralph I always wanted to ask you if you are a fan of tube dampers for pre and power amps?

Atmasphere,I would never want 35'long interconnects in my home like you have.I have tried numerous combination's with interconnects and speaker cables.My friends and myself all agree and all have longer speaker cables instead.Lower level signals pose more of a problem with longer cables.In theory balanced cables may work,but they are even more prone to RF noise than speaker output levels,and this isn't news to you.All brands.The vibrations from the speakers causing abnormal microphonic music is a nightmare.I can't imagine anyone liking this effect.Microphonics have been a known and proven problem with tubes,and even capacitors too.Wilson Audio and other high end speaker builders even use vibration isolated crossovers to help keep vibration noises from affecting the sound.Tubes and speaker vibrations have never got along,and I've never seen any other solution to the problem other than locating them in the least vibration prone areas of the room.Every room in my home has different areas that work best for keeping tube and vinyl feedback down.Distance itself works good for starters.

this may have been addressed earlier but here goes. It comes down to real and reactive power and IxIxR (I squared R, or power) losses on the cables. The current running on speaker cables is higher than on interconnect cables. Consequently the power losses on the speaker cables by using the equation above can make a drastic difference. It is typically better to have short interconnect and short speaker cables, but if you can't have it your way, then short speaker cables and long interconnect cables. This is simple electical engineering. There are less power losses on the long interconnect cables than there will be on long speaker cables. Also, there are reactive losses that increase/decrease the reactive impedance of the cables depending on the frequency of the signal. So, the general rule. Use cables as short as possible. But, if you can't then short speaker cables and longer interconnect cables. But, that means that the interconnect cables must be really good, properly shielded, etc. No matter what people say, it comes down to the ampacity of the cables and the impedance of the cables. That is why changing cables makes sometimes such a huge difference in sound. The manufacturer is playing with the impedance characteristics of the cables to alter the music signal and hence the interaction with your equipment and ultimately, the sound. This is not rocket science, but it is science.

Minorl, what would you consider as an acceptable run of speaker cable (length?) thanks
