Where do the tubes go?


I have so far been a solid state guy, but I am looking into another system, and I would like to give tubes a try.

1. Would most people recommend an all tube system, or do you recommend starting with only a tube component or two.

2. What are the relative merits and disadvantages of placing tubes at various stations in a system CD-->pre amp --> amp ?

For instance, I have read that some people feel that that the micro-distortion (pleasing though it may be) is excessively magnified if started at a source component then magnified through a bunch of high power solid state electronics. Others have advocated that having tubes early in your system gives the tube sound quality and allows for higher power, lower maintenance/heat solid state amplifiers.

For the tube experienced, how where should I start integrating tubes? (starting a new system so disregard concerns of mating to existing equipment).

No stereo component functions alone, or at its best with just any others, so always best to consider the key component inter dependencies, especially when dealing with SS versus tube based gear.

Assuming you have a good system already, and are looking to add another built around tubes, I would set a budget for the new system that is built around tube amplification of some sort and go from there.

How that might best play out would then be determined by what your goals are for the system sound wise. Room size, types of music listened to, volume to be listened at, all the usual factors should be considered up front.

If you are just looking to add some tubes into an existing system, a tube source like tube DAC is the most practical place to start. Tube rolling in a tube DAC will provide opportunity to experiment easily with different tubes to tweak the sound and learn initially.

What speakers do you have currently? That would be a big factor in determining whether a change to a tube amp or integrated is a good investment alone.

A tube pre-amp is another option, but I would consider input impedance specs of whatever power amp was to be used with it first before doing that, and only if a analog pre-amp is needed, ie in case of both digital and analog (like phono) inputs. 30Kohm power amp input impedance or higher is probably a safe bet for good performance with most tube pre-amps.

No right or wrong way to start. Just some more likely to work out better sooner rather than later if you always consider the big picture before making a move.
