Tube and SS pairs


I was wondering what are the advantages/ disadvantages of tube preamp with SS amp versus SS preamp with tube amp combinations.

I can see the cost advantage of wanting to add more of a tube sound to an existing SS amp. But I was primarily curious about the different sound characteristics of each set up, theoretical and hopefully from your experience.

Thanks in advance

What I learned is that there wasn't an ideal choice; there is an  overabundance of terrific gear; the options and pairings really are endless; and final choices (imperfect though they are) have to be made.

Yep, unfortunately nothing, absolutely nothing, replaces auditioning; especially auditioning a component in our rigs. As much as we would like, because it’s easy and involves little effort, we can only believe little if anything, we read. What we can do, is add what we read to our knowledge base and continue building that, until a personal experience proves our tentative conclusions. But until we find someone with our exact same system and we know that our audio priorities are similar to theirs, making conclusions, especially buying ones, isn’t recommended. But unfortunately because of logistics, it’s understood that buying unheard, can't be prevented.  

If an audio store isn't nearby, attending an audio show (albeit not great conditions, nor easy to judge what a specific component is doing in the chain), provides a highly recommended learning experience.  

As a long-term (read old) audiophile, I can't tell you how many times my preconceived ideas about brands, component types (ss, vs tubes, analogue vs digital, digital direct to amp vs pre-amp to amp, cones & domes vs panels vs horns vs open baffles etc.) have been modified, crushed etc.... Thus, with all things audio (and life in general) one should always try to maintain an open mind. If that is done, surprises and forehead slaps abound and great finds and experiences will be the result; these will be in place until another surprise avails itself and we again learn and decide to move on…and so it goes.


I'll limit my answers to the question at hand.*

Typically ss pres to tube amps will better match sensitivities.

Typically ss pres to tube amps will better match impedances.

YMMV!!!

*The matching of ss or tube amplification to speakers is typically more important!

IMO with a hybrid system you still miss a certain organic sound that only all tube systems provide..Todays tube amps use the best power transformers available and can control properly chosen speakers with just as much authority as SS.Gross miss matches aside the best systems will always be:
All tube...
Hybrid (Tube Pre/SS amp)...
By accident, I placed a "ifi Microitube 2 preamp" as a *buffer*, between the oppo 205 and my old SS class AB amp and was floored by the improvement. Been enjoying this set up for months without fatigue.

The ss preamp that was designed for the amp will now collect  dust.

I have also gone back to listening to my bipolar speakers which seem to break up the limitations  from the small room I am in. 

I would highly recommend this small addition to anyone who feels their SS amp is too harsh or clinical sounding.

Clearly, contrary to my flawed logic, tube preamp and ss amp versus ss preamp and tube amp is the right a d cheaper way to go.

Thanks for everyone's input
