Preamp... Solid State or Tube

It comes to what do you have for a amplifier and how detailed it is 
I have been doing this for 40 years and In my opinion a great vacuum tube pre amp complements the Solid state you get better image depth and more dimensional  with Vacuum tubes.
Leading edge detail will be more defined with solid state preamp.
Also type of tubes makes a huge difference also
Budget has the biggest factor Coincidence has a great preamp 
For under $6k these tubes  were designed by Western Electric 
And refused to license to Anyone the A 21 tubes I believe that is the number are very natural. This is just my opinion and a solid example.pass labs makes a nice one Reno aufio sells used that are excellent.

@lancelock,  the ZTPRE definitely peaked my interest.  Loved the high rev video :-)

What is the retail? However I feel, three inputs leaves very little room for any future expansion with one input occupied as HT bypass. 

@bpoletti, good recommendation. But I am not considering any single ended preamp. 

Agree, but who said one is better than the other? Isn't everyone just stating what they have or have experience with? No doubt when you start spending this kind of money there are many great SS preamps. I came real close to buying a Pass XP10 which is a fine piece. For 10K I'm sure the XP20 and other SS preamps in that range are to die for. Funny how everyone describes these great SS preamps,  they often refer to how close it sounds like tubes... same with amps. Best bet is listen before you buy, and if that's not an option talk with the designer and chances are they will sale to you direct and refund you if you don't like their product. 

There's both great tube and SS amps as well, but for my money and taste I prefer SS. I enjoy tube amps a lot and have heard a ton and have owned them as well. I personally don't want to mess with the cost and maintenance of retubing an amp. For the most part; retubing a preamp isn't too costly and tube life is far greater.

Everything listed on this post have been great options and I bet most of these companies, when you call the owner is probably the one answering the phone. You'll have to eat some shipping cost but I'd call them and demo the ones that interest you and see what happens from there. 

Good luck
