going from tube preamp to solid state

@innersound300 imo, listen to @aricaudio who knows your preamp design.

I was about to suggest the same as Aric. I’m currently using a 6SN7 preamp with various tubes in the stable. Every single/different tube I've tried (NOS vintage or new) offers a different sound, presentation, level of detail and stage/focus can change. More info about your existing tubes in that preamp may help too. 

i.e. my NOS Sylvania 6SN7 long black plates are uber detailed and almost too forward and open compared to my other/smoother softer PSVane or TJ Full Music ’SN7 tubes, or new reissue Tung Sol 6SN7s a bit more rolled off. However, with your speakers and tweeters, might be a match for you. It’s a balancing act.

Have you already tried a few other 6SN7 or 6SL7 tubes in your preamp, as Aric is kindly suggesting? This is a start and common to try among members here. He mentioned caps too, yep, these can be changed too, ask Aric more imo. 

Amp/Cables/Speakers:

Reviewing your Innersound 300 amp, (i.e. similar to Coda 3.3 Stage), right?, I don’t think your amp is a culprit as much as it might be fining a combination of the 1) correct ’SN7 tube in your preamp 2) if you’ve not already tried possibly more transparent interconnects (yes it can help) to try on loan, between your sure and preamp, and preamp to amp 3) then if still not resolved, ask your PBN speaker manufacturer if there is a more open crossover capacitor or slight crossover/x-over change to open up that tweeter a bit more, is it rolled off some? Maybe so, worth asking them. Some small changes might go along way here first.

imo, several things to try long before jumping off the cliff to another preamp.

Here's one you might be interested in (Google the model # to find the US/Canadian vendor).

I'm not a 6sn7 fan either (preamp gain and as driver tubes).

audiogon suspended my account so had to create a new one

i have tried other 6sn7 tubes and some like you say were to bright sounding, so didnt care for those.....i think those were the rca's ( could be wrong ).   i have tried the sylvanias also and like those as they are a bit more laid back.    

 if you’ve not already tried possibly more transparent interconnects (yes it can help) to try on loan, between your sure and preamp, and preamp to amp 3) then if still not resolved, ask your PBN speaker manufacturer if there is a more open crossover capacitor or slight crossover/x-over change to open up that tweeter a bit more, is it rolled off some?

i have tried other IC's and it changed things, but not enough.

there is nothing wrong with the speaker, i dont need to have the tweeter opened up more, there is plenty of detail.      

@youwin I received your Audiogon message and they will not let me reply to it with any personal info. If you could, please send me a message through my website, let me know your name and when you purchased the preamp (so I can reference it), then I should be able to help. Best regards, Aric

@youwin good to know, and hopefully working with Aric a bit more to explore more can help. For some reason you decide to swap out your current preamp for something else permanently, I’m betting you won’t have a hard time finding a new owner if you decide to put it up for sale. Best of Luck on troubleshooting the next steps. I for one am a huge fan of well designed 6SN7 preamp / line stage units.
