Will an Amp change improve my system ?

Amp that will match your speakers will definitely a game changer. For 15 yrs my eggleston Andra were not maximize if I will get powerful amp I get good sound but no musicality I like. Until I found the Tsakadiris apollon monoblock using KT 120 tungsol powerful enough to drive my Andra to give liveness and musicality.it was a perfect match.

Bryston 14b3 or Bryston 4b3 amp.  Use a great tube preamp with the Bryston and you would be surprised at how good it will sound. The crucial choice is the preamp because the Bryson's are pure, neutral power...solid and dependable. In other words, the preamp you chose will determine the quality of your audio output while the Bryston simply delivers it to your speaker choice.

Put the best power cord you can afford on your main source, then everything else before doing your interconnects. Check out Shunyata Power Cables. You might also want to upgrade your wall sockets and power strips to something higher quality like an Isoclean. Or get the new Shunyata Power Distributors

@carl292 I have been looking at the Schitt Wotan mentioned above and have been discussing the amp with owners over at Head-if. They are a lot of Schitt fans there, so I take that bias into consideration. From what was said I am going to order the Wotan amp and compare it with the CODA #16 I have. If the 2 amps are in the same sonic ballpark, I am going to sell the #16 to get a headphone and keep the Wotan.

The Wotan uses fans but that is not a concern for me these days after my good experience with the KRELL DUO 175XD which also used fans. Though I do not know it ever turned on.

@yyzsantabarbara I'm also interested in the Wotan and the mono Tyrs which are on sale last call.
