Problems with my Berning ZH270

<
Hi and thanks. I am comparing with my old Gryphon Callisto integrated amplifier. It sounded softer but, incredebly, the ZH270 has better low control.

Hi Tubegroover. My room is 5 meters long, 4mt wide and 3mt high. I didn´t has problems with my older systems. A friend of mine is going to bring home his ZH270 to compare to mine, so I will no if there is anything wrong with mine. If I can´t resolve this problem I would go back to solid state, keeping the Joule as pre. After trying for so long is sad, I really hope my ZH270 can go well. My speakers are placed more than 1mt away from the back and side walls. I have a big carpet and I have used the alignement tool provided by Merlin. Thank you very much.

Hi. I don´t live in USA, but I bought my Berning from Allan, brand new. Yesterday I change my NOS Telefunken and it seems that the sound go better. I change the tubes inmediately after receiving the amp, I have not listen to music more than few hour with the original tubes. My fault.
Thank you very much for the help I have received from everyone.

I have a Lovan Classic rack "upgraded" with a silestone shelf.

Thank you. Have you tried the 12AT7 Brimar black plates or the 12AT7/CV4024 Mullard CRYO ??. Would I have a warmer sound from them?. This is my first tube amp and I just learning. Thanks again.

Hi Allan. How can I contact Andy?. Thank you.
