Tubes don’t make it better ,you need to spend $3k used and up
for say a 25wpc class A pass Labs which is more power then it sounds .
it here is No good tube amps at $3k . Quality tube amps cost $$. No getting around it . Any quality tube amp has good transformers and chokes like Lundahl, Hashimoto,Tango for example. are C core transformers ,look at all Quality amplifiers , you will not find any Torroidal transformers in a high quality tube amp , Ayon, VAC , CJ, AR ,Luxman, Audio Valve,Jadis and many more look at custom tube builders Like Radu Tarta, or Thomas Meyer, my point is Audiophile quality products cost $$.
