Total BS look at the Qualiton A50i. Also, Toroidal transformer and is fantastic sounding piece of kit. BTW most of the components are built in house. @audioman58 read up a little.
A pure class A tube amp would be under 20 watts in a Tube amp ,
50 watts pentode or ultralinear , and$2k is just a starting point fora tube amplifiers
One ofthe key elements is the transformers ,and chokes ,brand name like Lundahl
that Ayon uses excellent C core type for example is far better then , any Chinese amp like primaluna , they use torroid type which no Highend company uses.
and inside the resistors,capacitors everything counts , I have had several Ayon models theirSpirit 5 is ideal triode,or pentode ,even the tube sockets solid copper
not cheap $3 brass type far better conductivity ,and machined aluminum cases, night and day better, less vibration than sheet metal, ad microprocessor controlled per tube bias, not All power tubes averaged out like most. Tubes wear better and optimum bias, better sound and they are using the very good kt150tubes.
when a tube goes bad it does not blow a transformer it goes into standby ,shows you the tube , just replace the tube ,hit there bias button and up and running .
yes abit more monies but very high quality from Austria.
