Very rare to have a good sounding cheap amp.
Call me i will give to you a list of cheap very good amplifiers....my sansui AU 7700 is unbeattable for the price: 100 bucks and 6th year of working in my room 12 hours each day....
Try to look for a very good and low cost dac? This is HARD, good luck..... 😁
I bought a NOS french dac which use only one old chip TDA 1543 in a minimalistic design... Sold on EBAY by Starting point systems...Christophe Mariac designer...
He is so good i want to buy another one used in case...If someone want to sell one call me.... 😊😁😁😁😁😊
I will bother no much ever for a dac, because in my actual acoustical settings i sense NO limitation at all coming fromt it...
And my audio system for his price is so well embedded that i dont listen to my 7 headphones anymore, i dont like NO other system i listen to more andi dont to want to upgrade or buy another one....
It is not the best system there is at all, but when all music is there filling the room without heavy limitations, we listen music without thinking about a new component....
Then my greatest purchase luck what the luck to buy one of this dac....
A good dac at LOW price is perhaps the harder piece of gear to discover and bought....harder than even buying low price good speakers....
I am born under a good star.....
Then yes, old designed cheap could be more good or than dreamed of because most people has never listened to their own system at his peak working potential at all anyway.... Often the real causes of theor unsatifactions unbeknownst to them, comes from the bad embeddings controls and less than from the gear they already own.... Then instead of adressing the more complicated questions like vibrations controls, electrical noise floor controls or more importantly acoustical controls, they search for an easy solution: an upgrade....And the more evident one : a costly DAC....
I think it is not the vintage chip TDA 1543 which only explain the result i listen to but more the MINIMALISTIC way and the low noise which is associated also with the internal battery....I connect it to a good power supply also: IPOWER ...
