If you don't want to spend much money, buy the least expensive one.

How about none of the above. Chinese parts quality is highly suspect. Printed circuit boards don't lend themselves to modification. Neither schematics nor links to them have been provided.

Remember, a true bargain is very rarely low priced.

I like the last one in aluminum enclosure. Acrylic is ugly and with open one you have toake some "boxing".

I have few amps from China and I changed components with genuine transistors, tubes, audio caps etc. I did it for my relax 🙂

My overal experience is positive, when I can resolder boards...

Most likely, you're paying the same amount for internet access as all three of these cheap preamps would cost. Plus, with the cost of electricity, don't think electrons are cheap.

Cheap stuff like this, I probably spill more than the cost of these preamps per month. But I have a lot of fun.

Only the second item is a preamplifier. The first is impedance matching ,high to low , the third is to adapt magnetic pick up turntable . I like the second one . Probably you will pay more for only a pair of tubes shipment included from USA .

Although it can still be fun trying new things; trying the cheapest version of something is generally not a good way to get a feel for how it is. I think tubes often get a bad reputation as having a mushy and highly distorted sound based off of people getting badly designed or worn out tube amps.
