Is this an excellent value?

I happened to come across this listing by chance!

This appears to be an excellent value.

Two mono SET 845 25W amplifiers and Pre amplifier at 2551$.

It also can be wired for 120V power.


But I had never heard of company called "Yaqin "before.

What is your opinion on this combo?


The specs are as follows.

Output Power: 25W + 25W (8Ω)
Distortion: ≤ 2.5% (1kHz)
Frequency response: 10Hz - 40kHz (-2dB)
SNR: ≥ 86dB (A)
Input Sensitivity: ≤ 0.2V
Load Impedance: 4Ω - 8Ω
Tubes: preamp: 12AX7 × 2 12AU7 × 1
power amp : 12AU7 × 2 845 × 1
Power Voltage: AC110V/220V 60Hz/50Hz
Volume: preamp: 275mm x 195mm x 390mm (D x W x H)
power amp: 315mm x 395mm x 435mm (D x W x H)
Gross weight: preamp: 12kg
Powe amp: 28kg x2 (a pair) = 56 kg

That is too bad!

It looks so beautiful but with sad history long time ago.

Thanks a lot Stereo5 for your comment
If you want to get into a higher-power triode SET amp, it's hard to fault Yaqin or Valve Angel on a bang-for-buck basis, You might want to look at Bottlehead or Decware, too, And as roberjerman said above, speaker efficiency is key.  Get a set on the 90s, they're available now, and some are really affordable.

My speakers are supposed to have efficiency of  99db/W but I believe it to be around 92 still not bad.

But my listening space is pretty big so I need at least 40 Watts of Power.

Thus I am more inclined to Line Magnetic 508.


"Get a pair of Heresy's. Efficiency 99db at 1 watt!" 

They are rated at 96db 1 watt/4 feet, and Klipsch is well known for their rating's being rather uhh, well, optimistic we'll say. 

But they are very efficient. None the less. I like my Klipsch speakers. I have at least a couple in my pile, but I take their frequency response (at both ends), and sensitivity specs with a grain of salt. 
I'll probably get ripped for saying this, but what the hey.  Why would any one want to buy an upstart Chinese amp/preamp from someone who wants to get rid of it when you have so many safer choices of quality equipment in the same price range???
