2. amps-preamps

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

I had a Yaqin hybrid integrated.  After the first week, it caught fire and almost burned my house down (NOT kidding).  Thank God I was in the room at the time and I was able to run to the kitchen and grab the fire extinguisher.  My upstairs room smelled for a long time after.  At the time I bought it, it was only being offered on ebay.  I got my money back through PayPal, but never again would I buy cheap Chinese junk.  The amp was so cheaply made.  Under the polished transformer covers was a transformer that you would use in a transistor radio, they were that small.

Like we used to say about certain cars, all show and no go.

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.
