A critical review of MHZS Tube CD Players
Nevermind the sound, the build quality and soldering is disgustingly shoddy. There are more bad solder joints than I care to count with blobs of solder all over the place, cold solder joints, and joints without enough solder. $50 DVD players have better solder joint quality than this piece of...- Roam

Woo Audio 4 or Single Power Extreme for K701
SinglePower Extreme, on the basis that the Woo 4 uses 12AU7 input tubes. 12AU7s were never designed for linearity and they can't be made to run linearly, they belong in guitar amps and have no place in hi-fi. Even a run of the mill 6SN7 such as the GE 6SN7GTA/B will handily outperform the best...- Roam

Have You Tried - Valab Sound Enhancer Input Transformer?
A transformer will break ground loops which reduces or eliminates hum & noise. Assuming the transformer is of decent quality, this will improve the sound.- Roam

How do you identify unmarked tubes?
Some tubes you can probably identify by their structure, a tube with "mouse ears" is almost certainly a Tung-Sol 6SN7. If you're lucky you should be able to recognize a few tubes this way. With VR tubes it should be pretty straightforward, put together a simple PSU and use an inline resistor...- Roam

No-Sound Cable Break-in? Possible?
Find a 60W lightbulb and the socket to go with it, they're readily available at any hardware store. Wire the speaker cables to the socket and adjust the volume until the lightbulb glows nicely. With the right music, you can even watch the bulbs flash in synch with the beat.
