Anyone know these decks ? What are its specs ? how good are they compared to Alpine 7909's ?
It claims 20 bit DAC ?
Is it a 4v ?

Those decks are 18 years old. The CD mechanism and the laser pickups are both discontinued. If the deck were to quit working, getting the parts to repair it will not be easy.
7914/7915 were 500mV units, as were the original 7909's.
7914/7915 were the first Alpine CD's to depart from analog preamp functions, and as such aren't as desirable as the 7903/7904 IMO. They used one rotary encoder for volume, bass/treble, balance and fader. They were 20-bit hybrid "Interpolative DAC", which was some combination of 1-bit and multi-bit.
Nothing else Alpine made from that time period was comparable to the 7909. It employed a 30V bipolar power supply to achieve superior preamp performance in terms of THD, dynamic range, channel separation, S/N ratio. Legend was they used better DAC's than the rest of the line as well, but I'm not sure about that.
Parts are hard to come by, but my 7904 (1990 or so) is the model before the 7914 and still works like a charm in my daily driver.
Buy one if you want it, just don't invest much into it.
