Emmeline XP-7 performance value - by the numbers
The performance of this amplifier has been most compared to the DIY PPA. The PPA can be purchased starting at $350 with no power supply. The Emmeline XP-7 can be purchased for $500 with no power supply. Under the premise that both amps perform at the same level and are of the same build quality, it is logical to conclude that the PPA is $150 of better value.
Real life considerations
Why do people then purchase the Emmeline XP-7 over the PPA? Because they feel spending more money is justified by what they may get with the Emmeline XP-7. Let us discuss some of these details.
The Emmeline XP-7 is a small portable design. A PPA could also be constructed almost as tiny as the Emmeline XP-7 by squeezing the same Bulgin 2x9v battery case with a PPA board into a small enclosure. Mind you, it would take some doing to make it fit. The end result would most likely give you only a fraction of the battery life that the Emmeline XP-7 has.
I think that my Emmeline XP-7 could take my full weight if I were to stand on it. The build quality of the Emmeline XP-7 is backed by Ray Samuels. Much of the cost of any headphone amplifier is also based on the reliability of the unit and reputation of the builder. I am certain that you could have a very fine portable PPA built by one of the reputable PPA DIYFSE builders easily for $500. I almost went this route when I purchased the Emmeline XP-7. However the builder canceled my PPA order and I was soon tempted to own a Ray Samuels Audio product. I wanted the Ray Samuels brand kind of like women want a name brand purse.
Design value
This argument has been brought up quiet a bit with other amplifiers. Often this argument comes down to “Does it really matter what is inside if it performs well?” If you can find a reputable builder that can build you an Emmeline XP-7 as well as one built by Ray Samuels go for it.
Honest candid opinion on Emmeline XP-7 value vs PPA value
The most attractive value feature of the PPA that still attracts me, is the numerous options for power supplies. You can use a $30 Elpac, or $100 STEPS, or even better if you so desire. The PPA is a much better value for home use. For $380 you can purchase a PPA including an Elpac power supply. The cheapest Emmeline XP-7 with power supply is $700.
Conclusion
Having owned the Emmeline XP-7 for over three months, I can say that I do not yet regret my purchase. Had the commissioned PPA builder not canceled my DIY PPA order, I would not have given the Emmeline XP-7 a chance.
The Head-fi DIY community is flourishing. They provide opportunities for our members to attain headphone sound that some could typically not afford. Opportunities have been raised higher yet again with team PPA’s successful design. For value the PPA appears that it simply cannot be beaten.
However for portable use are there many headphone amplifiers that can beat the Emmeline XP-7?
