Has anyone modified the Emotiva XPA-5 or know of anyone who has? I'm intrigued the whole modding trend.
The mods I have in mind are the following: a pair of Bybee quantum purifiers, replace the secondary capacitors with either jensen, nichicon, or mundorf capacitors, a custom diode bridge from reference audio mods, and replace all the wiring inside with pure copper wires. Perhaps even replace the toroidal transformer with one from sonic frontiers (not sure if compatible or not) or another compatible brand.
If anyone has modified any of the other emotiva amps in the lineup then please let me know.

First of all, those so called bybee quantum purifiers are nothing but pure BS, they dont and cannot do anything what so ever, a passive inline component cannot purify a signal/mains voltage by removing noise and such. these are nothing but a piece of wire with a fancy resistor like piece of plastic on them, they may even be big low value resistors with all markings removed and replaced with a outrageous price tag. Take my word for it.
Replacing the wiring will not do anything either, maybe measurable not nowhere near enough to justify the cost. this and above is a total 110% waste of money.
Anyone with any kinda knowlege in electronics would know this. Im suprised such snake oil products are even allowed to be discussed here.
However replacing electrolytic capacitors is almost a necessity if the amp is more than 5-10 years old, especially if its class A.

Wow thanks for the info, thank goodness I did not waste my money.
The reason I guess why they are allowed to be discussed here is so that you can chime in and tell me so.
Also any kind of knowledge in electronics is kind of exaggerating. Electronics is an extremely broad category. No drama needed.

I have replaced the caps on the signal stage of the XPA-1. It had sounder caps which I replaced with Sonicaps. There was a huge difference. I first replace the caps on one of the amps and played it (only the left channel) and then swapped the amp with the stock amp and played the same chanell (left only) and I could here the difference. This is without them being run in.
I have a lot of electronics experts saying it should not make a difference but it does. A lot of these are from people that call themselves experts but do not know enough.
There may be alot to gain but be sure you know what your doing or get someone who knows what they are doing to do the work. Disclamer - you do it at your own risk.

Unwanted mechanical Hum audible
a friend of me uses this amp. From the beginning he observe an unwanted hum resp. buzzing at certainly times. The hum doesn't comes from the speaker - it is a mechanical buzzing from the large toroidal transformer. Obviously there are DC components on the mains - go to

Who can upload schematic diagrams for power amp and information concerning brand name and model number of the main transformer itself?
Thank you very much in advance.
