I see the price of some of these mods, and they seem disproportionate. 1500 dollar mods for 800 dollar amps? 750 dollar mod for $200 receivers?
Very true. And as a Bolder modded Panny XR45 owner I brought this up a bit in a follow-up review I did after about a month of break in.
On one hand it's a rip off because you get so little added 'product' for such a huge amount of dough. I mean in the end it's still mostly the same Panny boards, chips, etc...
On the other hand it's hand done work nad putting in first class parts that just isn't an option from an say high end company making a TOP quality version of the same Panny (which is something I'd like to see actually. Maybe a company like Outlaw Audio -someday).
The end result like dave_c mentioned is a unit that eliminates a slew of analog connections. You could say it's a powered DAC and there aren't any amps, preamp, etc... rather than saying you're getting all these things in one unit.
This is of course what the stock unit is in the first place though.
I really think there's some really awful parts/quality in the stock design and the modded unit fixes a top end that IMO HAD to be fixed for it to be a 'keeper' for me.
The end result is also a total cost FAR less than any combo of even high quality/high value amps, pre/pro,IC's, etc...
I don't think modding these things is the BEST thing to do but for now I think it's a great option.
I'd love to see quality/value companies like Rotel/NAD/Outlaw ect... leap frog the megabuck high end and put out a Rec. based in these TI Equibit boards that does all the tricks of a top pre/pro and has a power supply that's really well done.
I think then mods might make it even better but probably not that worth it for the cost of cracking it open and replaceing real good parts for a little better ones by hand.
All the Pannies seem to really be are crappy cheapo recs. with TI's whole Equibit board tacked on... but that seems to be mostly enough.
I'm not sure about power supply. Lots of people seem to hate switching PS's but they can charge a lot better than torroids so maybe a small combo of both. You could use a couple real small torroids. Great quality, but still cheap.
