Pro vs. Consumer Equipment


One of the best set-ups I ever heard was a Crown preamp feeding a McIntosh amp driving a custom built cabinet featuring JBL professional speakers. I've also read quite a bit about professional cables being a lot less expensive and just as good as consumer cables. Earlier today, D911 posted a thread on the professional ART SL-1 power amp.

Across the board, these professional solutions seem to be very high quality at a much lower price point than the consumer equipment. So what's your experience? How many of you are running professional equipment in your set-ups? What are some great recommendations? Does this work better with some kinds of music than with others? Thanks in advance.

I am posting this in two places:
The way I look at this is that D911 has a financial interest on the line here and is really doing some major league bragging about is his modded amp. In and of itself no hurt to anyone. But on the other hand, whats the difference between this and every one of us who is about to sell a piece of gear using some "gimic" to start a thread saying how good it is. We would be swamped.

D911 started this game and should show his cards. It seems reasonable for him to send one of his modded units to an audiogon member who we all feel will give a impartial evaluation. In this way Don has one unit tied up in testing so there is no big financial anchor for him, unless it doesn't pass the test. But if it does, he benefits. If this works it can be benchmark for future self-promotions.
I had the modified DI/O, the first mod was done by the same gent that mod'ed Alberts. In all fairness, those mods really didn't make much of a difference. Mark's mods were elementary, like most of the mods that you read about on the various audiowebs. I'd sent my unit off to Kevin Morris (515) 288-8464, who redesigned the some of the circuits altogether. It has been too long since I'd had this done and can't elaborate on the entire series of mods done, (which is the only reason I included Kevin's phone number), but remember that one included adding a jack for an external clock. The sonic difference before and after Kevin's mods were dramatic, and sonically far superior to the unit you'd had, Albert. Syncing the external clock to both the transport and the DAC was a large sonic benefit, as you can imagine. The Kevin Morris modified unit is what Don had bought, so no clear comparison between yours and his could be determined. I know first hand, as I'd owned them both, (actually the same unit, but you understand).

I'm no longer using the DI/O, having moved onto another format. I'm one of the guys waiting for Ed Meitners DAC6, which should be delivered around 5 or 6 weeks from now. My brother Paul uses the eight channel Meitner DAC8 MK4, the latest pro version.

Kind regards,
Brian
I have no problem with this. I just need some way to track it. There are obviously people who form opionins about gear they have not yet heard on this site, I won't allow it to go to any of them. If someone suggests a way I can track the unit and hold the current holder of the unit financially responsable...I say lets go for it.

Regards,
Don
Brian, I too would like to hear the Meitner. I have had two or three independent listeners tell me it sounded wonderful. Please keep us posted.
Albert I know you prefer analog. I also know your system is completley optimized to make your LP playback sound decent. I am not surprised that you would say this. I have owned some very fine digital gear and to my ears (and to my dismay) the DIO beat the snot of everything I ever put against it. I don't know if you guys had stock or moded units (if moded, who did it...etc). Stock units are I admit hard sounding, hence the mod process, change the opamp, remove the tube, and voltage quadruppler, remove the back board with the coupling caps. remove the Voltage regu, remove some of the electrolytic caps, replace the steel pins with copper posts...etc. The unit still sounds better stock than most things out there.
However, I must add we all like what we like.
Regards,
Don
