This isn't meant as an insult. I've had friends and family members who haven't noticed any differences at all between components whereas some say the difference is "night and day". Lucky for the people that can't notice the difference as they can be happy with a ghetto blaster and save a ton of cash.
2. Their system is incapable of differentiation.
This could be due to a number issues. There are a lot of components between the source and the final sound heard by the listener and any can degrade the sound considerably.
The most common I've found is overly complex passive crossover networks which "filter" and degrade the sound sometimes rendering a very high quality source such as the Oppo to just "average". For example I have two systems. One is capable of taking full advantage of a very high quality source such as the Oppo 105 and the other is not. On the secondary system, the Oppo does sound a little better than some of the inferior dacs. On the main system, the differences are like "night and day". Also price has a sparse relationship to sound quality. I've heard a pair of $4000 single driver speakers sound much more "refined" than a pair of $180,000 speakers. So if you can't hear much difference between the Oppo and another DAC/squeezebox etc then don't blame the Oppo look elsewhere within the system...
Over the next few weeks, I'm going to do the following:
1. compare the Oppo to a variety of pre-amps in the $150-$15k range and decide whether the Oppo sounds better standalone or with a preamp.
2. Compare the Oppo to a variety of external DACs in the $500-$15k range to determine where the Oppo fits with differing priced dacs.
3. Compare a variety of amps with differing input impedance to determine whether it is a "true preamp". Despite the "theory" it should work, this needs real life testing as I've had mixed results in the past.
I hope other people post their comparisons on the above items as well so we can get a feel of where the 105 ranks in the grand scheme of things.
I've also found this unit needs quite a bit of burn in time. I've been burning this in 24/7 since I got it and it took a long time to settle down. Plugging it in on arrival and then firing off a review after an hour or so is doing this unit a disservice in my opinion.....
Hello, I just ordered a OPPO 105 today, and I am wondering something on this " Burn In".. I was a mechanic for 25 years, and the "breaking in" of an internal combustion engine had as much to do with heat cycles, as it did run time. So I ask,
1)Exactly what burns them in?
2) Just powering them on?
3) Or do they have to be playing material?
4)Do they have to be "cycled" to burn them in. Heat up, cool down,heat up, cool down etc.
5)Can you put a disk in them, put them on repeat and let them run for a week? Or will you get the same outcome just leaving them powered on.
