External HD VS Flash Drive Sound Quality Question


Hi have an Oppo BDP-95. I am up to around 25 Flash drives which is getting ridiculous.

2 questions (hoping for folks who know the definitive answers; I have my own guesses, bu that's all they are.)

1. HD Tracks has written that the Flash drives sound better than any spinning disc or drive due to lack of jitter from lack of a spinning disc. Is that accurate?

2. I have noticed a new generation of external hd's that get all there power through the USB port, & do not require an out board power supply.

A. Would there be any detectable sonic difference either way? If so, which is better: the cheap wall wort power supplies or getting power solely through the USB line?

B. The Western Digital USB drives with no power supply have a proprietary cable that looks quite cheap. Would the lack of an audiophile USB cable be sonically problematic?

I'm basically trying to decide whether to ditch the lash drives or a USB hard drive; & if so whether to go with a powered or unpowered drive. A couple +'s re the new WD's: they are teeny & they run cooler than the Seagates I've used.

It's been a bit frustrating how long it's taking me to do a series of comparisons. Combination of life, & I'm also a movie fan. While my main system is optimized for music (& is stereo, NOT 5.1); I also use it for film. For the sake of these comparisons, system is stock Oppo BDP-95 with an after market power cord that I don't currently remember the name of (it was recommended her), connected by Tara Pandora to a Mod Squad Line Drive Deluxe (same electronics are the first McCormick model), which is connected by Tara Analog standard to a McCormick DNA 1 Mod 12 (mod done by Conrad Johnson); connected by Tara Omni bi wired speaker wire to a pair of NHT 2.5 I's (IMO the system's weak point).

Did another brief comparison tonight; the 1st 2 tracks from Peter Gebriel's Scratch My back (Heroes & Boy In The Bubble) in 24/48.

Tonight I intentionally played them through the Seagate first. Sounded quite nice; I was thinking there was no way the Flash drive would be better.

I was wrong. The Adata Flash had a slightly bette sense of midrange liquidity, sound staging & air.

I'm still not finished; but am continuing to come to the conclusion that the HD is much more convienient; and that in my system the Adata (which I've done all comparisons on so far) is slightly better.

As the weak point in my system (imo) is a lack of detail in the NHT's, I'm guessing in a system with a higher level of resolution the differences would be more pronounced.

I'm still not feeling this is definitive, though.

For times where listening isn't the #1 focus, if it wasn't for the bloody 1-2 second gap the Oppo's flac decoder puts between tracks (wav's also), I would probably be ripping & selling most of my cd's. The HD is certainly good enough for 99% of 44/16 cd's. Of course an option is to edit certain tracks together, but there is only so much time in this life!

One other issue with that idea; as far as I can tell, with 44/16 the Oppo only sees HDCD on real discs, not in files (again both flac & wav).
A question: When you change between listening to the flash drive and the external hard drive are you removing one and then connecting the other to the same USB connector? Or do you have one always connected to the rear panel USB connector, and the other connected to the front panel USB connector? If the latter, when you reach a more definitive conclusion I would suggest that you reverse which connector is used for which drive, and see if the same results still occur.

Yes, both are connected to the front jack. The back is used for the hardware region free hack.
I can sympathize Moomoo. Doing these kind of comparisons is a pain in the butt. I do appreciate your sharing your findings with us.
I apologize that I've neglected this thread & the testing. I just haven't had the time to do it thoroughly; while I live in a house my neighbors are quite close & the best time for me is late night when I can't crank it up because of the neighbors.

That said, my current INCOMPLETE conclusion is that for unknown reasons the Flash Drives do sound a bit better than the hard drive; though 96/24 on the Hard Drive still beats the heck out of 44/16 on a cd.

For specifics please see my earlier posts. I will still try to flesh this out eventually.

On the other hand, i am starting to see Flash Drive quality go downhill; especially Lexar which used to be my go to brand. I've had 3 recent manufacture Lexars fail in the last month; & the latest I bought a series new to me called the S23 is the flimsiest Flash drive I have ever seen, though so far it works perfectly.

So far I've never had a bad Adata, nor a bad Sandisk (other than 2 obvious Chinese counterfeit Sandisks I bought on Ioffer). I own around 50 Flash drives; the only total failures have been the 3 Lexars, the 2 fake Sandisks & a no name 64 gb drive that a friend loaned me last year. I've also found HP to be very flaky, but never had a total failure.

I do practice redundant backups on all hi-res music just to make sure. Most of my hi res stuff is on either disc or Flash; + 2-3 external hard drives in addition.
