I already had the partsexpress powersupply in my shop.  It is a useful unit since you can select various DC voltages for powering all kinds of things.  So no extra cost for me.

 

But anyway, let me take this opportunity to thank you leeperry for your review of the Bravo.  This thread is what caused me to purchase the bravo and it has been a very nice addition to my listening experience.

So tune it for 24VDC and feed the Bravo? It can't be worse than the cheapo wallwart IMHO.

 

I'll soon be trying this cable between the Supplier and Bravo, it supposedly sounds amazing: http://cgi.ebay.com/Teralink-X2-X1-Power-Supply-A-B-4N-Silver-DC-Cable-/260821238875

 

You're welcome, the Bravo is a very nice piece of kit...as a combo w/ the Supplier, the SQ/price ratio is excellent.

Heh thanks for that LP, I just pulled the trigger on that Teralink cable for my Supplier>Bravo. It should be a good compliment for the cheapo silver USB cable I am using to feed it. I suppose the weakish link now is the Blue Jeans coax cable coming out but it's competent.

 

BTW, I will be selling a Supplier soon along with their USB I/O converter, but I could probably be persuaded to sell it separately if the price was right.

I had sent an email to firestone tech support on their guidance on the supplier with the Bravo.  They indicated that the supplier would not be a noticeable upgrade for the bravo.

 

What are your thoughts and experiences on upgrading the bravo with the supplier.

 

LP, the partsexpress linear power supply that I have maxes out at 12 VDC.  So it cannot support driving the bravo at 24 VDC.

Good! I hope you won't mind being my guinea pig, as I'm highly dubious about power cables but I'd be very glad to be proven wrong. OTOH, I tried 99% silver and mundorf silver/gold for coax, and it sounded plain bad.

Kingwa says the exact same thing about the DI PSU, I guess honest sellers prefer to miss a sale than having customers whining about audiophool tweaks. Maybe grokit can share his thoughts on the Bravo+Supplier combo? IME, the Supplier is a major improvement on all Firestone units...as we're essentially listening to the PSU. OTOH, toslink should be avoided IMHO..check out how nasty it can look: http://lampizator.eu/LAMPIZATOR/TRANSPORT/CD_transport_DIY.html

 

You can see hiface tweaks based on batteries and everyone raving about them, we're lucky that Firestone offer a linear regulated PSU so we don't have to cope w/ kludges. If you're DIY savvy, the TREAD would provide even lower ripple. This said, I rest my case that the Supplier is a far better investment than the ADuM dongle+WW cable.

Hmm... that's interesting. I feel that something as potentially sensitive as an outboard digital word-clocking device deserves as much electrical isolation as it can get.

For under $10 shipped I figured WTH, so we shall see.

Do you know anything about this one? They don't even list the length (looks to be 1M), much less what kind of wire is used.

I've always used the Supplier with the Bravo, but when I am checking out that power cable I will also try taking the Supplier out of the loop and see if I can discern any audible differences.

 

X2, I did notice a difference when I added it to their USB I/O.

Cheap Audioquest from China = 99.999999% fake. Try a male/male RCA adapter insteadpopcorn.gif

OK, I've ordered two silver DC power cables for the Spitfire and Bravo....we'll seedeadhorse.gif

 Has any one made a comparison between , audio GD DI and the Bravo ? (eventually a EMU 404 PCI-E) (coax output) don't like optical rolleyes.gif

I like the fact that the Bravo has the Supplier PSU available, OTOH the AGD DI can go 192k in certain situations?

 

"With USB and optional coaxial input (Support up to 24bit/96KHz)
RCA and BNC coaxial output (Supports Original sampling and upsampling to 96KHz/192KHz)"

 

I'm not sure I really understand, I think it means USB is limited to 96k input?

Well Audio GD DI also have PSU upgrade 

 

Both use a  TENOR - TE0722 as USB receiver chip .

 

But after is not the same way ... Bravo use " Reclock : Include Fi-reclock® technology to reduce jitter" what is that ? don't know ... and after transmiter chip WM8804

 

Audio GD DI use a " d DSP3 are based on the Altera Cyclone II chip, " that can do upsampling job up to 192khz (via a jumper or something) you can set it to no upsample .

 

(Well just reading audio GD and firestone page ...) .

 

usb himself is limited to 96 khz (Tenor chip ...) but you can do upsamling if you want like i said .

 

 

Well i only want to know wich is better :p

OK, just got mines and installed them on both the Bravo & Spitfire MK1! At first, I thought the SQ was very different, then not so much....I'm listening really carefully now, and I'd swear that the SS has become wider and deeper and the trebles far less congested. Need to listen even more carefully now...it's clearly not a night & day, but it might have improved my headphonic experience altogether indeed...but I think it's also made inferior quality recordings even uglier to listen to now[:festen]

 

For instance in this tune, the tambourine is much clearer and far less mushy: http://www.amazon.co.uk/gp/product/B002JH93BO/ref=dm_mu_dp_trk25

 

But we all know how silver can often sound overbright and become tiring after a while...so I'm still torn atm. More impressions later, and let us about your experience too [:icon12]

 

PS: I've A/B'ed several times, it does increase the SS volume and top-end clarity but at the expense of transients I think..the sound is far less punchy and appears very much dull to my ears, and the SS being so widened doesn't make any sense anymore. This OST is heart-shredding w/ the stock copper DC cables(+ferrites), and dull to the utmost w/ those snake oil silver cables...needless to say that I've learned my lesson.

 

PPS: I've also tried to swap only one cable at once, but it always sounds exactly the same as both cables together duh...plasticky and lacking emotions. Silver has nothing to do w/ audio IME, as my tests w/ silver/gold coax were a major fiasco as well.

Mine got swapped in the other night, it's obviously a better quality cable physically than stock but who knows about the wire really. I feel like I got my $10 worth, meh. It is what it is.

no SQ diff? even in quick A/B? still over Toslink?

post #525 of 542

 

I don't know, maybe. I don't really trust myself in situations like this as far as placebo goes, yet I have no desire to conduct a proper DBT.

 

Currently going with a cheap stranded silver USB cable direct from my Mac to the Bravo with a Bluejeans coaxial cable into the Mini-i, upsampling Redbook to 96 k with PureMusic.
