Darkvoice just released 332 - Page 98

post #1456 of 1888
WRT to modding I have some Nichicon 100v 220uF output caps sitting on my desk ready for next week

There are also some vibrapods on the way from the USA

As far as I know there has been no problems with excessive heat. The same cannot be said of the early X-CAN V3s. I had one, and the scorching around the transistors on the left hand side was really bad. It was, apparently, a technical flaw: mismatched transistors caused higher currents to well in one side of the amp. In later models, the problem was rectified.

Those 220uF caps should give you more scope in the way of headphones, Hawkhead. Pink Floyd at the Rock Grotto has experimented with these caps in the 336i with excellent results. He measured the DV amps: stock, they are suited only the high impedance cans, specifically above 250ohms. With the Nichicons fitted they are just about perfect for all headphones, but can drive lower impedances, including Grados at 30ohms.

I've Not Heard Of Any...

I've not heard of any overheating issues... but... I suppose you could always have some, with any amp that gets pretty warm, and in such a small case with tight fittings.

My actions were really taken as a precautionary measure - because I became obsessed with the heat being produced by the DV332. I suppose in some respects the warm case, really is "a good thing," because its evidence that the case is acting as a heat sink to draw off the heat from the components. But... I'm much less concerned, now that its totally "cool to the touch."

The only real disadvantage is the requirement that I make space for the small fan to blow on the amp - it would look much better and save some space, if I'd "jury-rig" the Radio Shack fan into a base for the amp, but... "maybe later" when I have a bit more ambition.

None of my X-CAN components ever got very warm to the touch - so, I was never very concerned about them.

Oh yes... the bottom plate just slips off after you've removed the ~10 small screws from the bottom (leaving the rubber feet connected). I suspect your plate may be stuck down by paint. If so, just run an Exacto knife around the plate in the crack between it and the case to loosen the bond and cut the paint so you don't inadvertently pull some of the paint off the outside of the case, when you remove the plate. When it's loose, it will lift right off very easily.

By The Way...

By the way... I doubt I'll ever become so ambitious as to "mod" my DV332, by replacing the POT, or Caps, or whatever.

But... its sound is so phenomenal... I really don't feel compelled to.

And my low impedance phones now sound great. The more I burn it and the rest of my components in... the more all my headphones sound fine with it... including all my low impedance phones. They've pretty well lost their "rough" sound, and of course the Senns are almost incomparable with it.

In this regard... the only thing, I'm not sure I fully understand - is why all my phones sound very similar with it - very slight differences in the sound between any of them.

Hi Godkin - small world - saw the 336 thread and got the caps from Pink Floyd

shall be posting for help no doubt!

I never understood or heard the "roughness" some talk about with Grado's on the 332. I like my RS-1's just as nice as the HD650's using it. Do you think senns (HD650) could be perceived as a bit smoother because of their more laidback, rolled off signature?

No...

No... actually... when I first got it... it sounded a bit "rough" with my RS-1s - particularly the upper mids, and sometimes the bass - sounded very much like clipping... a lot like my WA3 had sounded with them. And... my D5000s sounded somewhat the same with it.

However, as all these have accumulated more and more hours... it doesn't seem to be as rough as it was with these phones earlier. Though - amps with very low impedance output, do still sound smoother with these low impedance phones (e.g. X-CANv8, etc.).

No... but... there's very little point for me to do so... since... I intend to never spend that kind of money on any single piece of headphone equipment. I prefer to be able to sell my stuff, in a day, or two, with the greatest loss, I might incur limited to about $50... not hundred$, or thousand$.

"Not gonna do it... just... not gonna do it."

I see, that is a good plan. The reason I ask, is because I have one on order, Lot of people say the HD650 sounds just magnificent with the 332, so I am wondering how big of a difference there actually is between those amps.
Don't want my expectations to go through the roof while I am waiting, so I kind of prepare for the "worst", but hope for the best if you see what I mean.

They do sound pretty good with the DV332. I had the "old" version of the HD650s, and they sounded pretty good with it - but, I still preferred the "new" HD580/600s.

I'm sure they'll sound great with the Zana Deau - I'm sure someone has that combo, that can tell you. I would think they'd sound better with it than the DV332.

Maybe this is a good thing, as it will diminish the need to own more than one headphones, since there is no real difference in their sound with this amp anyway.

By the way, how good is DV332 compared with Mad Ear Purist Maple Tree? My friend is considering getting one of these amps to use with his Senn600 and AKG701. ATM he gravitates toward Maple as it's more expensive and seems to be in higher class. I don't have any idea about how it sounds, so I ask you guys.

I can't tell you... perhaps someone else has compared them.

I Don't Know...

I listen to all you folks describe the sonic differences from one set of tubes to another... as if... there are pretty significant differences.

But... I don't know... I just must "have a tin ear" - I have a very difficult time discerning significant differences in any of the tubes, I just rolled through my DV332.

I just rolled through various 6AK5/8100/5654/etc. tubes: Tung Sols, Mullard/Phillips, RCAs, and Sylvanias... and... I can tell only very minor differences in any of them - certainly <5%. All these matched with my Svet 6C19V-EBs (whatever).

Some may have very slightly more... detail, or air, or soundstage, or mids, or bass, or impact... but... very, very, very slightly - not enough "to fret over."

They all sound... absolutely incredible... in the DV332, with my HD580/600s, or any of my phones, with my SA-8001 as the source.

I don't know what my problem is... but... perhaps, I'm not the best one to tell anyone, what the sonic differences are in anything.

But... this entire set up is pretty phenomenal, whatever tubes!

Which is a damn good reason... I shouldn't be spending any more money... to upgrade anything - I just can't tell the difference!

Is it possible you might have some upper frequency hearing loss? I only ask this because it is one of those things that you don't notice, and it can happen over a long stretch of time, like several years. My wife (we found out) has some higher frequency loss, plus a little tinnitus (ringing) too. She had no idea anything had happened. No obvious things anyway, like an explosion or fast pressure changes and the like.
