The bass is also a bit more muffled or undefined. Back in the drawer they go.

Anyway, it's subtle differences, and hard when not directly A/B testing. I think they are all excellent tubes, but I prefer the Mullards or the Ericssons, leaning towards the latter.
How coincidental! At the moment I'm also listening to Norah Jones through 403Bs. About the muffled and undefined bass, I agree with you as I also have that impression with 403A and 403B.

However, when comparing 403A/B and M8100, I tend to like 403 more. IMO mid-high range of 403 is very good, and the difference is very clear when listening to audiophile records (especially Susan Wong and other vocal-heavy record).

Actually, I know someone who could do this for me, but I don't want to just send the amp to him and let him do the experiment like it being a guinea pig. I think it'd be better to adapt some proved upgrade.

WRT to upgrades does anyone have any internal pics ?

I know of changing the output caps on a 336 to suit lower impedance 'phones

Also I agree on the Ericsson 403's these are my favourites too

About internal Pic you requested, as I'm using the amp right now and don't want to flip it over to take an internal shot, I will quote Budgetphile's post again as he posted the internal pic long time ago.

I wonder what kind of performance it can deliver if all interior components are changed to the higher quality ones. I may end up having a completely different amp.

Thanks guys.

I think I'll pick up a pair of Sextett's if I see some on eBay. Hopefully middle production ones appear.

As far as I'm aware, nobody has modded the 332 yet. Pink Floyd over at the Rock Grotto has modded a number of 336is to better suit lower impedance cans by removing the film caps and replacing them with larger value electrolytics; he has also changed the large power resistors with good sonic benefits. As a man with high impedance HD580s and HD650s upping the capitiance in the output stage would not be high on my list of priorities when modding the 332, but maybe a better quality cap would be in order - maybe a Clarity Cap or something. Also that nasty pot would have to go - a stepped attenuator would be nice, if it would fit.

W/r/t leaving tube amps on overnight, I don't think it's a good idea. It would in all likelihood be just fine, but if something did go wrong, it could result in a fire.

Little dot MKIVse or darkvoice 332?
post #1373 of 1888
I own DV332 for several months, and to tell you guys the truth, I'm not satisfied with its performance.

The combo is DV332 + HD650 (stock cable). I tried several tubes, namely WE403B, WE403A, Mullard EF95/M8100/6AK5W, and Sylvania 5654s. Some of these tubes sound better than the others. I myself prefer 403A/B for its clarity and treble, but there is one problem I always encounter regardless of what tubes being used. That problem is bass quality. I'm not a bass head, but I can't stand bloated bass. None of the above tubes can deliver a tight/fast/ and deep bass, as all I experienced so far is bloated and shallow bass.

My source is Rotel RCD06, which is known for its impact, speed, and clarity.

FYI, my power tube is Ulyanovsk, as I couldn't find any Svetlana.

I don't know why it's this difficult to bring out good bass as every component seems to be fine (I mean decent quality).

Is it possible that my headphones is defective or something?

That's Unfortunate...

That's unfortunate... the Svets and the Tung Sols produce the tightest, most extended bass, with the best dynamics.

It's too bad... they're both hard to find.

I know how you feel,
I wasn't impressed.
I liked my HD650's better from my dad's Behringer headphone distributer/amp that he uses in his recording studio (4 outputs-$200, source was Presonus central station)

Ummm, maybe it's time to consider finding some Svets on eBay and hope that the tubes shipped are actually Svets, not Ulys.

But you know what, I think I'm starting to get tired finding the way to bring out the best of HD650. I mean, seriously, how much should it take until I can make this phones sound good. I even tried swapping interconnect cable (even nordost, the price of which is even more expensive than the amp itself, I borrowed from a friend couldn't remedy that bass problem), AC cable (JPS red-wall with Wattgate on each end). Though the interconnect and AC cable aren't mine, I feel very frustrated jumping through all these hoops trying to make these phones sound "right" (and my expectation isn't even high).

I'm sorry if this post might seem a bit off-topic, but I think it's not the amp that is weak as almost everyone here seem to like it a lot. That brings back my last question, is it possible that my cans are defective? I know it sounds silly, but I'm really out of idea now.
post #1377 of 1888
It may well be you just don't really like the HD650. That was the conclusion I came to a few years ago.

I certainly think before you abandon an amp, it's a good idea to try multiple headphones.
post #1378 of 1888
Maybe the HD650 just aren't your cup of tea. Many report dissatisfaction with the sound until they go balanced. Obviously, there are great cost increases with doing so.

I have a stock HD650 with DV332 with Svets and WE403b and really love the sound. Would I love it more if they were balanced? Likely, but I can't afford it.

On the other hand, after awhile I didn't like the sound out of my Beyer DT990. I could have swapped amps and everything, trying to make it something it wasn't (to my ears). Or I could have made the switch to the Senns, which I did.

Have you tried Grados? They seem the polar opposite of Senns. If you're really into bass, how about the Beyer DT990 or a pair of Darthed DT770?

Sometimes the simplest solution is the best. Good luck.
post #1379 of 1888

Agree...

I have to agree.

While my "old" version HD650s sounded much better with my DV332 (and Monarchy M24 DAC) - they still seemed a bit slow and dark to me. And.. yes... the Aphex 204 sound processor almost turned them into HD580/600s, or RS-1s for me. But... I ultimately... determined the "new" version HD580/600s just sounded better... more alive!

And... the Svets and the Tung Sols in the DV332 help a lot... but... they won't make the HD650s sound like HD580/600s, or Grados, or AD2000s.

And... I don't know whether the "new" version of the HD650s will sound much better - haven't tried them, yet.

But... a lot of folks have come to the same conclusion - its just a lot simpler to swap the phones.

Thanks for the suggestion.

Actually, before buying I had auditioned Grado MS2 and Ergo Model 2 (driven by DV332/w stock tubes); HD650 and AKG 701 (driven by Lisa3). At the time, I was only able to use my iPod Nano3g as a source.

MS2 was ridiculously bright with DV332, and I'm not a fan of bright phones, so MS2 was out of my list. Ergo 2's sound was very close to those of 650, but I found 650 was more "fun" to listen to.

Unfortunately, the shop where I auditioned 650 and 701 didn't have DV, so I had to use Lisa to drive them instead (the shop also carried Tomahawk and Hornet, and I tried them all and found that Lisa3 was superior to those amps). 701, to me, sounded too distance and sometimes its treble can hurt my ears (note that I don't know how good is the synergy between Lisa3 and 701), whilst 650 sounded more weighty and more dynamic. Considering the kind of music I'm listen to (Jazz, Acoustic, Blues and Country), I picked 650.

The reason I bought DV332 was because it's said that DV332 + HD650 was a match made in heaven and I thought that at the moment with that amount of money, I couldn't find any better amp for my phones.

That said, after many hours of serious and analytical audition, I started to doubt if the sound I listened was the sound of Sennheiser's flagship phones driven by one of the amp said to be its best match.

Honestly, I'm really new to the headphone world and have no idea about how much I can expect from a good set of headphones. IMO my Totem Rainmaker driven by NAD C372 can deliver far better sonic experience.

Again, I'm sorry if my long; off-topic post upset someone.

P.s. A pair of (bloody expensive) Lm Ericsson 403Bs is on its way. I will see if it can make me love this set.
