Help needed with LD mkV and low impedance headphones - Page 5

I was suprised how much the volume played a roll in the bass. Never really noticed such a dramatic change with my set up..But straight from the comp.. Really noticeable. I might burn the song onto a disc & play it on my set up to get a better picture & better idea of the bass.. I know the roll off was pretty significant with my modern DT48, so, yeah, probably more so with the vintage.. You really need to go to meets & get a 100/120 ohm adapter.. That ohm seems to work best for the DT48's bass.. Least holds true for the DT48 8ohm I bought from Nikon..

If you listened with my set up I think you would find the roll off pretty severe...certainly it's so compared to the v6 and the dt250. I really do miss the lower bass with a lot of tunes, but with others not so much. I still enjoy the way they do vocals. Nat and Natalie Cole sound unbelievable with the dt48...and John Lennon, Norah Jones, Frank Sinatra to name a few others. Maybe because they were designed originally for accuracy with spoken word?? Well they really DO sound accurate to my ears, FWIW. Hopefully shamu will have a listen and let us know if there's severe roll off with the Lavry. Glad you liked the tune!
 

With my Foobar->optical->custom DAC/AMP->DT48, the two 5 sec hits definitely sound bassy.  The hits throughout don't have a ton of impact, but they are definitely there and deep enough.

Hi lejaz, can I suggest something different?

With your amp (and I use to own it) I would use a HD650: OK, they're not dead neutral, at all, but you have already a pair of 2 good flat headphones (AKGs). The HD650 are funny, highly involving, and not bass light :-D And they're a very good match with the MKV

IMHO, they're a good choice with jazz, because of their warm and 'smoky' attitude.

I wouldn't call the 70# flat..

If you can get better bass out of the DT48 I see you selling your 702, not a slight against the 702, but my opinion.. I did like the 701 by the way.. The 650 mid range is also very good but in the opposite direction.. Warm, rich, full, & I'd put emotionally inclined to seduce the listener.. The 340 does this even better IMO..

I would love to hear the 650's one day, but for now I am pretty infatuated with the way the dt48 does the midrange and don't want to part with them. I just love the way they put such a clear focused lens on the mids. I may sell the 702 one day, and if I do I might like to try one of the sennheiser 6XX's. For now I'll probably look for a better amp for the dt48 that won't break my budget.

Hi lejaz, can you tell me where to order a transformer based impedance adapter from: using DT48e 200 ohm with LDMKIII - thank you.

200r is not low impedance. it is high impedance.

Cinemag, jensen, sowter, and edcor all make 600:150ohm transformers or transformers that can be wired as such VERY easily. With a 600ohm (or so, tune to taste) resistor in parallel with the 200ohm cans it should be about right. 

Its still not going to change the sound of the headphones.

Edited:

This question came to me after this thread slowed down:

For the question that is more or less the topic of this thread (is the LD-V adequate for driving low impedance headphones?) were the headphones used with the 300 ohm cable or not? If they were generally used with the 300ohm cable, the LD-V was driving ~300 ohms, which is certainly a high impedance. It is very rare for people with sennheiser HD600/650/800 to complain that the LD-V cant drive them.

Yes, but even if the LD mkV should drive easily a 200 ohms loads, the DT48 were designed with a 120 ohms source impedance in mind. So adding an impedance adapter should bring the sound closer to what it was originally intended.

I would bet that Lundahl also makes a suitable transformer.

If you ask electraprint nicely he probably would too.

If you asked really nicely Edcor or Electraprint would probably wind 600:200ohm transformers.
