Audio-Technica AT-HA5000 vs. Higher Fidelity HA-01 (photos) - Page 6

post #76 of 126
well, you never know how the oversampling in your computer works. Maybe it's also altering the signal somehow. It's also probably not a mere oversampling, but I guess it also expands the resolution to 24 Bit and there are also different ways to do this...

Anyway, the description of the buttons on aqvox is really misleading. For example, the PCM1706 DAC is even not capable of doing 128fs delta-sigma oversampling with 192kHz signal, it's out of specs and not supported, but the button is still there and you can perfectly switch it on together with upsampling...

Ok, this becomes really OT. Back to W5000, I believe it really shines with a tube amp. It was a bit bright and sterile with every SS source. Also this headphone responds very good to tube rolling. With my amp I can change the signature from almost SS-like (EH 6922) to a very pleasing warm sound (with very cheap NOS Philips pcc88). I think W5000 really neads a bit of warmth, as it is on a bright side of neutral, especially evident with vocals, which tend to sound thin with SS gear.

My ss gear sounds better than your ss gear....

Well did you listen using the AT-HA5000? It is SS and uses the MOSFET transitors to effect somewhat the sound of tubes as I understand it.

You are most likely right in general terms for most ss gear vs tube gear with the W5000s.

sure, I don't doubt that HA5000 sounds very good with W5000, it has been designed for it. But, since most people reported that HA5000 sounds not that good with other headphoenes, I don't believe HA5000 is a neutral SS amp.

My point is - most SS amps are neutral by their nature, but W5000 requires a bit 'sounded' or EQed amp. That's why a tube amp is just perfect for this headphone - you can EQ it with tubes, just to a degree which sounds good to you.

I had hoped to inject a bit of humor on that post.

I agree with you completely in the the HA5000 is probably not for the general purpose headphone. But for the W5000......

I have one link where they apparently do use the HA5000 for their reviews and have used it with several of the more favored headphones around here.

I think the AT-HA5000 works very well with the AD2000, W2002, SA5000, RS-1, MS2i and HF-1 besides the W5000.

@slwiser

don't worry, I've got it If it appears other way - this is due to a language barrier

Well, W5000 is on a bright side and hence HA5000 sounds good with bright low-impedance headphones. My CD3000 sounds very good exactly with the same tubes as W5000 does and I don't like both on regular ss gear.

I don't think the W5000 is particularly sensitive or especially prone to picking up hum/buzz.

Using the AT-HA5000, Lehmann Black Cube Linear (low gain setting) and RSA Raptor, there is no hum/buzz or any kind of noise from the W5000. Black background only. Using the Hornet (low gain setting), a hum appears after the third to the last volume mark, nearing 3 o'clock on the volume knob; otherwise, black background.

I don't use the W5000 with the Dared MP-5 because of a high level of noise. The Dared is very high gain and basically a speaker amp.
I can hear the onset of hiss from about 10 o'clock on my Sugden Headmaster which is interesting. No hum or anything else though. All the other cans I have owned were dead silent up to the maximum level. Saying that, listening past 9 oclock for any length of time would give me hearing damage due to the SPL generated at this setting!

I am still burning my W5000 in. There is no question that it is a very revealing can with no veil whatsoever. And bass is certainly there (e.g. Kraftwerk Tour De France Soundtracks). But right now I can't get past the fatiguing mids. If these will smooth out to what I'm used to elsewhere it will be a really great can.

This HA-01 amp really interests me but it is obviously flawed. I would also consider the HA5000 but not sure if the SQ will be affected by using a step-up transformer.

Elephas - did you get a chance to listen to the HM with the W5000 as I have seen you mention it in one or two of your postings?

I'm now way past the new toy syndrome.
Satisfied for the first time, just me and the music.
They don't stop to amaze me, multiple eargasms every night.
A matching amp and source, and I'm done with head-fi as far as arguments and endless blah and FOTMs are concerned.
Well, there still will be the music subforum and the members lounge.

Now that I found love, what am I gonna do with it?
Wow, it's great to read how much you enjoy the W5000 as well. Coming from a crazy meet yesterday, with most of the great headphones ever made, I am still very happy with them, as I heard nothing headphone-wise that does quite what the W5000 does for me. Some do make other interesting sounds, but I don't know that any of suit my listening habits quite as well.

Maybe it's more a question of sensitivity than of impedance.

Unfortunately I fell in love with these noise detectors and now I need a new DAC as good sounding as the Aqvox and a low gain or even unity gain matching amp.Oh my wallet.
Isn't it amazing just how sensative these headphones are? They immediately found a hum in my former amp that I had no idea was there before. Then I spent all afternoon rewiring it with shielded cables to keep the transformer hum out. Low gain is mandatory for the W5000. Good luck finding the particular sound of the Aqvox in another DAC, it had a very certain and unique fun flavor. Perhaps just a low-gain, low-noise amp will be enough too keep the Aqvox's noise out of the way? Certainly that's the route I'd try first.

Some time ago IronDreamer started a thread about a contest of several DACs, including mini meet and huge meet impressions of lots of members.
To cut it short : They've found that the SQ benefits from bypassing the sample rate conversion function, but only in case the signal from the transport is of high quality and is oversampled before entering the DAC.
I didn't understand why outside oversampling should make a difference, but I did have the means to replicate the configuration since I did utilize the same soundcard/software as IronDreamer anyway.
It seems to sound better this way.I've never prooved it by a DBT though.
The Aqvox I found to sound better with the upsampling turned off, period. It did not matter if the transport was great or not, or whether you upsampled in the computer (though you could if you wanted to). The funky midrange coloration that the 192kHz upsampling of the Aqvox imposed simply stuck out like a sore tumb and could not be ignored, once I knew it was there. So it was bypass or nothing for me.

Mark,
your are always invited to drop by my house and try my W5000 fully burnt in with several amps: Lavry, OM and Supra XLR.
To me the mids of the W5000 are unsurpassed and certainly no fatigue at all: I listen to them for 6/7 hours in a row daily at work (plus another 3/4 hours at home).
And don't forget to bring around the Sugden as I am interested in trying it

Hi Iron,
this are quotes from two posts by myself in another thread:

"now, with my Supra XLR my W5000 perform so well that I am getting rid of all the other cans I have (SA5000, k701, K1000 and maybe HD650) because I just find the W5000 to be in a totally different league; I also have a pair of L3000 on the way, let's see.

One thing I am learning more and more in this hobby is that we all hear things differently: if it was for me, all other manufacturers could go out of business, as I find the W5000 so far ahead of all other that I just have no need to keep them.
The funny thing is that I have spent a lot of money for a balanced amp (and a great one) and I probably am going to use it only single ended, because the W5000 single ended sound so much better than the HD650 balanced.
Well, I believe I am keeping the HD650 for a while in order to have a pair of balanced phones, but I don't think for very long."

"I have been thinking all day about asking Iron Dreamer to balance a pair of W5000 for me. Maybe I will do it (I don't know if he will accept), although the problem of sending back and forth a pair of headphones with Her Majesty's custom lurking is not very appealing. Anyway it will be a second pair of W5000, as the one I have I use them for work and have to stay single ended. Also I am waiting to see about the L3000 before deciding"

Do you think it can be done?

No, I only tried a demo Sugden HeadMaster with the W2002 and L3000.

Seeing some photos of the HM's internals, I was surprised how little parts there were. It sounded good driving the AT's, but I didn't think it was better than the AT-HA5000.

I had similar experience with the AT-HA2002 vs. the Headmaster, and thought the HA2002 sounds quite a good bit better than the Headmaster driving the W2002, and W5000.

Well i was a little bored today so i had to take a look inside the HA01

It sports all nichicon caps, a pair of 2SC5200/2SA1943 Toshiba transistors per channel (seems to be a popular combo), an ALPS pot, takamisawa relays and some interesting jumpers and trimmers close to the OPAs or whatever it is under those 2 "do not remove!" plates
Overall it looks very clean and actually somewhat pretty Would be nice to have a transparent housing similar to the AT-HA20
