Is yours upgraded with the new heat sink (or another heat sink) I had minor hissing with my 25ohm DT48, but the hiss is gone after arn replaced or added another heat sink. What makes me want to get another amp is the fact that I need to use a adapter with my 5 ohm headphones. I feel the added resistence ruins the sound for me a bit. My next amp will be the auditor, but now I'm saving up for the HD800 or OPPO83SE. I would get the upgrade. Arn told me the GP is finalized, so I expect no new upgrades.

I do not hear any hiss at all. Even with the version 3 the noise floor of my Headphone Pro-V is deadly quiet. And if you only hear hiss on one channel that I guess it is more like associated with cable joints and connections.

Glad everything went well. You had some reservations before. But what a sigh of relief. You got it and like the upgrades. I think the upgrades are worth more then arn charges.. Just between us. This amp deserves much more cred. What rule says a amp can only be considered a good bang for the buck only when it's 400 or less. This amp easily competes with other sub grand amps. Tis a shame. I also asked Arn for a balanced GP. I got no answer.

It also have already somewhat forward mids I feel. Liquid they are already. Some honey to it even. But then they do perform great unamped so should perhaps not be affected that much...

Pro 900 sometimes get a bit bright on the GHP. DX 1000 on the other hand have significantly rolled off treble Is the treble untouched with the upgrade? Bass on the DX 1000 does it protrude more into the mid range or is they just getting more lush then ever?

Do you preferr both with the upgraded version KeeS?
I didn't notice a change in the sound stage, one way or the other. Maybe it's headphones or ohm related.

When I bought it in january, Arn told me it was the latest version (v5). The problem is rellay annoying since I cannot listent to my new HF-2 with this amp ...

Not much. He said he would send me another wall adapter power supply in the next weeks. I told him I tried another power supply and it didn't change anything. I did not reply to me. Sadly, he's not been very resposive about that issue.

ugh.. Me & Arn sent a combined 60 emails to each other in a month.. On a side note, is the hiss there when the music plays? Can you live with the hiss?

Last week when Arn sent me an email (his survey on our listening volume) I told him again about my problem and he never replied ...

Yes, I can hear the hiss when the music play (at low volume). And no, I can't live with the hiss, it's really annoying.

I've just opened the amp and realised that there is a small nick on the sheath of a yellow cable that goes from the right channel RCA input to the stepped attenuator right channel (there is a ferrite cylinder on this cable). The inside wire is exposed. Could this be the cause of the hissing problem ?

ACTION

Could be I suppose. I have no hiss issues with any of my low impedance headphones... The ED 8 and DX 1000 is particularly sensitive so is the 435S as well so it should pick it up if it´s there.

You got it with your K702 as well? Didn´t got it with my K701 either and I am using a 220V/120V transformator which is not the purest way to power it I am sure.

Really hope Arn is ready soon with his power adapters so I can send my in for the upgrade. btw changing the volume pot so I get more notches to work with shouldn´t effect noise floor in any way?

Your amp is under warranty. He has to fix the problem. If it was me I'd keep emailing him, call him. I have his number or see him personally since his place of business is a 1/2 hr drive.

To be honest, Arn has not refused to repair the amp. But the proposed solution (replacing the wall power adapter) probably won't solve the problem. If it doesn't, I will have no choice but to send it back to him. There is no doubt in my mind that Arn will honor the warranty, i'm just saying is not very responsive when I ask him question about the potential cause of the problem.

If someone get news about the new power adapters being ready please shout here... I don´t want to mail bomb Arn to much.
post #283 of 357
Prototypes of the power adapters being available now. The amp is up to V6 as well. Will send mine in after the volcanoe have cooled down

hahaha, what a laughable sales department, I'm still giggling.

the guy first started telling me that I should bin my cd1k and buy a pro750 or a grado from him, and that he was selling the BEST headamp on earth...not one of the best, simply the "best evar"

when I said that I already had a burson ha-160 and was an old-timer on head-fi, he started to tone down ^^

then he said that his golden amp thingie was using a bunch of low cost OP825 opamps on an SMPS wallwart...and he suddenly started becoming arrogant and patronizing...what a joke company...I'd rather give money to charity at this point.

bottom line is: good luck getting your amp fixed buddy

That doesn't sound like Arn.. When I told him I was using 50 yr old headphones, he never recommended me any other headphone. As far as I know, he doesn't sell headphones, unless he changed his practice. The amp is VERY good.. You should hear one.. I place it above the HR2.. The Wall Wart does bother me.. & I personally think it's lame, but the sound is far from lame. Arn is true to his word.. He actually wanted to test the DT48 personally before selling me his amp when I told him it was 5 ohms.. He was overly cautious.. He replied to every email I sent him.. Over 30.. He is a stand up guy.. & stands by his product.. If Arn said he is selling the best amp ever then he is wrong.. Still doesn't sound like him.

To be honest, Arn has not refused to repair the amp.
