How much are you asking for those?   Quote:  

I found that stash tin on ebay, however it would ship from Korea...   Your little amp looks amazing, I wish I could do that kind of DIY. I'm thinking about getting a cMoy for my HD 238s but I don't know how much they will benefit from the amp.   Quote: If anyone is interested...

Rergarding the linear power supply, is the LPS-1U-192K out of stock? I was looking at the Nuforce eStore and I noticed that only the LPS-1 is available, when will the other models be back in stock?

Is that a cMoy? Where did you get that case? it's pretty cool.   Quote:  

Wow, that's just too much. That makes me feel better about the $414 that I paid.   BTW, how do you think the HDJ-2000 would fit as a portable headphone?     Quote:  

Thanks for the reply. I know what that feels, I paid $414 for a pair HD 650s last year and now they sell on Amazon for $336.   Quote:  

This is a great review, very interesting read. You mentioned that there are tons of fake HDJ-2000s, well I found them in Amazon for $239 sold by Beach Camera. Do you (or anyone else) know that store? The pricing seems great since other stores sell it at a higher price, but I don't want to buy...

  Quote: Where did you get an HDP for 200$? Could you share your impressions with the HDP+k701, HD650 and 990 PRO? Thank you

I've seen the new PSUs in the Nuforce website, but not on the Nuforce eStore. I'd really like to know your impressions with the linear psu since you already know the HDP with the Sigma 11.   Quote:  

You could read Heaphone Addict's review and updates in the original post, very interesting though. I wouldn't recommend burning in without the headphones plugged since the HDP wouldn't drive any headphones and the amp section wouldn't be used, but that's just my opinion.   Quote:  

Just read some of the latest posts, Sid-Fi and Headphone Addict reviewed the HDP with the Sigma 11 PSU   Quote:  

When will the LPS-1 be available in the website?   Quote:  

  OMG! i cant' believe this! lol I really wanted your Sigma 11! I was going to tell you as a joke to sell it to me someday... and look what happened. I didn't visit Head-Fi for a few weeks and I lost a huge opportunity lol. Anyway, thanks for sharing your impressions, I think I'll get the...

Thanks a lot for sharing your impressions, I was looking forward for them since I was really curious about how the HDP would improve with the Sigma 11. I just have one question, how much did the total power upgrade cost you? And one more thing, have you tried the power conditioning?   Quote:

I believe that's normal since the same thing happens with my HDP, however, I noticed that the hissing disappears once you disconnect the usb or coax cable, that's why I'd like to try the HDP with an optical cable. Quote:

Thanks for the answer, I forgot to mention.

Well, that's what I want to avoid. I'll try getting an optical cable and check if that solves the issue. If that doesn't work I'll see what else comes to mind, maybe upgrading the PSU or adding some extra shielding to the sound card. If nothing works, I'll just decrease my source volume. lol  ...

Noob question: Is it possible to use passive speakers connected to the HDP's pre-out? 

I've had my HDP for about 3 weeks now, I'm using the coax out from my Xonar Essence ST (since it is supposed to be super low jitter) to the HDP's coax in My problem is that I'm noticing some small hissing with the lower volume levels, it disappears when I turn the volume up a little and when I...

  Quote:   The equipment you mentioned is on another league compared to the HDP, well, coming from an Essence ST I don't think I'd notice a small soundstage by comparison. 

  Quote: Interesting, so, I could get the HDP and then get one of those amps and use the HDP as a DAC only and get a noticeable improvement in sound quality?

  Quote:   Quote: To which amps have you compared the HDP to conclude that the soundstage is lacking? And which headphones did you use with them?

Thanks for the reply, HeadphoneAddict. I checked in another review that the HDP doesn't upsample anything, so you were right.     Now, would I notice an improvement in sound quality if I upgrade the HDP's PSU to this one?  ...

I'm getting very interested in the Icon HDP for pairing up with the HD 650s that I'm waiting to arrive, so my question is: Does the HDP upsample everything?   Also, thanks a lot for the excellent review.
