Yeh but that's my point... I don't use the D10 as a portable device, so I might as well get a desktop setup that'll have better sq for the money. I like the D10 too but the highs are a little too sharp for me. And it doesn't provide enough power if I want to upgrade to HD650

I've ordered a Sparrow. Given that SQ is similar to the Fun, it can't be far from that of the HDP, and it's almost three times cheaper !   I'll be able to sell my D10 for the same price or even more. 

Here's what audio gd wrote by email. Sparrow sound is same grade with the FUN but less the option. The Sparrow version A-BNC price is USD210. The DA chips had upgrade to WM8741

But I believe I've read several times the sparrow is equivalent to the fun, minus controls (for bass and highs).

How do you think the sparrow compares to the HDP?

Quote: OK, so you're essentially saying the Compass (and the FUN) are better than the HDP as standalone units?  I'm not sure about combining an Audio GD and a DAC. It'll cost a lot, I'm not sure it'll be that different to standalone units...   If I buy a dedicated amp I'd probably go...

OK, thank you all.    Maybe I should just order the HDP then, but I'm a little concerned it won't be a great improvement compared to the hd 595 and D10. It's hard to know without trying...   Any one else has an opinion on the HDP's AMP?

Hi everyone.   I am currently enjoying my HD595 with an Ibasso D10, which I enhanced with HiFlight's old Topkit (TLE2141/EL8201). This setup produces nice detailed sounds. However, after trying the HD850 on a Marantz, I feel a need for something a little more sophisticated, and with more...

Apparently the OPA2350/EL8201 combo is also quiet good for Senns ? But I can't find an EL8201 for sale anywhere. Where can you buy your opamps online, apart from ebay? Every site I visit only offers massive orders. And I'm serious about buying a OPA2211 with the right socket, if anyone...

OK. Guess I should switch to the 2211 then. You're not selling a socketed 2211, by any chance? But thanks for the info. That was most eye opening.

Right I'm a newbie, so I still have a lot to learn in the field. I'm actually thinking of selling my d10 and hd595 for a bigger amp and a pair of HD650. At first, I thought my earring and knowledge would not allow me to make any difference. But now that I see how the sound can improve...

Yeah, you said it sounded particularly well with the D10 and I couldn't agree more. Except for the slight hissing. Maybe I'll ask for a replacement, see how it goes. But before doing that, I'd like to make sure I won't have the same thing with a new one. And I wonder if maybe the noise is...

OK, thanks for your expertise. It's a little dissapointing, seeing as many people consider the OPA2111 to be the best opamp for the D10. I guess you have to make some sacrifice, ie SQ vs background noise. However, I wonder if the noise level is not lower since I fully charged the battery...

Sorry, I'm really not good in electronics. I simply feed my D10 through USB, let the battery discharge and then charge it up again. I use the low gain switch. The hissing gets louder when I use the gain switch. Appart from that, it's just a regular, unmodified D10.
