I grabbed it - have been looking for a US4 recently, and the only one available before Jeff's is a pro version which is out of my budget. It'll be used to drive HD800S, ADX5000 and L5000. I'm pretty confident on the first two; will see how it works with the last one.

Agree. Even without lockdown, it's not easy to audition susvara on either amp. A used Niimbus will make the risk lower, but I never found one. I'll be willing to trade my V550 pro for a US4, but I doubt anyone will down-grade like this.

Not yet. I connected my HD800S to the XLR extension cable of K1000 and tried to drive it with F1J, and heard only noises. It looks pin definitions of K1000 and HD800S are different.

My V550 pro's volume knob has noise as well, keeps giving soft clicking sound when I turn it. The noise happens near the knob but does not affect the audio signal. Without playing any music, I turn it to the maximum volume, and don't hear anything from the headphone.

Received my V550 pro 3 days ago; connected to bricasti M3 (ethernet input) and had some short listenings: - HD800S with stock single ended cable - works fine but too loud; for classical music, I need to set pre-gain to -18 to be able to turn volume to 12 o'clock. (M3 level is 0db) - K1000...

It's easier to compare retail prices due to different promotions going on. I remember drop V550 (standard) page has list price as $2799 and discounted price as $2499; the list price matches pre-orders above. Based on prices on both sides, DAC value is 3500 - 2800 = $700 using retail prices...

Thanks for the suggestion! Pre-ordered V550.

I almost pulled the trigger on V590 standard version this morning, then I saw this. Should I give up the relay volume and add $350 to get the built-in DAC is a real headache to me now. I assume the DAC is a step up from my Berkeley alpha 1st gen, which was expensive but is a product w/ 10+...

Looks a good match. Thank you! Class A speaker amp is really not that friendly for daily usage, like playing background music for WFH.

I googled niimbus + k1000 and your description is the only one found in head-fi and some other sites. Do you mind provide some more details - is the sound balanced and non-fatiguing, if possible, how does it compare against speaker amps, etc? I've been using FirstWatt F1j, and am considering...

I'm wondering if anyone tried K1000 on it. It's listed as 4.3W 20.7V on 100Ohms load, which looks promising. My current setup is 1st gen Berkeley Alpha -> first watt F1J -> K1000, and HD800s was added recently. If V590 handles both headphones well, I'll be really interested in switching to this...

Hi Keevs, I just tried 44.1/96/192Khz files, and the LED did not change color.

I got one last week: after installing driver it works flawlessly with my BADA-1 through both kernel streaming and asio.   Unfortunately this is my first usb adapter, so I cannot compare it to any similar product. My original target is Bel Canto ulink, but found this unit with the same name...

Can get a tascam cd-450 at about $550, anyone has experience with this player? Is it worth the price in comparison with other hifi players at similar price, Marantz 17mk3 for example? Really need some advice. Thank you very much!

Thanks lini. I am afraid Terratec Aureon has similiar power as my Revolution:-( To drive the 600Ohm 88dB 240DF to 100dB, I need a sound card which has 3 Vrms output. (My Revo is 1.26Vrms) I know that there are cards with such a huge output, but they are qutie low-level ones...

Sorry for post it here, since nobody answers in the source forum:-( At first I decided to buy a DT831 for my soundcard, which is a m-audio revolution (may upgrade later). However, considering the physical and sound comfortness, I finally changed for a K240DF after some audition, since DT831...

At first I decided to buy a DT831 for my soundcard, which is a m-audio revolution (may upgrade later). However, considering the physical and sound comfortness, I finally changed for a K240DF after some audition, since DT831 is too excited a headphone for a whole day's wear during work...

It just falled from the 1m computer desk, and the right side was completely mute now. Anyone has experience on decompose this can? Thanks!

To Rameish: yes, it is exactly Hung Brothers I have visited:-) I failed finding any good beyers and senns in Adelphi, the other place I knew. I think the boss got impatient after I had tried 831 and 880 for half an hour, so I left. Anyway, I can't buy a headphone based on the performance on a...

Thanks for all the advice! I have visited a shop yesterday and tried DT831 and DT880 directly in the headphone jack of a dvd player. 831 is tooooo shrill to me, and 880 is much better with moderate sound leakage. I don't know how things may change on a cd-p. DT770pro is closed, but not for...

Sorry for the Etys. I just don't like something sticking into my ears:-) I have searched the forum, found that "DT880 is rather open, although it is semi-open design". Anyone has experience with this?

Thanks FCJ. I won't consider earplugs, since they may be harmful to my ears, and I prefer to real headphones. I have a DT331 on my computer, the sound is just fine. DT831 is in my list, and also DT880. Could someone give a description on DT880's sound leak? I don't want to disturb my roommate:-)

My room is just near an express way, and there are trucks roaring even at 1 am (although I'm on storey 10:-) Currently I am using an AKG K-501 bought three months ago. I like it pretty much, except for a little lack of bass for symphony. But it's completely open... I think I should change...

sorry, I have obtained wrong data :-)

I am in Singapore now. Price may be a little different from in US, and many articles in eBay are not available here. It seems the Marantz CDP is too expensive for my budget, since many of you replace it with a cheaper one and an amp. Yesterday I have decided to buy an amp in future :-) It's a...
