Thank you very much! I'll see if I can have a try on those amps! Concerning the sound card and output method, I decided no to use a sound card, which means I have to stick to optical output. I'll consider uber-Bifrost. Are there other dacs that you guys recommend?   btw, is it save not to...

Thank you for your advice! I may consider buying the HDVA 600 instead. I picked T1 just because it performs well in most situations. It is good overall, but does not excel in any particular cases. I would like to try other headphones that performs better than the T1. I guess I will not...

Decided to get a t1 with HDVD 800. t1 with P-1u is not a good match. Slightly too much at mid-range and it puts some of the vocals far backwards of the headphone, making it hard to listen to the vocals. The HDVD 800 makes the t1 an overall balanced headphone with great details. I tried HE-400...

Thanks for the advice, I guess I will not consider HE-400 and 500 for now.   How about HE-6 and the other Hifiman headphones?

Sorry for the late reply I will try the he-400 next week. Meanwhile, could you suggest headphones that sounds similar to HD650 but still can handle dance type of music?   It seems that HE-500 is also an option.   Thank you

  The problem is my friends warned me that the HD650 is not good at Japanese pop-music

I am currently using the HD598 with M1DAC & M1HPA. The sound is overall balanced and just a little bit warm, and I really love the sound this combo produces. However, I want to find a headphone that provides more detail and a little bit more bass, but still maintaining the overall balance. I am...

Just wondering if I would have the same or better sound if I use the D10 with the HA540? Quote:    

Thanks for your reply. So you are using iBasso D7 with Bellari HA540 amp? Can you describe how it sounds with the HD598 and the Q701?  Quote:  

OK, I'll consider this too. What if I want to input sound from PS3?   Quote:  

Someone did recommend these two dacs to me but I can't find a shop to have a try. Can you tell the difference between these two and the X-can V8p or M1 HPA?   Quote:  

Is there any other options? Since I am not going to use it outdoors so the size of the dac is not my concern.   Quote:  

How about the iBasso D10?

Thread updated.     I may buy a new headphone in the future. But for now, I need to improve the quality of source as DeathDomokun says. Quote: Quote:  

So I am going to buy a better dac. What are my options if my budget is US$700(dac+amp) ?   Quote:  

In this case, having a better dac or a better amp will make a larger difference in terms of details and fequency balanced?   Quote:  

How's the sound in details?   Quote:  

Can you guys specify their advantages and disadvantages? Because I found the soundstage and details are narrow and unclear with DACs under $350.   Quote:     Quote:  

My friend told me it would be useless if I am using the computer output directly and add an amp to the system. I need a dac before having an amp.   Quote:  

I have read some of the posts here about HD598 and I still cannot get the answer of how to choose a suitable dac/amp for HD598. Here's the situation.   I bought the HD598 a year ago and I have tried a lot of dac and dac combos for the HD598. Since this is the first time I bought a...
