Before I order this amp, I have little questions to be clarified.   My current setup:   MHDT Havana DAC --> WooAudio GES --(LoopOut)--> Wooaudio 2   Wooaudio2 does not have any LoopOut. So if I get Concerto hook up to Havana DAC, what are my options?   My best guess is to get RCA...

hi guys,   I am currently running Desktop -> DAC -> Amp. The problem with my desktop is that its graphic card is noisy as hell. (ATI 4870x2) So I'm thinking of buying a new laptop just for the headphone system.  Apple looks nice but I have never used Mac before. I am looking for a quiet...

hello fellas   I have very little knowlege about electro currents.. so here I go. I have recently moved to Korea where the voltage is 220V. I was wondering if it is okay to use power cord that I bought from the States (Iron Lung Jellyfish) in here since the voltage in the States was...

After countless posts about how great K1000s are, it has come to my attention to consider one for myself. But then choosing a right amp is really hard for me because I really don't understand all that ohm, dbl, watt, and other scientific 'stuff' floating around with K1000. (if someone could...

okay guys, I have been enjoying HF-2 lately, but I am still desperately looking for "Wow blow me away" cans for Jazz. I have been playing around with Hd650, HF-2, AKG701, DT880 and they all sounds exciting. But, now it is time for me to wonder what the next step is. Should I go for HD800 or...

Good day everyone! I have been enjoying Havana for couple of months now. It is the first DAC I ever tried, and Im loving it. However, as time goes by, I am starting to wonder what the other DACs would sound like. Especially, Im interested in non-NOS DACs this time, using upsampling or whatever...

hi, everyone! A little advice please. I don't own any Grados but I cannot stop thinking of getting Grado cans. I have tried RS-1 and GS1000 from the dealers, and wasn't really impressed. But both times, they were hooked to some low-end amps and the listening environment was really noisy...

Hi, My tung-sol 5998 has green letters printed and partially silver coated on the side of tube. Is this silver coating on the side normal? From what I have seen from the web, the usual tong sol 5998 has white letters printed and no silver coating on the side of tube. However, I found one...

hi, From what I understand, the mutual conductance value of a tube will vary everytime you measure it (even with same tester). Is this true? How likely is it that all 4 tubes have tested values that are exactly same when tested for second time? I ask this because I recently bought 4...

hi, If you have no tube tester and would like to figure out the conductance values of tubes you already own, what are the options other than buying the tester. Is there any place providing tube testing service? Should I try local guitar shop? HELP~ Thanks

hi, Im trying to buy a tube for my DAC. I was trying to buy a JW-2C51 WE NOS from tubeworld.com and found these: 1 Kuhl-Tube cryo $100) JW-2C51 WE NOS (626=1956) D getter halo (36/26 and 38/26) recommended) 1 Kuhl-Tube cryo $95) JW-2C51 WE NOS (626=1956) D getter halo (36/26 and 42/26)...

a noobie question. From what I understand from this fourm, Toslink and Coaxial use some kind of digital signal, (oppose to analogue signal of RCA), that uses like 0s and 1s. If this is true, how do these connections transmit the level of volume? I use Toslink from PC to DAC, and was...

Okay, I am in a situation where I already spent $2k on DAC and amp, and need to buy power cord and rca cable. I was thinking of getting a cheap power cord just like the ones used for computers, and a cheap red&white RCA cable that you would get from buying typical electronics. (like ps2) Is...

Im currently wating for HD650 and Wooaudio 2 to be shipped & seeking for a dac to go with. (connecting to pc optical output) After searching this forum for couple of days now, I am still not sure what to go with. Will I see a great SQ difference in detail between Benchmark Dac1 and something...
