Does anyone have a picture of the power cable that came with the Codex? I've mixed my power cords and can't figure out which one is the one that came with it. Thanks

For what is worth as an owner of this iDAC2 here is my feedback. Technology is moving relatively fast and this is no exception when it comes to DAC's. 20 years ago when I was a teenager, I went to my local high-end audio store and the store manager had given me an advice on DAC's that have struct me and stuck in my head ever since. "Buy a DAC that you feel comfortable spending money on which brings musical satisfaction to your ears". Today we have a plethora of good selections out there that bring musical satisfaction to our ears without spending thousands of dollars. As I am a father of two, spending money carefully is highly important. DAC's are the type of units that typically loose their value as technology is progressing in comparison to speakers, turntables, amps etc. 20 years ago there was no such thing as 96k files never mind anything higher than that. As I continue to enjoy LP's due to widely known benefits, I've been keen on DAC's that are musical and most importantly provide enjoyment in to listening to music. Prior to purchasing an iDAC2, I had an ASUS STX sound card and quickly switched to a Centrance Dacport LX as it was all around superior to the ASUS STX sound card. I've been enjoying this DAC for roughly 3 years however as technology is moving now to DSD, I wanted to get a DAC that would cover all future sampling rates but most importantly being musical. The iDAC2 fits the bill nicely and overall sound improvement to the Dacport LX is large enough to justify this purchase and then some more. It is a very musical DAC for the money with a really good sense of details and space. Couldn't ask for anything more! Happy listening!

Thank you very much for your reply. I've heard a lot of people recommending the Lynx AES16. Any other cards that are as good however more suited for DAC's with RCA SPDIF inputs?

Hello, I have a PS Audio Digital Link III driven by a Xonar ST/STX, wondering if any gains would be had if I switch to a USB to SPDIF such as Halide Bridge or Audiophilleo 2. Any feedback would be much appreciated! Thank you in advance.

Thank you. My system has changed a bit since my review. I've changed from cheap RCA interconnects to Audioquest King Cobras, I have experimented with op-amps on my sound card and finally switched to OPA627's because AD8620's without a surprise they sounded too aggressive, in your face type of sound that really didn't suit my style. With all the changes the sound signature has changed with favorable results. Overall balance of sound with the Grado's from bottom low to upper highs have brought some great definition and most importantly very balanced. Thanks for all the input.

Over a decade ago I wanted to get a system setup in my listening room to enjoy music. I’ve been lucky to work for a respected audio distributor that allowed me to interact with some excellent engineers and solid product range. The system that I had setup provided me with a lot of satisfaction but since 5 years ago I moved and unfortunately found that the listening area wasn’t ideal. I found it painful to try and setup the system to its optimal position and unfortunately I wasn’t successful without the speakers getting in the way. The enjoyment of just listening to music was affected because of the less then standard speaker placement and ended up critiquing the sound rather than simply enjoy the music. Sharing the space with my wife complicated things Life for the last few years got really busy and had no time to sit and enjoy music and I started to miss that. One day I started listening to my music from my 10 year old Grado SR-60’s hooked up to my Iphone and I realized what I’ve been missing. There is no doubt that the Grado SR-60’s are one if not the best headphones for the price. These headphones had a lot of use especially at the gym regardless how dorky I might have looked. It was time to get a new pair for serious listening at home. I wanted a pair of headphones to be efficient enough to be driven even by an Iphone. Although most if not all Grado headphones are rated at 32 Ohms, they are very efficient. I wanted to get a pair that had excellent soundstage, clarity but most importantly a joy to listen to for many years to come… Lo and behold! The PS-1000 Grado headphones! Before anyone listens to these headphones seriously, they need to be broken-in for at least 100 hours. John Grado states that they need to be broken-in with normal use and not with continuous 24/h a day signal. This forced me to become more patient but made it an enjoyable one nevertheless. The difference was noticeable as the drivers started to loosen up. Bass became more defined and the sound started to really open up. As I am no real expert I will do my best to describe the sound. I’ve listened to Sennheiser’s for a short time but my comparison is to SR-60’s as I’m only very familiar with them and I’m in no position to compare to other headphones. This post is more for anyone who is interested with my experience was and perhaps help anyone make a decision. Clarity Probably one of the strongest points for these headphones. The level of clarity compared to SR-60’s as expected is huge. My music selection is very diverse, from electronic based such as Delerium, Massive Attack to Pink Floyd, etc. With the PS1000’s I naturally fell in love with acoustic based music. The amount of detail from each instrument transported me into the musicians’ room. Soundstage/depth The soundstage from these headphones is impressive. Music extended all around me. I am sure that other manufacturers in this price range have also nailed it. It’s impressive that this level of soundstage was only accomplished by speakers years back. Compared to the SR-60’s music is no longer in your head but all around you. Bass I’m having a little difficulty to rate the bass coming from these headphones. The bass no doubt goes deep and is well controlled. However at times I do feel that the bass is a little on the lean side when listening to some songs. If anyone is looking for headphones that will make your brain shake from the level of bass, these headphones may not be your choice. Source (iPhone) As mentioned earlier, listening through an iPhone, the tonal balance is surprisingly natural. However as expected listening straight from the headphone jack does not bring the last detail from the music. Instruments bland a little but nevertheless that didn’t stop me from enjoying the music. Compared to the SR-60’s the sound difference is still big with an iPhone. Sound level from both headphones when used with an iPhone is sufficient! Source: Centrance DACport I bought the DACport when I am travelling or when I want to take my laptop with me to bed and listen to some music before going to sleep. The sound is smooth, detailed and plays loud. Preferred volume setting is a little over half way. It’s an impressive little DAC/headphone amp especially when you are on the go. Source (Asus Xonar ST, Headphone Out) + AD8620BR + LME49720 Op-Amps My main source is from the PC via Asus Xonar ST soundcard that was favourably reviewed by Stereophile as a good step forward to high-end audio. I had replaced the op-amps with positive results when listening from my SR-60’s. The AD8620BR op-amps are known for excellent detail and soundstage with a more forward high frequency sound which mated well with the SR-60’s. However when listening to the PS-1000’s with these op-amps, made the sound somewhat harsh with a few recordings and I preferred the sound from the Centrance DACport instead. Source (Asus Xonar ST, Line Out with Mapletree Audio Design EAR+HD headphone amp) EAR+HD Mapletree Headphone amp Purchasing this amp was one of the best purchases I’ve made for a long time and made me fall in love with tube sound. As mentioned listening straight from the headphone out from the Asus Xonar ST soundcard with the PS1000 sounded a little too forward for my liking. Dr. Lloyd Peppard has truly designed an excellent headphone amp that makes a match made in heaven with my Grado’s. The sound is detailed but very smooth and natural. This is when my vocabulary comes short. Soundstage is deeper then what I’ve heard before with no harshness found from previous setup. The sound comes alive with better impact. I’m planning to do anything possible to keep this amp going for 20+ years I’m that impressed with the sound quality from this amp. Overall impressions (Grado PS-1000 + Mapletree Audio EAR+HD) Grado PS-1000 headphones with the Mapletree Audio EAR+ HD headphone amp helped me fall in love with music again. I was surprised to see the difference in sound from all the sources I previously mentioned. Some very favourable and some not so much. It just shows how important it is to have a properly matched source with these headphones. This setup is the best I’ve heard and matches if not surpasses a high-end rig that cots 10x the cost of this setup without worrying about speaker placement and room acoustics. I am once again able to enjoy music and get excited with new material! What’s in the future? Perhaps get a dedicated DAC connected to my computer. The DAC that has grabbed my attention is the Ayre QB-9 but I’m more than happy with the current setup to enjoy my music and allow me to save. Hope this post was useful to some of you searching for one of the best headphones and headphone amp Happy listening! -Tom-
