I know it might be odd that the ratings of this review is a perfect score but for the price point of $50/1m you really can't go wrong with the DH Labs White Lightning RCA Interconnect.  Yes a well made cable will do better than the cable you can get at Radio Shack and Wal-Mart, but what scare many audiophiles away from cables is the usual high price and the motion of "snake-oil."  These are the interconnects I use for my DAC (Musiland Monitor 02 US) and my Turntable to phono (VPI Scout).  If you are looking for quality RCA interconnects without the snake-oil price then look no further than the White Lightning RCA Interconnect.  These cables doesn't act like $50 cables!

If you are looking for for a cheap Async DAC that does a lot for $150 then look no further than the Musiland Monitor 02 US. 
 
Unlike many DACs in the market this DAC focus on Computer Audio only (which is great for me since I don't need Toslink or Coax inputs).   Using Async USB the DAC delivers Hi-Fi sound performance, but I do have to question why Musiland have to use a lower-end Op-amp in the analog stage?  I'm thinking because of the lower-end Op-amp the DAC is not delivering up to 100% in my opinion. 
 
Because of Async this DAC for the price supports 24/192 files, but honestly most of my digital music is the redbook standard so the hi-rez doesn't get used often.  I listen to 24/176.4 files on this before (Reference Recordings HRx stuff) and I found the DAC to do a great job with those. 
 
If you decide that you want to use the Monitor 02 US as a digital transport you can.  With the Monitor 02 US using its own power source it will do a better job as a digital transport than the Monitor 01 US (which uses USB power which IMO should be avoided at all cost when it comes to audio).  It has Toslink and Coax outputs if you were wondering.  I prefer one-box DACs so I don't want to use the Monitor 02 US as a digital transport (but you can if you want). 
 
I think the issue people could see with this DAC that it is Windows only because of its drivers.  Also the drivers did cause issues on peoples computers (I heard that it was giving problems with Windows 7 computers with AMD processors, I had this problem before). 
 
Also by looking at the picture of the product it does have two headphone jacks.  Headphone jack 1 is for high impedance cans while 2 is for low impedance.  With my experience with the headphone jacks I would recommend to avoid them at all cost.  These headphone amps just don't cut it IMO with my Grados for example.  If you are getting this DAC you better get an external amp for your cans.
 
Overall with some issues this is a good value DAC for people who want to get into Hi-Fi without breaking the bank. 
 
Note:  I would say the drivers are adding in new features and now this DAC can decode HDCD (via driver software) and have a special precision mode so the internal clocks will be close to its perspective sampling rates.

If you want an introduction to the Grado sound look no further to the SR225i.  The special Grado sound is liked by many but also hated by many as well.  The best way for me to explain the Grado sound that it has characteristics of Warm sound with a nice touch of Brightness.  It is bright but not to the point of hurting your ears.  Because of this you will not find any of the Grado headphones to be netural sounding at all (colored sound).  I like my stuff colored (I like tubes as well, eh) so this is not an issue, but I will say it because that's the fact about any Grado.
 
The design for the most part is good but it is mostly plastic (some of the lettering is coming off) and it does take a very long time for the headphones to get comfortable.  I think the only major con of these headphones is comfort.  After a little awhile the headphones fit on my head just fine but it just took too long for that to happen.
 
Some people also say that the lower end Grados doesn't have enough bass.  For me the SR225i does a great job with bass (and great bass impact I must add).
 
Overall for $200 you really can't go around with the Grados.  The midrange really shines on these headphones. 
 
Note as of 06/09/10:  I should had add this in the review but an amp makes a big difference with the Grado headphones (or any headphone period).  Invest in a good one because a good amp will add in the suppose "missing bass" to the Grados.
