Thank you Trechnobear; I have ordered this. Let's see if they can complete the order!

Micro iUSB3.0. Below is their email: Hi Peter, Further to my email yesterday, iFi have advised the iFi Audio Micro iUSB3.0 Power supply has now been discontinued and no longer available. The item has been removed from our website. Is there anything else you wish to consider? If not, do you...

I have just tried to purchase this new from Futureshop, who have been told that it is no longer for sale. Could iFi audio confirm this is the case, and if they intend to launch a replacement?

Just thought I would add my impressions of the HD800S. and HD800.   I am now using both headphones with the Lumin S1 directly feeding a Trilogy Audio 933 Headphone Amplifier. In my personal opinion, the HD800S is a very worthy upgrade to the HD800 as it offers a very detailed bass that I think...

Over the years I have tried many headphones in an attempt to better the HD800. Although I have not tried the HE1000 or LCD4, experience tells me they will not offer anything substantially better for the price to be paid.   It is far more important to match the amplifier. By far the best match...

I would strongly advise borrowing one for a comparison. the S1 has a superb three dimensional DAC, which is why I bought it to replace my T1.

I agree with all the positive comments regarding Lumin products.   After years of ploughing money into PC based FLAC delivery, I took the plunge and bought a Lumin T1. I just couldn't believe how good it sounded, with a superb DAC built in that outclasses the Eximus DP1 (and that is a damn...

So you know money isn't everything, one of the best DAC's I have heard with the dual CMA800R is the Teac UD-501 using XLR. Be patient though, it needs A LONG burn in period. at the other end of the scale, I also tried a Weiss 202 that sounded horrendous.

I couldn't agree more. I am currently using two CMA800R with the Teac UD-501 DAC connected with XLR cables. It really is a great sounding setup.

With regards to USB noise from a PC/laptop. I would strongly recommend using the iFi USB Audio Power Supply and Gemini cable. This makes a massive difference to the sound. I could not live without one. It works a treat with the Teac DAC.   Websites here: http://www.ifi-audio.com/en/iUSB.html...

New to this Teac forum, but I do agree this is a great DAC. I initially bought this as a temporary measure until the DAC I wanted was available. However, I may just keep it, as it is really growing on me. I do believe it needs a lot of burn in time, but just gets better. Prior to this I had the...

 

Yes, I agree. The Teac is a great sounding piece of kit. I am using it balanced XLR to a pair of Questyle CMA800R Headphone amplifiers. I think it needs a lot of running time to fully burn in, but is definitely worth the wait!

I too had exactly the same issue when I bought my first Questyle amp. Before sending it back, I offered to replace the internal fuses to try and save the hassle of replacing it, but they wanted it back with the fault present. After testing, they told me the issue WAS the fuses after all.   As...

I totally agree with your comments. I also used to have that Sony SACD, but sold it a very long time ago.   Initially, my plan was to buy the Questyle CAS192, and use a passive preamp to control my two CMA800R amps, but was told by Alden that they had stopped making it. Therefore, I was not...

According to Alden at Questyle, they are working on an updated version of their CAS192 DAC to include DSD. This should also make for an interesting partnership with the CMA800R. Up to now, I have tried the CMA800R with the Eximus, Naim DAC and the recent Teac DAC. Impressive listening with all...

The Nuforce looks an interesting design as well. The dual mono idea seems to be catching on.   When I got my first CMA800R, I tried it using fixed output from an Eximus and then a Naim DAC. I found the sound to be better using variable output, especially from the Naim, as this added slightly...

You have hit the nail on the head here. Fully balanced through the Eximus is not as good (for me) as dual mono through the Naim. There was also a massive improvement in sound stage moving from one CMA800R to two in dual mono. The bass especially is incredibly powerful but not overbearing...

Here is a picture of what I am using this with. I hope it won't be considered too smug showing this:     I have used the Questyle combination with an Eximus DP1 and Naim DAC (as in the above photo). The Naim is by far the better match for me. I also use HD800 headphones. What is immediately...

Following on from the great review by project86. I am now using two CMA800R in a balanced combination. The sound is nothing short of breathtaking, and worth every penny (or cent). IMO this combination is as good as it gets...

The CMA800 Reference sounds like a very promising amp indeed. I tried it last night with an Eximus DP1 and Naim V1 DAC. The clarity is superb.   At the moment, I much prefer it with the Naim, as it has given the strong bass and 'Naim' soundstage huge openness and clarity. This is exactly what...

I received the reference version of this amplifier yesterday. As you can see from the picture below, the daft spiked feet have been replaced by something more sensible:       Below are a couple of internal pictures that show changes made to the layout of the amplifier:       I...

Yes, Alden has confirmed to me that they can be used like monoblock headphone amplifiers. I wanted to clarify that I could use two of them with either my Eximus DP1 or Naim DCA V1. He has stated that is how they are meant to be used.   I would imagine then, that Questyle will now have to bring...

Good news! The replacement amp is on its way! The model number is CMA800R. Here is an image of it before it was packed for shipping:     Here are the notes sent to me by Alden:   1. This is the upgraded version, model name is change to CMA800R, "R" means "Reference". With the full balance...
