post #481 of 1664

I believe this is one of Ted's cables as well. This was the pair that was at the SoCal meet.

On something different: I have been comparing DSD and PCM versions of the same track on the AK240 and I haven't been noticing any significant differences between them. The PCM versions are already good enough that I don't think I'll waste the space on DSD tracks unless they are direct recordings. I think iriver has done a great job making even 44.1/16 music sound fantastic.

Hi Currawong,

 

Please keep in mind that many DSD titles come from the original SACD release which means there was conversion from DSD to PCM back to DSD for the mastering process. This translation of the original file has a deteriorative effect on the sound. Recordings that are created in pure DSD with no conversions can sound pretty spectacular, and if they are double rate, i.e., 5.6Mhz instead of 2.8Mhz, even better so.

 

oops, I see now you know this with your comment on direct recordings ... sorry for my hasty comment. :blink:

did a variant of 2.5mm TRRS to RSA.

still hoping for a gold RA 2.5mm TRRS to save on space.

No worries. Something worth considering: A direct recording to tape, which is then converted to DSD or PCM without intermediate steps can also sound spectacular, but I do appreciate that there are people out there trying to make better recordings. Speaking of which, that Fiona Bevan binaural recording that blew me, and other people away...;)

Absolutely, DSD recordings that come from the master tape can sound wonderful. I went ahead and downloaded the DSD Showcase sampler from Opus 3 in double DSD format, and it comes from a master tape.

 

I haven't played around with binaural recordings much, probably should ...

Do you guys think DSD will really catch on? Maybe see places like HD Tracks offering ?

I certainly hope so but I suspect the answer will be a yes and no.  I don't think DSD will replace other lossless formats.  A good DSD is made from masters which takes effort and that translates to additional expense i.e. an additional cost to the consumer. Therefore, they will likely always be more expensive than other lossless formats which routinely are 16bit x 44kHz to 24bit x 192kHz.  However, I do believe there is a market.  If someone is going to remaster they might as well create a DSD version along ALAC, FLAC, AAC etc. 

 

There has been debate here on whether the improvement around DSD can be perceived by the human ear etc.  I found on my AK240 that the DSD's sound "fuller".  It might be that this is due to the fact that I usually only listen to DSD's made from masters so they are likely well engineered and that DSD is just a byproduct. Who knows but I do like my DSD recordings albeit my small library of them.

Received my AK240 late last week.  Finally got around to listening - especially compared to my RWAK120.  I have to admit that I'm less than overwhelmed in the differences in the sound between the two.  I'm not saying the sound is bad - it's good, but not significantly better than the RWAK120.  Perhaps I unrealistically expected to be blown away by the AK240 in comparison to the RWAK120 but, simply from a sound quality point of view, single ended using my IE800's, they're very close in sound.  For the huge price differential I'm not sure it's worth keeping the AK240.  Decisions...

 

Also, I'm finding that the side control buttons aren't working for me.  I can pause a track but I'm unable to resume play or switch tracks if the screen is off.  Works fine with the screen on but that kind of defeats the purpose of the buttons.  Anyone else have this problem? I don't see a setting related to the the buttons - maybe I'm missing something.

As I promised to you , tonight I have time the comparison between Duet vs RS 71 B new version ( up April 2013 Ray Samuel increase the high gain similar to his Intruder )

Source : AK 240 use line out
Amp : Cypher Labs Duet
RSA RS 71 B
Iem : Earsonic Sm 64 v2 use stock cable
Cable : mini to mini Crystal Cable Dream line with Viablue mini plug DIY

RS 71 B
High : more extended than Duet , better clarity than Duet , but sound to thin
Mid : more to mid high and thin sounding mid
Bass : is not so tight , a bit blur , not so bass impact and slam
Separation : very good separation ,
Soundstage : slightly wider soundstage than Duet , but less depth , less fuller sound
Power : below Duet , we can feel Duet has better power
Background : on par , duet has slightly black background
Noise : no hiss , very low noise floor
Gain : low

Overall :
RS 71 B sound with very good clarity , but overall sound so thin with a bit blur bass

Duet
High : not so extended like RS 71 B , SQ more present and more natural
Mid : very sweet , thicker , better pronounce and sound more natural
Bass : Duet has better bass impact , detail. And full Budy bass impact and cleaner with better rendering
Separation : very good separation too
Soundstage : less wide than RS 71 B , with better depth
Power : Duet has more juice than RS 71 B
Background : black background , slightly better than RS 71 B
Noise : very low noise floor / no hiss
Gain : low

Overall :
I prefer Duet sound character pair with AK 240 , to my ears more natural with slightly less clarity , but it is not dull
Cymbal sound more natural and more presents.
Midrange more weight , guitar more body and better pronounce , RS 71 B Guitar sound a bit Thin
Bass : better bass body and bass impact
If you turn the volume Lauder , you hear Duet has fuller sound

I haven't tried to headphone , my opinion would be the same impression

IMO

Nicely done Rudi, I'm happy because I had my portables narrowed down to these 2, but leaning toward the duet. I'll be ordering mine tonight, along with all needed cables.

About the Duet, I have heard from a distributor "....Instead I would opt recent version of ALO RX-mk3-B+. The latter is further development from what's now called Duett. I also like the Bass-fine-control..... previous ALO RX Version did have HISS issue, but with B+ version almost all issues are solved. And remember, Duett is based on old RX-mk3 version!"

 

Just for your information. I have no way to control if this is true...

I have ALO Rx 3 B , I prefer ALO Rx 3 B than ALO Rx 3 B+
ALO Rx 3 B+ has better bass impact and full body Bass , the rest about the sound quality I prefer ALO Rx 3 B
ALO Rx 3 B has better clarity , music separation and better soundstage
I have Dont The comparison these Two Alo Rx 3 B and Alo Rx 3 B + , 5 month ago , because I will to trade in my ALO Rx 3 B for ALO Rx 3 B +

Because of less clarity I keep my ALO Rx 3 B until now
Hiss is about the same , Rx 3 B + is slightly better

Duet is dead silent

IMO

Here is my impression between Duet and Rx Mk3B. My test rig is ipod touch 5G connected to VentureCraft 12V DD Socket 1 limited edition with MUSES01 and Fitear MH335DW CIEM. I didn’t have a lot of time listen to them during new year but, so far, this is my impression on it.

The first thing that hit me when I plug my MH335DW to the Duet is how quiet it is. Comparing to Mk3B, Duet background noise is like “Wait!, did I already turn on the amp?”. If you owned or heard Mk3B on sensitive iem before, you will understand with I’m talking about. The background noise is almost unnoticeable.

Duet sound slightly brighter than Mk3B. Bass is definitely cleaner, tighter, less overwhelming and more controlled than Mk3B. The quality of bass improve a lot toward the upper ends. Both Duet and Mk3B’s mids are very clean and clear. I found that Duet’s mids are slightly forwarded and brighter than Mk3B. Trebles are almost identical between the two.

Soundstage width is very similar but Mk3B has slightly more depth to it. Mk3B seem to have slightly better 3D representation.

I have read a ton on both of these amps, and the SR-71b. The ALO seems very good , also the noise floor also seemed to get worse with different iem's, and being this is a portable rig, I also didn't want that second knob in the way. Sound wise, I think they are both very good units. I'll give the duet a shot, if I'm not happy, guess I'll be buying something else. Thanks for the input, I always love other opinions.
