BTW., did you use TAKMEN resistors on this great 507pp ?? I found some resistor looks very familar, I like it so much.  
 
Hope to have an audition to it soon.

Vash兄,  
 
807PP今日剛開聲, 初步感覺良好, 實測數據跟電腦預計差不多, 只需要值少許微調及煲練, 相信很快就可以外訪到你處啦!

I have roughly run through the DGG site. The stock looks pretty limited. What's worse, good recordings are few and far between, no more than 10 in fact worth venturing into.  
 
Prices are not encouraging either. At around HK $100 per CD download, it is more expensive than buying the actual CD, and without packaging too.  
 
Since the cost of running the web-site is more or less fixed and the recordings are already there without incurring additional costs, I cannot but wonder for what purpose this download option has been intended.  
 
Sounds utterly ridiculous!

BTW, do I need things like foobar or similar programs to play flac files? If so, what are the simplest options then?

the simplest option would be to convert the flac back to wav and burn them into CD and listen to it using your existing setup.

Dear Limage,  
 
Both foobar and cplay are simple and easy to use open free ware for flac playback. If you aim for graphical interface, there are still plenty of choice say mediamonkey, jmc, etc.  
 
For primary trial with DGG flac issues, since it is factory produced 16/44.1, I think it must be a better choice than home ripping from CD. Then you can link it up with Gingers' good sound AudioNote DAC.

Thanks Vash. I am browsing through their site.  
 
As far as recording quality is concerned, however, DGG is a curious mixture of blessing and curse. They are fully capable of producing the very best recording on earth, but then the same recording team can be utterly disappointing in the next instance. There ought to be some chronic illness somewhere along their production line.  
 
Unless the recording is of known quality, I'll be hesitant to buy DGGs without a little reservation, although in terms of performance on the classical repertoire, they are virtually second to none.

DGG did already started the story. The FLAC lossless format may suitable for us. And they will be in my next shopping cart.

No, they are just ordinary CDs, although they claim the mastering process is most elaborate.  
 
I can assure you, however, that all 3 samples do not seem to benefit from the alleged efforts. I bought 3 in order to rule out singularity.  
 
It may have to do with the original recording, which is at best mediocre.  
 
If major brands like Decca, RCA, EMI and Philips et al are opening up their masters for download, it could be a very different story.

Just curious, can you play them all in ordinary CD player or do you need some special upsampling DAC to get the best result?

f the best recording should score 100, these three boxes could barely hit 50.  
---------  
well, in that case, you owe me say $400 for my cd transfer from tape to cd. for old time sake, i give you 20% discount. so you still owe me $320.

Thanks for reporting back. Being a vinyl man, I am totally lost with DSD, HDCD, SACD, XRCD, now HDTT - I guess this was the same when vinyl was trying to market their own formats with dynagroove, dynaflex, 78, FFRR, Long PLay, Stereo FFSS ...I guess the list goes on.

The 3 HQCD arrived. They cost me nearly 1,200 dollars including freight. I buy these as trials to find out just how good the HDTT has claimed they are. If they are real good, it will be interesting then to compare with the downloads that Vash has made using high resolution hardware.  
 
It did not take me anymore than 15 minutes to screen through these recordings, which were way below my expectation. If the best recording should score 100, these three boxes could barely hit 50. They all bear the same characteristics — lean, bright, compressed and fairly 2-dimensional, lacking in ambience as well as dynamics.  
 
So at the moment folks, my advice is to stay away from this HDTT label until they really produce something doing justice to their price tag.

Neither do I.  
 
Ben,  
 
If you want to phase align different drivers, pulses are not going to help much except to drive you further into confusion.  
 
The best way IMHO, and the most practical way yet, is to use a piece of good recording you are familiar with, and play it repeatedly while someone is there to move the individual drivers. The setting that gives you the best homogeneous sound field is the one to start working with.  
 
Subsequent fine-tuning may take months, or even years, when you get more and more incisive into the finest particles of this audio anatomy.  
 
It is fairly common to find freaks of this genre reporting audible improvements on daily basis throughout the year — endless fun guaranteed!

Er... Problem - My only other help is Adrian. Being 5 yr old, should I ask him to listen or move the speakers? On second thought... hmm.. he would love to do it and his hearing should be better.... My other boss... I dare not even ask..... Being a lowlife at home, I hope to get the most self-help I can. :-)  
 
Enough kidding around. Seriously, I am now using digital crossover which enables me to delay the signal at will. I find using a pop music with strong bass beat can help do the job. Yet, being skeptical of my hearing and the cd content, I hope to have a signal that is certain. Seeing from this light, nothing is more boring and uninvolving than test pulses.

i must say i don't have very good ears. i never find pink noise useful^-^

Na, you always know these stuffs much better than I do.  
 
What I am thinking of is something like 0.1s pink noise 0.1s silience, 0.1s pink noise 0.1s silience..... like a drum beat rythm.

Pink noise covers 20 to 20k. If we can make it into pulse form, then the clearer/more crispy the pulses are, the more coherent are drivers aligned timewise (both start and stop).

And I don't think it is necessary since we can use a tuner with "無電台訊號下" the sound "sa sa sa" is also a kind of the said noise.  
------  
i don't hink pink noise is just sa sa sa. it's spectrum is, i think, 1/f. but for burn in, i think it is better to use log sweep. this will ensure your system will go thru 20-20khz repeatedly.
