Pretty nice.
I went over to the Russian site and found they have a neat solid state amp too. I think it's Szekeres amp (or BJT counterpart) with screw-on transistor.
Do we have any Russian members? I am not living with a Russian ex-Judo-champ anymore. (Don't let me show his moves even on friendly banter.)

P.S. I am pretty darn sure there are wicked advanced DIY community in other non-English-speaking regions. (Oh yeah not everyone speaks English ... )
P.P.S. I am OK in Japanese, just so you know. JP DIYers tend to be older with a large number of retirees. Which means a good amount is not online. Much of it in paper published form.
Oh ... and I am young and everything to go with being youthful.

Excuse for my bad English language. No problems Valeri you're doing great. Yes please, that would be great. The specs and also the price would be interesting and if they want a UK distributor? I had a Russian in my back garden not too long ago, seemed a nice enough chap (long story) with a wooly hat and gloves.

Thanks
I today after work have come into shop and the amplifier has looked. The beautiful woman worked. Beautiful women usually do not study technics. I did not begin to ask it strongly. The amplifier has asked to show. The amplifier in a reality looks more beautifully than on a photo. It small, as four packs of cigarettes, and heavy as a brick. The woman has told, that the amplifier has two versions and two names. The first version refers to LACONIC HA-05T and has 220 volt of a feed. The second version has 110 volt of a feed and to refer to LUNCH BOX. The amplifier were only green and white color. The woman has told, that tomorrow will bring dark blue and red color. I shall buy tomorrow this amplifier. The price of this amplifier makes 2500 RUR (approximately 100 USD). This price will not cause crash of my budget. If you communication with this firm interests, I can help you.

Certainly, I'd like to buy one of the green ones to give it a go. If you can find out how much it would cost to ship it to the UK it would be appreciated.
Many thanks.
Mike.

absodamnlutely and even better are less prone to "me too" where everything is just a clone of everything else. If I had one wish some wacked out genie could lay on me it would be to have a full undertstanding of every single language known to humans. The bad news is I DO NOT have that skill but the GOOD NEWS is I have a right click "translate to english" capability and better yet,electronics is the universal language so even when I have no idea what the text says I can still tough out the schematic and evaluate it purewly on the merits BTW-I wish I could read German 'cause this site rocks www.jogis-roehrenbude.de/then there is this italian site that I can eventually figure out the projects but have a bit of a time navigating the site itself www.audiokit.it/ITAENG/LibriRiv/CHF/CHF3.htmI like it simply because it is different.Reminds me of my mail box Considering how many headphone amps are used with "computer as source" having a footprint that is deeper than it is wider makes sense unlike many amps that are so wide (because they NEED to make a "look at me" statement) they have no place on a desk.anything wider than 6-7 inches is a waste of space unless it can be used on its side. Vanity has crept into an area where sound should be paramount and why many end up spending $3K for an amp that is electronically or audibly no different than one selling for $250.i can give examples but instead will play nice and keep the peace ;D Oh yeah, welcome Valeri.A very nice first post.

I today have bought the lamp amplifier of dark blue color. Now I listen Rock-opera - Notre-Dame de Paris on headphones Beyer DT990. At me two disks. One piracy, the second license. Good impression: - there was a bass and the top range. - the sound became volumetric. Bad impression: - My sound card strongly rustles - the Piracy disk is made from MP3, a sound noticeably rough.
P.S. In shop I have noticed the transistor amplifier of beautiful red color. At it surprising color. It is similar to the silver, covered by a translucent layer of red copper. I could not behave in hands, and the amplifier of the transistor has bought. Houses my wife saw two amplifiers and red at once has hidden in the small female bag.. I did not notice in the wife never fanaticism to electronics. The unexpected result of this purchase - tomorrow my wife together with the girlfriend goes to female shop to search for a paint for the hair similar, I blossom the amplifier.

1-Simple fix-cheap 1:1 (10K:10K) line isolation transformer if the "rustles" is RFI or digital ground noise bleed through 2-More expensive fix-external USB DAC like the Fubar 3-The DIY option-Remove everything after the sound card CODEC and replace it with a Film and foil coupling capacitor of around 47uF You could try going directly to the personal web pages of your favorite performers/groups where many times they will have "free" downloads of selected cuts from concerts or even current albums otherwise see if you can borrow some CDs and report back Rickamundo

At me the integrated sound card. I think to replace it on external USB. I repeatedly listened to disks on DVD a receiver. It has less than noise, and the sound is better.

On the subject of USB Dacs, I've been following this site with interest: www.audiodiylab.com/If you look in the forum, under "Digital Stuffs", you'll see that they are in the process of developing a "Super DAC" which will include a USB input. It looks interesting and there is some positive feedback about the other DACs, so it might be what I'm looking for. There's a couple of block diagrams and and some images of the PCB layout. I couldn't comment on the merits of the design, but perhaps you could Rick.

I can't see the project without registering which to be honest bothers me on so many levels I can't bring myself to register so the following is more of a "general" comment on such "all out assualts" that I have come across over the years and may or may not relate directly.*************************************************** Every time I come across something meant to be the "answer" to all things I always see comprimise and/or a bloated overly complex circuit design which me being one of the original "TEAM KISS" members (maybe even the first rubs my rhubarb the wrong way. On the subject of a USB DAC you need to first identify exactly what the end use will be then go from there to choosing the actual chip. For example. The above fubar and Hagerman DACs use the PCM2702/PCM2704 chips with one having SPDIF output capability and the other analog only.That makes it a simple "USB to everything else" device and meant to interface existing gear to a computer bypassing the sound card entirely.For the intended use it is the best way to go since parts count is low and board layout simple (and in fact do-able on a perf board). Add to that the potential for portable use with a laptop which are pretty much universally dismal in the sound card area and you have the core of a good hard drive based portable/mobile music system. But say I want a "better" DAC section ? That would require stepping to the PCM2706/2707 chips which output an I2S buss stream thus avoiding all the SPDIF transmitter/receiver bloat from the system.This requires that the DAC chip be either I2S compatible or have an adapter interface between the USB chip and the DAC chip but a far better option if doing a "from scratch" build simply because you can nail down the part to part specifics to work with the selected parts to in the end have a superior sounding device (hopefully ). So option "A" is a universal use it with anything project while option "B" is more dedicated to being a totally integrated device that once built is locked in to being that one thing and that is where any persons idea of "ultimate" may not be anothers idea of even good ! what if you do not like the chosen DAC chips sonics ? and if the design is called "open ended" where the end user can determine which DAC chip they want to use then from the very outset you have a comprimised design meant to please many things while not being exactly suited to any........at least that is how i feel about such things ;D Further,having spdif AND I2s on the same card means the I2s will suffer interference so while you have folks claiming "universal" what you end up with is "well,it kinda works for both but not really great with either" which in my mind defeats the entire reason for tackling the project. I think simple is always best if there is a choice,personal opinion only folks,and rather than try to make one design be ALL things to ALL people it is better to optimise that simple design to be the best it can be. Looking at most of the so called "DIY USB DACS" I have to say most of the designers are so clueless as to almost be criminal because the end result of these group builds is always someone selling the pc boards in quatities enough to be considered real income while those who buy into all the exitement usually could have saved a shitload of hassle and grief by A-just spending the $200 on one of the above tested and proven options B-copying the evaluation board design provided by TI C-actually buying the eval board from TI Long winded way of saying the linked project MAY have merit but the Hagerman and fubar are proven designs that have no hidden 'gotchas" down the road requiring forum based troubleshooting to get working to satisfaction Analog Rick in a Digital World

Yes, it seems it is soon necessary so to make.
You managed to contact AUDIOKITS?

Probably there are problems with display of cyrillics to the screen of a computer. I on the computer do not see the alphabet of many languages.
I almost all the night long listened to different music c DVD a receiver. If a disk of CD-DA, from music it is possible to take pleasure. Oscar Benton and Russian group ÑHIJ composition PERECRESTOK (blues) very well sounds
