I regularly visit 6moons News Section that lately became quite good sources for audio news. It is same that Srajan not willing to share the news in RSS or compatible format, anyhow…
The today new is Elina Lamm announces that "we are extremely please...

[quote user="haralanov"]And the very same is with electromagnets. With those so widely used 12V power supplies (Fertin, Feastrex for instance) the sound is always softer than it should be in reality with severally restricted dynamics and transien...

Well to pile up superfluous things into audio components in order to make products more expensive is not alien thing in audio. My question was not about to mock the Raven company. It might be fine TT, I do not know anything about them and I do not p...

Dear Romy,The tracks are correctly listed.Yes, the tracks are varied and some are not good recordings at all. BUT if you want to listen to Billy Bean play guitar or you want to hear Louis Stewart's first recording as an 18 year old then you hav...

Ethan,
Since I published the article “Preamplifiers: keys to mystery” I received many emails from my site visitors asking about Lamm prams and questioning my remarks in comparing what I said to “data form other sources”. Some people disagreed or sur...

John, what you say
about power factor correction is completely accurate and very much makes sense.
There is a many ways to do it BTW. You can do it with caps compensating the
inductive load, you can do it with filtration or you can add active SS c...

Ok, I do not know what it was: was it DHT, was it 300B, was it some other specifics of this given amp or whatever… but those two aspects that I named: intentional density of colors and randomness of pace are something that I would like to exercise in...

Somebody from AA was asking about electromagnet. The subject pup up here from time to time but this time Bruce Edgar uploaded an interesting comment. Bruce is not a typical AA Moron and if he says “inaccurate things” then it is not due to ignoran...

even though they connected in “protective mode”. You can go with stabilized impedance
to maintain the high pass filter over the coupling capacitor to work prop...

[quote user="steverino"]Well I meant that in cases where the AC power wasn't simply larded with grunge but was irregular with outages you didn't need to be an audiophile to appreciate the product. Of course audiophiles find all kinds of things essent...

thread at post #89 you mention trouble you

Those both look fine, but all your voltages are hot...all of them. From afar it seems as though the primaries are not correct for the mains supply by about 15% eg. wound for 200V primary but you have 230V, or something like that. Where I am has nom...

Power from the company grid is usually pretty decent in most respects, or at least it used to be. In the last 25 years or so the average home has seen an increasing number of devices which have switching power supplies (computers, monitors, etc...

Roman,> Any IC-base RIAA corrector should cost $30, with no expiations.Now now.... My "Analogue Addicts Phono Stage" is Op-Amp based and requires at current OEM bugetary pricing in 1000pc lots of $12.25 each. Add Tinfoil & Polystyrene Capacito...

Finally done! A journey that took a total of 11 years after coming across this forum and seeing the Melquiades posts and schematic. Koshka has a beautiful body and will live on in my SET implementation of a 4 box solution. Here is the left channel po...

[quote user="guy sergeant"]I'm not really concerned whether passive eq no feedback pre-amps have recently become fashionable. I've been using them for 15-20 years. They've always sounded more natural to me. Most commercial implementations that I...

Hi Paul,My question was of cause about my phonostage based on EAR834p and "End Of Live" modification with air capacitors and LCLC + 0A2 power supply.A couple weeks before I increase the second stage ECC83 cathode capacitor value to 43400uF (Kaisei no...

Hi N-set,Yes I added big cap bank to the second stage cathode. Yes it is possible to use filament power supply for fixed bias like Romy did.But I have a stereo EAR834p with a single filament PS. So, I was afraid that one PS for both channels can caus...
