 I am a firm supporter and advicate of DSD and record most of my recordings in it. But seeing claims that DSD contains  up to 256x more data than CD is not just sugar coating, it is downright misleading. I would have expected some more honesty from the likes of TEAC. This undermines the credibility of up to now highly regarded manufacturer in my eyes. DSD is 1 bit system, PCM is multibit - and even CD has 44.1 kHz times 16 bit data - not times 1bit; what it would have had...
It depends for which cartridge mass and compliance is the headshell meant. It usually boils down to hunt for the lighte/r/st headshell(s), as normally the S arms are quite massive all by themselves. And that means vintage and even back then, lighter versions of quality were relatively rare. Vintage, rare, etc translates today in $$$. You may also like the headshell to have azimuth adjustment - which additionally compounds the problem. If any of the vintage rigid but light...
Add a disco ball light motor off ebay  and DIY some mount for it, you get an almost perfect "grill" for your vinyl. As I am from EU, this is what I would go for :  http://www.ebay.de/itm/Spiegelkugelmotor-MD-1030-Drehmotor-fur-Discokugel-Spiegelkugel-Diskokugel-/281576624675?hash=item418f465223:g:k7MAAOSwzrxUxV62 Search for similar ( 3 RPM/minute ) motor(s) on ebay for places with 100 and 120 VAC mains - prices should be in the same range. Do you use pure distilled water...
In effect - yes. The usual action on the part of the amplifier manufacturers is to insert some resistance in series with the output - so that unplugging or plugging the TRS, which WILL and DOES mean short circuit for a moment, can not destroy the output circuitry. This can lead to deleterious effects with some headphones ( see Meier/Tyl link a few posts above ).Alternatively, some output short circuit protection is required - which again can mean adverse effect on sound,...
Both of what you mentioned is correct. The biggest issue with headphones I have is the *sigh* TRS jack(s).  Any headphone should have 4 terminals - each channel  separately, no possibility of short circuiting the output of the amp when plugging or unplugging the headphones in or out. No one would believe the sound something as lowly as Grado SR-60 can produce if driven right.  I have modified the output of the Perreaux SM2 preamp in order to be able to drive headphones -...
Your reasoning is correct. Better damping factor means better control. The most thorough treatment of headphone/impedance issues I have seen online is this : http://www.innerfidelity.com/content/musings-headphone-amplifier-output-impedance#lXxz1i8HoBHscGDw.97
Sorry guys, did not know that. For how long do(es) the SB version(s) hold their charge for the proper operation if there is no audio played for a while ? I've found the schematics for the SRD-6SB :  
No AC cable on this SRD 6SB ?
Nope - please read again. SRD-6 has AC power supply. SRD-6SB has no AC supply - and batteries inside. http://www.stax.co.jp/Pdf/OLD/SRD6SB.pdf It is true that RC constants of ES drivers are long - but not long enough to be capable of somehow bleeding the required polarizing voltage off the audio signal and hope for a full charge after a prolonged "next to silence" in say classical music. It is either electret (permanently polarized) or AC or DC ( Self Biasing in Stax'...
It was only Stax that produced SB transformers - even for speakers ( I wouldn't like to see the bill for battery replacement - some 3 thousand button cells per chanell ).This is if we are talking about true electrostatics, which require polarizing voltage to be supplied by the power supply. If it is electret, which means permanently charged, then you do not need any power supply. Schematics for the two can be completely equal ( if electret is also push-pull design ), the...
