The amps I mentioned in my previous post plus Cvalli LG I tried last week. Main improvement is the bass. Best I heard on a hp was Abyss , Dartzeel + HD800 is matching it now impact vise and much better on definition and extension. I tried signal test for low frequency , 18hz and onwards is...

Here is another experiment , Just connected my HD 800 to a Dartzeel power amp , straight to the speaker terminals. Audio Aero Prestige Signature is both the source and the pre. Best I have heard the HD 800... I am not saying go and buy a 10K + speaker amp for the HD 800 but if you have some...

I tried something interesting last week with the HD800. First to clarify , my main rig is Speaker based for some years (Boulder monos , Verdier platine for analog, Audio Aero Prestige Signature Edt. for pre and digital , B&W 800N for speakers and I only use Headphones for very late night...

Extending temple cushions helps the comfort a lot (mine are fully open) , the steel rods can also (the two red pieces) be taken out from the k1000 with a tiny hex allen key and can be bent (they are extremely stiff) to ease the pressure on the head. I opened them up 5-6mm each and the K1000 is...

Germania, I have a CD3000 and all the fake leather parts was in terrible condition , the headband was lost but the drivers and the cable was like new . I had a big piece of (about 50cm to 70 cm) amazingly soft and beautiful lambskin and also covered the headband and made a new strechy pad...

I noticed a problem with the srm1/mk2 , when there is no music playing I can hear a very very low noise hum on the 202s. It is impossible to notice it without trying to hear it when there is no music and impossible to notice when the music plays. The hum is a constant 40-50hz sound. I tried...

Yesterday I prepared a cable with a single pin with the shape of stax connector and inserted it in the 252A's pro bias socket than attached the cables other end to the bias cable in the srm1/mk2 (which I cut its connection from the amplifier) When there is no interconnect in the 252A the bias...

Yup! (4.7M right?)

I will get the new bias supply this week, will post how it sounds compared to 230V.

That was what my electrician predicted , he said that wont put out 580 only 500. He also suggested to have a custom wound transformer 220V primary 580V secondary and use some diodes on the way to convert AC to DC then limit the voltage with a zener string. Spritzer did you use a 5 Mega ohm...

Spritzer thanks for the lightning fast reply I am going in!

I found a 220v-220v 8VA isolation transformer locally(actually I am infront of the shop now) I hope, that wıll be ok to use a 8VA instead of 4VA. If I am not mistaken the 100k resistor in the circuit is a bleeder one, so it will limit over current and let only the necessary amount of current...

One more thing ' can you specify the the pro bias in detail (curren,voltage,polarity etc.') I visited the electrician that repaired my 252A and he suggests a different approach .So it would help me to have the exact proporties of the pro bias . As far as I know what I need is a constant ...

I completely understand the stand alone bias supply now , thanks alot again. Will post again when the circuit is built.
