    Hifiman HE1000 Planar Dynamic Headphone

    Coming from Stax world ( X9K) to planars and Hifiman new HE1K stealth. Have avoided to listen to planars because they don't present the liquidity like a excellent electrostatic headphone. First i had on loan a topping D90 amp to test how it matches with the new stealth , big disappoitment...

    Stax SR-X9000

    EnVogue DaCapo left, made in Italy, sold in Germany on name EnVogue some 25 years ago but these are rebuild in Netherlands to the lastest specifications, probably don't find it anywhere, very rare price back then some 12K. Right Energon electrostatic amp, custom made in Hungary, is probably...

    Stax SR-X9000

    Try to research how far you can get X9K. Feed the Energon amp straight with tube preamp and result is some sort of of out of body experience , the music appears to come from nowhere, at least you have the feeling that certainly not from the phones. The X9K is smooth like butter and musical as...

    Stax SR-X9000

    that's exactly right ,colored amps is asked when driving X9K to it's best, to make critical listening with Novem the amp must be warmed up at least 20 minutes. I use Judy Spotheim passive preamp infront of Novem, have turned volume on max and adjust it through it. I can make straight comparisons...

    Stax SR-X9000

    A feature wich not often comes to mind if listening only with one amp. The Novem amp fit's the X9K in that sense that it presents a "right size" to X9K. My other tube amp, double mono design, presents a huge soundstage much more than Novem but the problem comes here. If you listen from Tidal...

    The Stax Thread III

    I wasn't sure about Novem first but realized later that it needs "burn in " in time at least 2-3 months as many other tube amps do. The tubes are critical, i would avoid the JJ ecc99 gold pin output tube and use the normal silver pin instead. Input tubes are also critical, NOS Mullard has been...

    The Stax Thread III

    Always coming back to Novem amp/Mjölnir Audio with NOS Mullard input tubes , sounds really nice with X9K, looks good after i switched a silver colored potentiometer to it. Warm tube sound but still presents all details

    Stax SR-X9000

    My personal experience is that it is easier with dynamic amps to make a combo sound good, electrostatic amps are almost individual matches, you buy an amp particularly for X9K or 009. It's rare that you have a good match with two different phone models. When you buy for instance X9K you have to...
