  1. Quite a few interested parties sitting on the fence with this one, so I’ll just say don’t be shy as I am open to offers on this beautiful triode preamplifier.🙂 Regards, Steve.
  2. This amp is likely to sound superb. I had the same combination of tubes in a 38kg Mingda monobloc amp using 845-300B-6SN7 valves, sounded amazing. The Cayin is likely to be even better weighing in at 51kg! 👌 GLWTS
  3. No remote on this model.
  4. Doogie: you should see my current loudspeaker collection/affliction ...even more indulgent! Steve
  5. Haha Con! Like Rolex watches, one can never have too many Suprateks. The works of industrial art and good sound that they are. I'd like to keep this black beauty if only it had a phono stage like my other one in Jarrah ... Steve.
  6. Item: Supratek Cabernet 300B [DHT] Valve Preamplifier Location: Perth WA Price: $3200 Item Condition: Very Good Reason for selling: Surplus, I've got two of them ... Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: See below For sale is a lovely sounding Supratek Cabernet 300B DHT (Directly Heated Triode) linestage preamplifier. It is finished in the preferred piano gloss black over a solid copper chrome chassis, which in my opinion is the best looking in the Supratek range. The exotic circuit runs a myriad of nice tubes. There is a single Sovtek 5AR4 rectifier in the separate power supply and, in the main preamp chassis starting at the back, are two Sovtek 5881 regulators (placed close to the main preamp circuit for better sonics); a pair of EH 300B DHT output tubes; the two stage drivers incorporate a pair of 12BH4 tubes driving a pair of 6SN7 tubes. All very nice sounding valves that respond well to tube-rolling. It is especially worthwhile if you trial different 300B or 6SN7 varieties. Although I am told, changing the rectifier tube makes a difference too. If you know of Supratek, you will be aware that the designer and owner Mick Maloney has the ability to build and customize his circuits to be whatever you want. While his initial design goal always starts with good circuit design aiming for accuracy, he can also tailor the sound of his preamps to suit the customer's needs by using a different circuit, component changes and/or different valves. In view of this, the particular Supratek Cabernet preamp that I am offering sounds very detailed, clear and open ...with the combination of 300B + 6SN7 majoring on midrange beauty and sweetness in the treble. It is for example, the preferred sound of long time Stereonet member 'Thomo' who uses a 300B Supratek preamplifier. *Anyone in Perth is welcome to come and audition the Cabernet preamp in my home, I can also ship the item Australia wide using a courier at cost. Cheers, Steve.

    Going overboard in small room?

    To determine whether you have gone overboard with a large speaker in a small room, two things are negatively affected - imaging and bass. If you have not got enough room to spread the speakers or move them out from the front wall, then imaging will not have depth or have a narrow soundstage L to R, it will also not sound free and open. A big speaker placed against the front wall (because of a lack of room space) will most likely sound boomy and too bassy, it is over powering the room and there is nothing much you can do about it except to introduce EQ or tone control to cut the bass. If you like the sound of your Dyns in the room at the moment, then don’t worry about it all and just enjoy the music. Cheers, Steve.
  8. Yep, you ‘get’ what I am on about. Steve.
  9. Yes agree with that for the system you have shown, as my own room room and MarKT’s described above are large and has a spread across 6m x 8m, so probably works better.
  10. You know strangely enough that sort of speaker positioning can work out OK, depending on your room. In my own audio room if I fire the speakers out of the corner like that I get amazing imaging with excellent depth front to back and deeper bass, though I do prefer to point the speakers more directly at the listener rather than cross them in front of the listener. One of our experienced SNA members MarkT prefers to cross his expensive ATC-100 active monitors about one meter in front of the listening position. I have heard his system and it works, the speakers tend to disappear which is something we all want to achieve. I have also seen one reviewer in HiFi News UK magazine recommend crossing the speakers in front of the listener, so maybe don’t knock it until you hear the depicted system. Steve.
  11. I’m no expert on materials technology, but as I understand it the beryllium domes in the Yamaha NS1000 are very very hard (and stable), that is their reason for being. The high stiffness to weight ratio makes them the ideal pistonic speaker driver, making them one of the most accurate transducers on the planet. The vapour deposition technique involves the beryllium being reconstituted on a metal former, the former is then removed under high heat leaving an eggshell thin dome which is the speaker diaphragm. The process ensures that what you end up with is a stable piece of beryllium metal. It is long lasting and not really prone to flaking, but may produce a powdery oxide in as a by product of corrosion in humid/salt environments. This oxide could be toxic? but it would have to be ingested in some quantity to be lethal. The main risk with the Yamaha beryllium domes is when people fiddle with them and end up breaking the domes. Beryllium is highly toxic and if you ingested (ate) the broken pieces you would be poisoned by it. I guess the main risk is with toddlers and young children who tend to put anything in their mouths. The speakers metal grills are not 100% secure either, as the NS1000 is getting very old now and the glue or rubber holding the grills have dried out and shrunk making some of them loose fitting. At the end of the day, the NS1000 has been around since 1974 and there are more than 300,000 pairs out there in the world. As far as I am aware, while there has been reports of beryllium poisoning at the factory with Yamaha workers, there has not been one reported case of owners being adversely affected. Forty five years of usage across 300K+ users with no reported issues, is a pretty good track record. All just what I have seen in literature and across the web. Cheers, Steve.

    Technics SP-10 MkII spruce-up

    You guys are scaring me now with the need for cap replacements ...I treat my SP10 Mk II like an old car, if it ain’t broke don’t touch it. It just keeps going and going faultlessly over the years. I do have a back-up spare SP10 and psu in the attic. Maybe I should reappraise this approach and get the soldering iron out?? 🤔 Cheers, Steve.

    Quad II amps and 22 preamp fair price

    Plus, the Quad II + 22 combo doesn’t sound very good. Sounds mushy and soft around the edges to me and lacks any real world power output.
  15. On looks alone, it’s been done before by Shanling with the CDT-300 in 2004 ...is this the first time the French have copied the Chinese instead of the other way around??😝
