I have searched the web and can not find any information on U.S. versus European voltages changing which fuse to use. Another fuse that has good reviews is the German made HiFi-Tuning fuse. That maybe easier to purchase in Norway. They cost the same. I would buy a slow blow 4 amp- size small.
I received the Isoclean fuse yesterday. I bought the 3 amp fuse, but I would buy a 4 amp slo blow (it takes the small size) next time . When I took the original fuse out it was a 4 amp fuse. How does it sound? It is a major improvement in sound. There is better clarity of sound- less smearing, better sound stage placement and darker background. I think this is a required upgrade to maximize the Zana Deux sound. Good listening to fellow Zd users. David Pritchard
Dirrerent names but are they the same tube and do they sound the same? Now that is the tough question I can not answer. But it is neat to know that Mazda(often said to be French-esp Fr. army surplus) is Adzam spelled backwards(a Phillips brand). Mullard tube company was bought by Phillips just arter WW1(not WW2). My Valvo was made at the Hamburg, Germany plant. You pay a big premium for the Mullard name. I have not heard it. The only review I have read of the Mullard was...
I have had my PS Audio Power Plant Premier for One week now. First it runs cool NO heat problems. My unit has a newer fan unit. I have not heard the fan come on yet. If you buy one new and register it at PS Audio it has a three year warranty. I bought mine at Audio Video Logic- approved internet dealer. Price was $1599.00. I think this is a good audio investment. It makes the Zana Deux amp sound even better than before. JP, I think this unit would improve that California...
I had never noticed that the Zana Deux had a fuse. I ordered an Isoclean 3 amp slo- blow fuse from VH Audio today. It will be interesting to see if it changes the sound. It is a UL approved fuse-some audio fuses are not. I took the cover off the transformer. That is one big chunk of metal. I wonder if lining the transformer box with ERS paper would do anything? Where's Patrick for his next vibration experiment. I also ordered a set of Herbie's Isocup isolation units to try...
My first interconnects were the Audioquest King Cobra and they are nice, a warm balanced sound. My current cable is the Audioquest Colorado. A copper cable with better definition than the Cobra but no harshness. It made my system forget it's digital. I think it is worth the price when bought used at AudioGon. Good listening David Pritchard
I bought my Valvos from a Hong Kong dealer on E-Bay. I have never seen them for sale by the regular U.S. dealers. Interesting to hear they have some microphonics (I have not tried mine yet). The tube I have been listening to is the Fivre (Italian). It has microphonics when you tap the amp body. This sound is like the ring when tapping Waterford crystal glass. Good listening to all current and future Zd owners. David Pritchard
Great report and thanks guys for the information. One question- what 6SL7GT driver tube was in the Zana Deux. Changing that tube changes the sound of the Zana Deux greatly. I am currently using the unusual Fivre(Italian tube) and it assigns each instrument on the soundstage an exact location. Any listening with my other favorite the Brimar? Thank you again for all the informative information. David Pritchard
I love the Zana Deux #17. My original cables (interconnects) to the Marantz SA-11 SaCd player were the Audioquest King Cobras. I have since tried the My Audio Company Palladium's-improved detail, better bass. These sell on Audiogon for $181.00 via the auction site. I now have tried a used pair of Audioquest Colorado 72v. I was immediately impressed with the precise location of each instrument's location in the soundstage. Both these cables have improved the quality of...
AS I write, I am listening to music through the Audioquest Colorado cables. It certainly is more open and clear than the Audioquest King Cobra it replaced. Another excellant cable is the MAC (My Audio Company) paladium cables. Paladium is in the platinum family of metals. They sell on the Audiogon auction site for approx. $179.00 +shipping. My system is horn speakers and a Jadis tube amp and the Zana Deux headphone amp. The Colorado's go for about $400.00 at the Audiogon...
