I likewise don't cotton to Art Dudley’s use of Altec Lansing Valencia speakers to audition other components. He is, I'm sure, aware that to do so would be found questionable by some, but is, as always, secure in his decision to do so regardless.
The Jadis JA200Mk2 review---or slam!
In the current issue of Stereophile, Jason Victor Serinus reviews the new Jadis JA200Mk2....or should I say SLAMS the amp!!
Since I am new to the Jadis family, I thought I would bring up a few interesting thoughts on this review. The first is that I am totally understanding why an amp that uses Ten(10) KT150’s per side would probably not be a great solution at all!!!! Why, well JVS brought up the reason...although he did minimize the impact; the amount of heat this beast gives off is crazy! Space heater in disguise. What’s odd is how JVS also points to his Pass amps as giving off a ton of heat. ?? Anyhow, we then learn that the review was conducted using JVS DAC as the source...and direct into the amps....who does this??? Why on earth would anyone use a DAC to drive a large tube mono block for a magazine review!! No preamp was used. All of the photos of the amp show it using the KT120 tubes...all. There is mention of what the amp was designed with...the KT150’s, but there is some questions to what tubes were actually in the amp under review. Then to go on, the amp was apparently strapped for the 1ohm load....????? JVS doesn’t check these things!...and then states that the amp is not really that great in the bass reproduction. Huh, why would he think that a tube amp that is strapped to the 1ohm setting would produce prodigious bass with his hard to drive Wilson Alexia’s!!! Can we say classical "mismatch" here.
JA’s follow up measurements, while interesting as usual, are IMO also a little odd, what is the base line that he is using to determine accuracy??? Another tube amp...a ss amp, a hybrid design of some sort...his ears, someone else’s ears???
While I purposely did not consider the new Jadis JA 200Mk2 amp for my system, due to the immense heat output...and probable impact on reliability due to this factor ( IME, electronics seem to have a much longer life if heat is not that much of a factor!!! ( Am i one of the few that perhaps understands this??) Plus, i don’t need any space heaters in S.Calif.) I would think that a follow-up review ( preferably by a more experienced reviewer) would be in order....one who can correctly match-up this amp to their ancillary gear.
Anyone else have an opinion of the Jadis JA200Mk2 review in the current issue of Stereophile?
