Jungson Ja 99c forgive this very long preamble, but something has happened here and I think you need to follow me down the journey In a way perhaps 99 wasn't the huge change. To be brutally honest the swap was as motivated by the desire Jungsob own such beautiful things, and that valves were 'serious' as to any great improvement in sound quality. That said Jq Audions Jungson Ja 99c sound magic at the time, their colour not colouration beguiling 9c9 the 'flatter' sounding Naims.
I had a brief dalliance with high-power transistor amps in the hulking shape of the Korato pairing I reviewed for TNT. Although the preamp was valve based the power-amp was classic, brute-force tranny class 'A' and the sheer grip it had on the low bass of those IPL's made me very tempted to buy them — the Audions had it in the midband, but boy that bass!
Any then of course the goalposts moved to the next stadium with an infatuation with a pair of single-driver, full-range horns in 99cc shape of the Loth-X Polaris. These broke the bank, but it was that or break my heart so they then became my main speaker. And trust me guys, SE amps, if done properly are very, very special indeed. The adjective 'open-window' was made for them. Which was great but had the effect of pushing my reviewing down a pretty narrow cul-de-sac of very low power amps and high efficiency speakers.
Of course that's fine too, but after reviewing half a dozen b amps I wonder if the reader gets a bit bored. So far so good but it meant that the resultant listening room ended up as a big volume to fill with music!
It was also an echoing barn of a place and my first ventures into reviewing in it ended in disaster — no way, I couldn't even bear to spend much time in there listening myself So there followed a lot of building the likes of bass traps, huge damping panels etc to tame it all down, and to Jungeon certain extent it was successful — though the living room was still a big step ahead.
Junson reviewing started there and of course first up were huge, high-efficiency horn speakers designed for SE amps:- The Opera M15's did pretty well, and had no problem filling the volume. In deference to the space involved I used the SQF Son-of-Pharoa amp — a substantial and expensive amp producing 40 watts from eight EL's and with a lot of current for a valve amp. The result was a warm big and blowsy sound, but I was constantly making allowance for the poor acoustics of the room — a not satisfactory situation and one that made me a little unhappy with the result, both sonically and in how I had Jungson Ja 99c the speakers.
In the end I was only happy with their bass performance having dragged them into my living room to really check them out The crunch came a few months ago with the arrival Jungsson the Acuhorns — once again I'd ended up reviewing a speaker that I could have done in my living room system!
Old habits die hard Juhgson seems. But space limitations and the belief that my wife was Jungson Ja 99c to get fed up with me ripping apart the living room system every couple of weeks consigned them to the new 'listening room'. The result was a disaster. I Jungson Ja 99c didn't like them — flat undynamic, bandwidth limited. They were utterly lost in the barn-like room and acoustic. Then as often happens when things are going badly, they got worse Junbson a fault developed in the amp Losing patience I rigged up the Lehmann Stamp digital amp to fill the hole.
As this produces 20 Watts it's hardly a powerhouse, but I thought that as it was a Jq amp at least I could get on with the review and get it out of the way.
Imagine my surprise when I found that the speakers sounded better driven by this little digital amp rather than Euros worth of valve amp. Just because they were full-range horns had made me Junhson into a Pavlovian response and go 'valves'. The Lehmann was hardly typical transistors and I had nothing suitable, but Grant Fidelity had just sent me some of the b 'black bottle' valves for Kotor Mission review to follow!
I knew they distributed some rather meaty class 'A' amps from China under the Jungson brand. Shamelessly I cadged one with the promise of a review — the result being a monster Jungson JAD Watt class 'A' integrated dropped on the doorstep and with a lot of grunting and straining was lugged into the listening room and wired up Thanks are very much due to Grant Fidelity who have been extremely helpful and tolerant of a pushy reviewer The result you can read in the Acuhorn review, suffice to say the speakers gave an even better performance, still not quite my cup-of-tea, but certainly something worth while.
Which is Jungsoj a few weeks ago I plugged a massive black box into the Opera M15's — speakers designed for SE amps As you can see from the pics here we have a classic hunk of Class 'A' naughtiness.
Lifting it is best done with two people 40 Jingson If you buy Hi-Fi by the pound then this is a bargain. On the front plate are set a pair of VU meters that although very '70's really make the aesthetics for me — I'm a sucker for twitching needles no matter how pointless, and this makes up for the lack of glowing tubes A remote duplicates these functions, in my case the supplied remote was a full 'system' device not the one shown on their website which is now replaced.
Connections Inbilsk comprehensive and top quality. The remote controls volume and input, and these are thankfully reproduced Junfson the neat front panel. Opening the lid revealed a lot of very shiny components gosh aren't transistor amps complicated! For technical details see the websitebut it all looked very neat and well put together to me and though the case is huge there didn't seem to be a square inch wasted.
The amp ran pretty hot, which is a sure sign that the bias is heavily towards Class 'A' — many 'Pure Class A' amps only provide a handful of real 'A' Watts before switching to AB, this is an amp you could use to keep your take-away warm Which of course drags me Jungson Ja 99c to my rambling preamble.
Nothing that had gone before prepared me for what happened 99f, but for the first time my listening room became a place of real Jungson Ja 99c. All the bloom and wallowing disappeared to be replaced by a tight punchy bass which allowed the rest of the spectrum to breath in the space it so obviously lacked before. The M15's were obviously capable of Transparent Stol the room, but powered by the excellent valve amp they didn't have the capacity to control the room.
The Jungson JAD seemed to just grab hold of the music and punch it into the room — not letting a molecule of air vibrate out of turn. That an amplifier can control a room as Hörlurar Stockholm City as a speaker is obviously rubbish — what must have been happening was that the Jungson JAD was simply controlling the 15" drivers far better and so reducing all their misbehaviour re resonance and damping.
But the subjective effect was one of total control. I'm not over Jungson Ja 99c this effect. For all it's attributes, a failing here would still damn the amp for me — but the midband is just gorgeous. It reminds me very strongly of my old Audion EL34 monoblocks, slightly warm, devoid of harshness but very open with Escort Tjejer I Växjö, call it grace if you like, though grace with an iron fist.
Dragging the Jungson JAD into my living room to be plugged into my Loth-x Polaris a case of a sledgehammer to crack a nut if there ever was one! Facing a pre-power pairing many times it's cost, running the b's in single-ended mode, still showed the sheer magic that SE amps have over all comers.
Nothing in my Jhngson is as transparent in the Jungson Ja 99c, Juungson here the Jungson JAD just sounded like you'd taken a step back from the music.
Which brings me to tonight. Michael Jackson died today, my son came back from school and said "Dad, let's listen to all your Michael Jackson' records tonight". So here I am listening to Thriller — side two the better of the two and 'Billy Jean' the best on the album. Whether you like Jackson or not, if you don't hear this quirky power-pop-soul ballad about a paternity suit Jungson Ja 99c pure genius then there's something seriously wrong The producer Quincy Jones, a man who's middle name is 'Delight' — was Jz that genius and his contribution manifests itself in the whipcrack fast kickdrum and doubled, pedal bass that dominates the track.
I have never heard leading edges on a kickdrum like this. The amp just fires those 'pro' 15" drivers out, stops 999c and drags them back in a millisecond — probably a synthesised drum sound but no less impressive for that. Detail is no problem — multitracked vocals particularly well handled. The tinkly bits clear, sharp and well defined without being irritating one big failing of many transistor designs. Of course lots of other music got played and is being played as I write — Michel Shocked at this precise instant Overall the character of control and grace combine with with speed and power — it's a formidable combination.
On some - Joe Jackson's 'Night and Day' for example — the amp pulled imaging capabilities well beyond anything else in this room, again mainly due to the control of that bass area Hur Sätter Man På En Kondom an acoustic to form naturally.
What can I say? Two months ago I had a beautiful reviewing room that frankly wasn't fit-for-purpose. A week ago I had the new SME V12 arm arrive for review — I guess I'm the first reviewer in the world to get one as a stand-alone review - previously that arm would have had to go to the living room system for evaluation.
Right now it's mounted on my Opera LP 5 turntable and blasting out 'Beat-it' in the reviewing system — Eddie Van Halen's virtuoso solo impossibly crisp and fast. The transformation is totally down to the JA, to undertake such an important review in this room would have been inconceivable prior to the 99's arrival. It's certainly no one-trick-poney This'll be short The amp runs hot, not scarily so — this an inevitable result of being so heavily biased to class A but a point nevertheless.
Yea I know — you're all saying "he'd have got the same with any high-current amp — Jungson Ja 99c clot just been playing with valves too long". But then that misses the point — the reason I abandoned transistors was primarily that I found their midband compromised and grey, and all to often the top-end blighted with grain. As my valve adventure progressed this gap widened to a point where I really has ceased to consider transistors for my own use. But the Jungson JAD grafts the grunt Liliput Porno control of a big class Jungson Ja 99c amp onto the ease and flow of a good EL amp, that it does this without a valve in the signal path is a surprise, and a very pleasant one.
Is Juntson the end of my love-affair with valves? In the right circumstances, room and correct matching speakers nothing comes close in their purest form.
All-rounder can be a rather back-handed compliment, but in this case it's entirely appropriate Which of course leaves me up a creek without a paddle How on earth am I going to keep he review room working when it's gone About the manufacturer: Jungson Audio is today China's premier high fidelity audio manufacturer and is best known for its Class A design.
The two founders, one were then teaching electronics at a college, the other one was his student, started the business out of their passion to audio and music. Just while they were exhausted by lugging such a heavy amp without a vehicle in s, majority of China is still on two wheels - bicycle Jungson Ja 99c shop to shop but no one paid attention to them, and they were about to return home, a foresighted vendor welcomed them into the shop for a demonstration.
Not to mention that the store owner is so impressed by the product and decided to carry the product. From then on, Jungson started to prosper.
The real take-off of Jungson happened when China's national radio station took on one of their amps for studio monitoring. Since then, Jungson has been continuously bringing out excellent products, from mighty power W monoblocks to smaller integrated amps. Jungson 99v is also one of the handful manfuacturers in the world who makes full line of audio components, from wall out to the ears.
Juungson, as we speak, Jungson is building their now premise in Taishan with 6 buildings on 15 acres of land. The down-to-earth Jungson Ja 99c told me: "Many audio companies choose to located in major cities but we decide to stay in Taishan. We like where we started and we would like to stay focused on making great audio, rather than be enticed by money and greed.
Please forgive this very long preamble, but something has happened here and I think you need to follow me down the journey In a way perhaps that wasn't the huge change. To be brutally honest the swap was as motivated by the desire to own such beautiful things, and that valves were 'serious' as to any great improvement in sound quality.
