>>> You mention 6 tubes, the Joilida uses 2 (12AX7). Can't see how it could be very close?Perhaps Jolida discovered the truth about tube sound and found they could use op-amps in place of most of the tubes and only use a couple of tubes to provide the requisite distortion to produce the tube sound.
Just an educated guess!

reluctance to appreciate what is possible with so-called ancient technology until first hand exposure, e.g. tubes, conical stylus cartridges, etc.No biggie! Mind you there are lost souls that can't even recognize good performance, their biases so resolute they are incapable. Those types can be fustrating, but that's not something open minded folk like you and I need be overly worried about!; truthfully there was a time when I had my doubts about you in this regard, now I know better.
Jolida has discovered something but they still make their best products using all tube circuitry. Their discovery is in this case "less is more" but it is not quite as it may seem or as you have suggested. It is simply about cost. Jolida has two goals, one being to faithfully reproduce the musical event in your home (not necessarily the recording but the actual event, a distinction that they are happy to point out); two being the most affordable product to do so. They may not hit a home run with every product they swing at but they have a good batting average.
The whole point of the JD9 is to build a unit that sounds very nice and that is quite affordable. Also one that fits into their system well. Their tube amplifiers are pure tube integrated amps with line level only inputs for the most part. The JD9 is very solidly built and is large enough to be used as a base for these amplifiers even with one of the heavy muthas such as a JD302B or JD502B resting atop. That gives them the required phono input with a separate power supply and substantial shielding (you can read about that in another post) without having the sound get too tubey as vinyl is already quite warm in many systems. Of course using an opamp design makes the cost much lower and packs quite a bit of function and reliability into a small space. I can't argue with them in this regard as I also favor SS phono designs as the critical first stage of gain. What they then choose to do is to warm-up the sound with a tube buffer that really makes the less expensive systems sound a lot bigger than they would otherwise have any right to.
So Jolida's big discovery is realizing what people want and being able to deliver it. That doen't make them the best in a crowded field but it does give them the edge in their market segment and it makes their customers very happy Buddahs indeed.

Ah yes; "Ridiculous stupidity:""Perhaps Jolida discovered the truth about tube sound and found they could use op-amps in place of most of the tubes and only use a couple of tubes to provide the requisite distortion to produce the tube sound."
My whole system is a POS compared to everyone else's. But I sure am enjoying all the distorted sound coming from my POS speakers. It's a good thing I bought that expensive POS integrated amplifier too. We all know that integrateds suck. And that POS cartridge really should be taken off and melted down. It's so obviously shitty. And how stupid could I have been to buy such a poser turntable. It's not worthy of being called a turntable. What a POS tonearm and motor. I can't believe that such a hacker system could even produce sound let alone be recognizable as music. Man, I cannot believe how much money I've wasted on all this worthless stereo gear. I'm such an idiot.With a big smile on my face every time I sit down to listen to it all. Peace be with you.
You should update your system components in the user profile section to reflect your full-on crappy tastes! Jolida specifically makes gear to be fun to listen to and affordable, not to impress the graph readers or the Jones' ultra-fi crowd.

That is really funny. Funnier even than "wooden tonearms that hang from a string". Wow. -stark
