Sonic changes of the Level-2 mod: The unit is quieter, the silences are blacker, thus resolving more low level detail, ambience and three dimensionality.
It is much more detailed while also more dynamic. It seems to play louder while keeping that beautiful EL-34 midrange liquidity.
Tonal balance is more eve.from lows to highs in addition to the amazingly liquid midrange of the stock machine.
Imaging is better and more defined while bass is dramatically improved. It has full weight and authority, not flubby "one note" bass. It sounds much more like solid-state in this area

Sonic changes of Mini modification
The modded amp is 60% of our Level-2 mod and will outperform any hi-power integrated that we have heard for under $3,500. It is more harmonically correct than most solid-state amps at any price.

Quieter.... the silences are blacker, thus resolving more low level detail, ambience and three dimensionality.
It is more detailed while also more dynamic. It seems to play louder.
Tonal balance is more even from lows to high .in addition to the amazingly liquid midrange of the stock machine.
Imaging is crisper and more defined while bass is dramatically improved. Better weight and authority, not flubby "one note" bass. Sounds more like solid-state in this area.

With 100 big tube watts and 150 watts at 1KHz, the modified JD-1000RC will drive almost any speaker. It uses less than 5dB of feedback and sounds great with a big 3D soundstage. Compare it to the $4000 amps from CJ, ARC and others that only put out 45-50 watts and you will understand its value at double the power and half their price.

New Jolida JD-700 modification

The JD-700 is a quality CD/DVD player with a 2-channel tube output stage. The stock unit is the best sounding, reasonably priced DVD player that we know of for playing Redbook CDs. The unit also offers balanced outputs for fully balanced systems. Once modified, it is much better than the stock JD-100 CD Player and a wonderful Redbook player that also plays video as well as DVD/Audio. The basic mods are developed for this unit's front L and R channel single-ended outputs.

New Jolida JD-707 modification

The JD-707 is a new 40wpc Jolida integrated amp that is sonically extremely close to the low-powered sub-10-watt SET amps. Our mod is a major upgrade and allows users to get the gorgeous midrange and sonic reality that these micro-power amps offer but have enough power to drive most real-world speakers.

Jolida JD-707 Level-1 mod - $1590 ($650 retrofit) -

Hi Walter,
Just a quick note on the Jolida.First impressions are very good! That is after only an hour warm-up, with middle-of-the-road interconnects and stock power cord. Got some smooth-plate NOS Telefunken's on the way, just out of curiosity. Next is a better PC and ICs. Looks like good old 16 bit/44.1kHz is finally living up to its promise.
Best regards,
John S.
Walter,
I just wanted to drop you a line after I've listened to the Jolida JD-100 for several days. Right out of the box, the Jolida beat the Rega Planet 2000 hands-down. I mean literally. I hooked both units up to my VTL 5.5 and loaded the same CD in each and fired them both up. I began switching between the Rega and the Jolida and there was no comparison. The Jolida opened the room up, the highs were more detailed and the bass was full and engaging. The midrange was beautiful.
My next step was to pit the Jolida up against my Linn Sondek LP12. Whenever I have compared the Linn turntable with a CD player in the past, there was always a distinct difference between the analog presentation and the CD. The analog would always deliver more information and detail, with significant improvement in the bass. When I began the same A/B test between the Linn and the Jolida, I was amazed at how similar the Jolida's presentation was to the LP12. I am finding it difficult to distinguish one from the other except for the clicks and pops of analog.
Thanks again for this recommendation and I look forward to seeing how the Jolida can really perform after it breaks in.

Hi Walter,
I received the unit on Thursday. Went out of town until this morning. After spending the day with it, wow!.What can I say, it is heads above the A-3 and the other players I have had ( Meridian 506.24, 508.2, Classe .5 etc.).What bass, smooth. I am running an MFA tube amp, a Classe DR-6 and a pair of speakers I made, ( a single 10" Hartley 220HS woofer in a 3.5 cu. ft. vented box 1 1/2" thick, lined with sheet lead, no coil, just a solen cap on a Danish-made Hyquphon 3/4" dome). I get chills up my spine when listening. Lots of air around all the instruments, not just the soloists. The player does not sound like a CD player, very analog. Thanks for all your help. You know your stuff and provide the best service! I will recommend the player to all that will listen.
Thanks again, I know we will do business again.
Jim

New JD300B no-compromise mod

Our design goal was to take this $2,300 amp and make it as good as the competition that sells for up to $8000. Price for the mod was not the issue, performance the only goal. We use only the very best of parts and the end result is an amazing remote-controlled 300B integrated amp that you have to hear to believe. Quoting from its first review, we learn:

"... Surveying the scene of 300B amps I know about, the Jolida JD300B Level-2 is clearly fabulous value considering its build quality, functionality and extremely low self-noise. Its resolving power should be well suited for the kind of financially matched front-ends that are likely to become its mates. The very non-finnicky, wide-angle remote worked flawlessly. Its inclusion predicts far more open doors for this affable 300B integrated than were this feature missing. It has, after all and rightly so, become nearly de rigeur in the real world. Listeners who sympathize with my expressed sonic biases are advised to experiment with intrinsically fast and neutral -- or even slightly lean -- cables. They'll balance against the amp's obvious body and density. Those listeners who adore 300Bs for what they do with such particular panache will love the Jolida as is. Because of its numerous inputs, you can build a rather complex system around it...

In the $2.5 - 3.5K range, the options for integrateds are larger than ever, both for solid-state and tubes. But as soon as you narrow down the tube choices to 300Bs, things get rather skinny. Demand remote control to boot and they become outright barren. If this budget range is you as is a lustful Jones for this 'king of triodes', today's custom-modified Jolida -- or perhaps even its stock version -- finally give you something to play with. And once you have played with it, you might call it exactly what you had been looking for all along..."
