I asked in another thread looking for advice with the Jolida tubes but I decided open a new topic focus on it.
I have the Jolida 502B with Paradigm Monitor 11 speakers, with Xindaq DAC and reader, waiting to upgrade this periferials.
I really like to hear jazz as Joshua Reed, Herbie Hancock, Spyro Gyra, Chick Corea, Yellow Jackets... rock as Everything But The Girl, Depeche Mode, even Metalica or Rammstein... and electronic DJ"S as Armin Van Buuren, Oakenfold, Chicane, Enigma...
At this moment I have a Electro Harmonix salad in the Jolida, last owner legacy.
The sound that I have is very "shinny" or in excess sharp...with a feel of "we need a subwoffer", despite the Paradigme Monitor 11 and the 502B punch. I'm conscious about some room reflection yet but I can't improve it more...family matters :)
In my country Costa Rica, a $45 individual tube will cost around $110 with the custom taxes and shipping costs. So I have to be low profile about it.
I REALLY APPRECCIATE YOUR ADVICE ABOUT IT! I know is difficult but a good tube is a good tube and a poor brand too.
Reading the reviews on tube depot and tubestore on this tubes:
large plate AX7's ?? I read that this get more medium bass and tight bass presence:
- BLACK SABLE Sovtek 12AX7LPS
- SOVTEK 12AX7LPS Preamp Vacuum Tube
- JJ ECC803s / Hi-Performance 12AX7 / tubedepot.com
- Mullard 12AX7 / ECC83 / thetubestore.com
""Microphonics is not an issue despite the larger that average plate structure. The transconductance on my sample was the same as two NOS samples I measured. Not really high gain at all, but a real good noise floor and a nice smooth tone that doesn’t encourage ear fatigue the way some preamps can be."
- 12AT7 / ECC81 Mullard / tubedepot.com
- Mullard 12AT7WA / CV4024 / thetubestore.com
"The NOS Mullard 12AT7WA / CV4024 tube is low noise and long lasting. This 12AT7 tube is a very good choice for hifi preamps, driver stages, and guitar amp reverb circuits. The Mullard 12AT7 is original production from Great Britain."
For the KT88;s
- Sovtek 6550WE / tubedepot.com
"The Sovtek 6550WE has higher gain / output than most others and really has a ballsy sound. Recommended for any bass application and most Hi-Fi amps. This tube has a slight bump in the midrange making it a great choice for lead guitar."
- Sovtek KT88 / thetubestore.com
""The Sovtek KT88 tube has smooth, warm and clear with excellent imaging. The bass (except for the very bottom end) is tight and the high end is crystal clear. The separation of parts and balance is better than any of the 6550 tube types."
- JJ KT88 / thetubestore.com
"The JJ KT88 tube has the best imaging of all the tubes in this category. The bass is unique in that it compresses the very bottom end. This provides incredible bass response without ever losing control. Overall a great KT88 tube for orchestral, opera, and jazz music."
