Jolida FX Glass Tube DAC

It appears the Pop Pulse uses C-Media's CM108 for the USB interface which is comparably spec'd as the PCM2702.

I also traded emails with a dealer in California who was very responsive and actually e-mailed me back and said the new Jolida DAC was going to be available and was I still interested. After a number of back and forth emails he offered me a very nice price shipped and the deal was done. He emailed me back after receiving my payment and said that Jolida was goinguses the same TI USB chip as my Pop Pulse

I would really like to know how your Jolida DAC turned out after repairs. The one I received is bad as well, signal to noise ratio is terrible, as is the customer service from Jolida and AudioForce.
Horrible experience. -

You either missed the answer to your question as it was posted in the very first post or you are just trying to stir the pot.I emailed Michale Alan and got a call from his tech the next day and he told me to try this and that. Still sounded like **** and the output was very low. Jesse stopped by one night and we both came to the conclusion that something was wrong with it and Jesse also dropped off some Ei tubes for me to try. After Jesse left I emailed Michael Alan and said the DAC sounded like an AM radio. I asked for a RTV number to send it back for a new one and wanted the FedEx paid by them. He replied that everything they send out is tested but if I sent it back they would look at it and replace or repair it, and if there was something wrong with it they would refund my shipping. Three business days after I shipped the unit back I got an E-mail from Michael Alan that said "You were right" it had a loose wire we repaired it and it sounds fine and it will ship out today. I picked it up the next day at a FedEx store and brought it home to give it another try. It sounded much better but not quite what I was hoping for. Michael Alan said to leave it on for a week or two and it does not have to have music playing through it. So after swapping the Ei tubes and the Stock tubes in and out with the stock tubes sounding better than the ( zero hour ) Ei's initially and then after about a week and a half of burn in time it sounds pretty good.
I'm Jesse, I know the details and can say that the service was excellent.

Mine works great but have read a number of the same issues that were discussed here.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

Mine is still working just fine. Brandon is coming over tonight to roll some tubes through it to see what sounds the best in my system.
I will say that I was promised reimbursement for my shipment cost and to my knowledge I have not seen the reimbursement from Jolida. They may have sent it to the wrong address because they shipped the unit to a FedEx retail store.
I understand from Brandon who was/is looking in to getting one that there is already a minor upgrade from Jolida, but that is all I know.

Good news there MLS! These new units are pretty good and very convenient. I would've considered one myself if I had more stored on a HD. I'm currently breaking in a J. Music Van CDP (24/192K) instead--because of this. Not bad even with the Chinese tubes in it...?
Last year I heard a direct comparison between the new Music Van CDP (4 tube unit) with separate R transformers, etc. and the DAC unit. The DAC unit was very 'close' but you could still hear the superiority of the more expensive CDP on Redbook CDs.
Enjoy! Didn't realize Doro had one...he had mentioned seeing a Demo of the unit at a trade show last spring?

Not the case, this has been a painful journey. I ordered the DAC 1 month ago today. Just this afternoon I received an email from Michael Allen stating he is sending the replacement DAC next week.
I am pleased to hear that several of you are pleased with the unit. Look like Jolida is going to take care of the defective unit afterall.

Understood. However, I did receive a call from Audioforce who ordered the unit for you. He said that you still wanted the unit. We can send the new unit out early in the week. Please advise. MA -
Update, Over the last 2 days I have recieved several emails from Jolida to resolve the problems I have had with this DAC.
Jolida has offered to refund or replace the DAC including all shipping charges, AudioForce however is still insisting on a 20% restocking fee on a defective product. This gets me thinking that my customer service issues may heen been AudioForce the whole time.

I would love to, but I chose to go the refund route, and instead of the Jolida I am going with the Cambridge DAC Magic.
The Jolida may be a fine unit, and I appreciate Michael Allen of Jolida stepping in and taking care of business, but I still cant get over the specs listed on the Jolida for the glass FX tube DAC.

How does that look like amp specs?If life had more tubes it would be a lot smoother.

First, I have never seen an "ultralinear class A/B" DAC, makes no sense to run a twin tube DAC push pull, when a single tube running "class A" would have enough gain to drive most amplifiers. Running twin tubes "class A" would however offer excellent gain and improved separation, and reduced crosstalk, which I am sure was the design goal.
Second, I have never seen a DAC measured output 1 watt at 8 ohms, especally when the max output is 2 volts. Also refer to the JD-502, the specs are identical to this DAC.
Signal to noise ration is 85db, exactly the same s/n as their JD 502B
Now look at the:
JD-100 CD player s/n >102db
Their tube preamp s/n > 100db
The JD-9A Phono stage s/n > 100db
I think the specs on this DAC are mistake, I am sure this DAC is far better than the rated specs.

Glass Tube DAC update. Although Michael Allen has been very helpful, he has no control of what his vendors do. 2 weeks ago I returned the DAC to Jolida and still no refund.
I would use caution buying anything from Seller - AudioForce on Audiogon, point of sale serive is good, however is all excuses when it comes time for a refund.
In one of his emails to me he complained he couldn't afford a refund because his car is in the shop.
Nice service Rick.

Don't understand what your spec problem is. The specs for the Jolida 502 are fairly standard for a 'tube' amp? Tube amps have seemingly lower noise and hum than an SS amp but you don't really hear that--in fact it adds to the more analog, warm, tube sound.
That should be taken into consideration whenever comparing any piece of tube equipment to its SS counter part. I have a CDP that has a S/N of over 120db and a Jolida that is a mere 102db. Guess which sounds 'better'? The 102db Jolida--the 'tube' player! Specs are useful but they don't fully describe you what you will 'hear'.

102db is absolutely acceptable for a CD player, preamp or a DAC. 85db however is much too high for audiphile DAC be it Tube Solid state or hybrid. As I stated earlier, I am sure the spec is a misprint.Don't understand what your spec problem is. The specs for the Jolida 502 are fairly standard for a 'tube' amp?

I have a Jolida 502b amplifier and love it. The DAC however is not my cup of tea.

Great news, today paypal interveined and granted my refund.
Following the refund, I received an detailed email from Audioforce expressing his displeasure.
