Tubes for Jolida Fusion Preamp

Thanks all for the responses. I will check into the suggested suppliers.

As an addendum, I am currently running a Bryston DAC-1 with Audiophileo 2 w/PurePower into the Fusion (Lowrider, I believe you also use the AP/PP converter ) The pre drives a BEL 1001 MK5 which in turn feeds a pair of Esoteric MG10s. My system resides in a tuned dedicated room 12x15x8.5’. I am very happy with the musical experience this system provides. However, as I never owned tube gear I have never had the opportunity to explore the benefits tube rolling provides. Therefore, I think I would like to find a set of tubes that most sonically contrast the Tung-Sol tubes that were supplied with the pre. Looking as much for the learning experience as an upgrade.

Thanks again to all.

I submitted a further response on Friday which has yet not been posted. Yes Lowrider I had mistaken you for another, sorry. Anyway as an update I have decided on the following route:

I have searched the web sites of TCtube, thetubestore, and Brent Jesse and will likely do business with them. The Brent Jesse site was most helpful in describing tube build, nomenclature, and sonics.

Given the possibilities are vast and the price range wide, I have decided that I will call the Jolida preamp person and get his opinion. Barring the result doesn’t influence me otherwise, I am leaning towards purchasing from Brent Jesse a set of GE blackplate triple mica tubes for about $200 a set (all 4 required tubes).

I will update everyone as to purchases and impressions. Thanks again for the advise.

Wolf, can’t believe the gluten free tubes are the fave throughout the Great Plains states.

Wolf, thanks for the followup. Have not yet moved on tube purchase, will soon.

Well, I ordered a set of Mullard tubes. CV 4024 (at7) and CV 4004 (ax7) platinum grade from Upscale Audio. Was looking to warm up the upper mids and lower treble and was advised they would do that. I will get back to everyone after a comparative listening session. It is likely that these will not be the only tubes I purchase, just my 1st foray into tube rolling. Thanks again.

My tubes have arrived. I will keep everyone posted as to my findings once I have installed them.

Well I have installed the new tubes and am quite pleased. After a couple extended listening sessions have concluded that the upper mids and treble are more refined and the imageing has improved.

Just for the education, after I have gotten more familiar with the new sound my plan is to reinstall the original tubes to get a better handle on the differences. After which, I have no doubt the Mullards will remain.

Jeenam, I considered the Gold Lions. May try a set of these one day

Thanks to all!
