Hello,
I'm new to this forum, but I've been reading it for a while.
I'm from France, and I'm also the happy owner of an Euforia from Feliks Audio.
I've been practicing tube rolling as well, and I've recently acquired a set of 8 NOS CV1052 coated ST shaped to a french seller who wanted to get rid of all his stock of tubes.
So I have an extra spare set of 4 of these tubes, if one of you is interested (can't post any image for now due to new account restriction).
I'm far from the 100h burn-in some of you here recommend with those tubes, and although it is not the best combo to me yet (after many trials, WE421A, TS5998, RCA5692, KenradVT231, TelefunkenEL12-Spez... I really prefer the Sylvania 6SN7-GTB + Tung-Sol 6080WA combo on the Euforia, slightly superior to me to the WE421A+RCA5692 for a much more reasonable price), it actually sounds very promising regarding the wideness of the sound-stage (but basses are extremely lean and dynamics are still a bit shy).
Cheers,
Erwan.
Hi Erwan....welcome...and glad to hear you're another "happy owner" of an Euforia...an extremely good amp IMHO!!
You have some very good tubes there to spoil her with...and I'm sure a good few folks would be scratching their heads somewhat that you rate the fairly humble Sylvania combo over WE421A etc.!
However, that's a prime example of everyone's tastes being different, along with accompanying gear lol. And all that's important in this hobby is what pleases your ears and brain...and as I've stressed many times before, the most important thing is to
trust your ears!!
Re. the coated ST CV1052s you have, your early findings are precisely what the rest of us have found...so please persevere a good while longer yet (100 hrs plus) - your patience will most surely be rewarded. Bass
will develop, as will perceived
dynamics and greater frequency
range. But I must point out something here that is sometimes not fully appreciated - ie. there is a great difference between bass
quantity and
quality. If too much of the former is presented, it can often result in loss of
detail and
precision...along with masking many of the more subtle frequencies higher up the scale. It can sometimes take quite a long time to really notice and appreciate this...it took me a
good long while!!
And again with
dynamics, greater separation and better placement of instruments and voice can sometimes
appear less dynamic at first, simply because of there being less 'compression', and a wider soundstage. This is most certainly the case with these particular tubes...more so than any others I have ever tried. And a somewhat uncanny result of this is the sudden appearance of notes that were never before heard in certain pieces of very familiar music - a trait noticed by others, as well as myself.
So please give these tubes much longer burn-in yet, and I hope you too may notice these aspects I have mentioned...plus others!
Re. the sale of your excess tubes, without (I hope!) casting any aspersions on your genuine sincerity/honesty, I suspect many folks might like to have the protection of ebay and PayPal, for example, in such purchases...especially as anyone new to head-fi is not allowed to post items in the 'for sale' classifieds until a member for 30 days, and with at least 15 posts under the belt.
But notwithstanding, I do hope you manage to find a buyer very soon...I myself have a good supply at the moment, but may well be in the market for some more if I can't afford the new flagship 2A3 amp. Hopefully, however, someone else will be able to enjoy the special qualities of these tubes, given their scarcity lol!
Whatever, I wish you all the best Erwan...and GOOD LUCK! Not to mention continued enjoyment of your Euforia....Sante! (Please excuse the lack of acute accent!
).
