| Phono Stage Amp @cinqcepages - Trying to find the gain specs for your phono stage, with no joy thus far. The following review does mention that your M1 has less than the 60dB I brought up and possible problems, with LOMCs (carts of <1 mV output): ... | |
| Phono Stage Amp If your system is capable of providing a satisfying SPL, with your CD/digital sources (typical output: around 2V), but: not with the output of your analog rig; the problem is obviously the lack of voltage from the phono stage. Either se... | |
| Is there a strategy in preamp tube placement? I couldn't agree more, that a tube buyer should be familiar with their seller. BUT: that's seldom the case, with the first-timer or neophyte. "...but there are many among us who don't know what you are talking about when you use terms ... | |
| Is there a strategy in preamp tube placement? btw: Crazy price on that linked, eBay pair of KRs (to me, anyway), BUT, then there’s: https://www.ebay.com/itm/174924762007?hash=item28ba540b97:g:1UYAAOSwfj1hNNVb (PLUS SHIPPING!) That French seller is clearly very proud of his tubes!... | |
| Is there a strategy in preamp tube placement? "These days I’d also be leery of counterfeits of tubes that are now 70 and more years old. The best sounding KRs are the black glass variant. You can’t see what you’re buying." The 1940s, Ken-Rad, VT-231/JAN-CKR/6SN7GT has bottom getterin... | |
| Is there a strategy in preamp tube placement? YEP (Brent charges $5/tube for noise testing)! A vid, describing his testing method, can be found just into the the tube description portion of this page: http://www.audiotubes.com/6sn7.htm ... | |
| Softest, smoothest sounding capacitors you've tried? Much of the, "vintage sound" you're referring to was generated by the carbon composition resistors used, back in the day. There are still a variety of Cornell-Dubilier, Black Cat capacitors available, that seemed a favorite, among many... | |
| Upgrade from Kimber D60 Digital Coax cable If your gear will do AES/EBU; find a Kimber Orchid (not less than 1.5 M). You'll keep it! | |
| Linlai E 6sn7 tubes @ram18 - "Havent felt the bass depth or slam that is often associated with the KRs." Has your system, as it now is configured (talking about components, speakers and room) ever produced the kind of Bass depth and slam, that you are attemp... | |
| Linlai E 6sn7 tubes "Chill out, you’ve got 4 new tubes installed which require break-in. True NOS Ken Rads need 50-60 hours... ’ +1 This is a verbatim quote, from a letter Brent Jessee sends, when... | |
| Linlai E 6sn7 tubes @ram18 - "I have much to learn." Don’t let anyone snow you. We’re all (still) on the same curve! Have fun! | |
| Linlai E 6sn7 tubes After all, this hobby is pretty much about experimenting until you get the right combination of ingredients which sounds right to you. I've always viewed the hobby as an amalgam of science, art and cooking. The first always depends ... | |
| Linlai E 6sn7 tubes @ram18 - Those figures would indicate tube strength/life and the balance between triode sections. Nothing, regarding noise. There are various ways to test for microphonics/noise*. My (personal) favorite procedure simply invol... | |
| Linlai E 6sn7 tubes @ram18 - Those are the ones. The CKR, bottom-gettering and copper rods (at the top), are a dead giveaway. Be very careful about obtaining tubes rigorously tested/guaranteed for low noise, if they're going in a preamp. | |
| Linlai E 6sn7 tubes @lowrider57 - I don’t even remember buying my pair of two hole, t-plate, bottom-gettered, VT-231 Sylvanias, or: ever having listened to them. Must have been when I was going through that 6SN7 comparison from Chimera Labs, and trying ev... |
