    The Opamp thread

    It almost seems, especially on Head-Fi, that one person's "bright" is another's "transparent"...same with bass response. I did not notice this opamp sounding too bright, too brittle, too distorted in the treble region whether using my SR225e's, He-400i's, or really any other set I tried with...

    The Opamp thread

    OK, I inserted this little opamp today and have let it play now for 8 hours or so.... It is not a downgrade from the Burson V5i it may be a slight bit "mellower", but that's more of a fleeting impression... More later if I get time to do critical tests.

    Monolith by Monoprice Tube Headphone Amplifier with ESS Sabre DAC (29511)

    The 6N5P/6080/6AS7 tube is not a rectifier tube, it is the output tube, like used in in the Darkvoice 336SE...it is a dual triode that kind of approximates 2-2A3 tubes in one tube, but are not directly heated...it has cathodes for electron emission. 6080 tubes are sometimes used in voltage...

    First thing that comes to mind is that solder is not glue.

    I would like to try something like that on the system, but the room is medium sized and damped, the few watts out of a single 6V6 type tube just wouldn't be enough to push the Spendor D-7s to a reasonable volume....maybe the Reference 3As he has, but the CAT amps, or the Pass XA250's are a...

    It's not my system, let's make that perfectly clear! I'm retired and live off of Social Security, there's no way I can afford something like that...even contemplating the price of the Jupiter capacitors mentioned in this thread is out of my budget...but, I do set-up and evaluate systems for...

    More bass? I just listened to Cryogenic Encounters by Liquid Stranger...I don't see the need for any more force in the bass than that...the well recorded high res FLACs, DSF, and WAV files stored on my computers are shown pretty darn well, the one area I am trying to improve is the "tinkly"...

    I restored that 1962 TR4 from a basket case in the late seventies...I even drove it to a local transportation museum and it earned me a spot as their restoration manager...biggest mistake I made was selling that car, my 1967 390GT Mustang fastback, and my 1976 KZ-900...ahh well, the adventures...

    Little Dot I+ Tube Rolling

    I have two V5i's that aren't good....after playing for a while in the LD 1+ they start distorting, like within 15 minutes to an hour....they wouldn't even work at all in a CMOY type amp I built that has run just about every dual opamp I can get my hands on....I got a second set of the V5i's from...

    Burson Supreme Sound Audio V5-OPA-D,V5-OPA-S Review

    I did!  Yesterday via PayPal.   They were great to work with and are dispatching me another one via FedEx Express.   I can't wait to hear this opamp.

    Burson Supreme Sound Audio V5-OPA-D,V5-OPA-S Review

    Has anyone had any delivery problems from Burson?   I ask because I ordered a V5i to use in my Little Dot amp back on November 30th, my PayPal account was debited, and I still haven't seen it in my mailbox two months later....   There was a tracking number that only showed that the Hong Kong...

    Has anybody seen this comfort mod kit for Grado headphones?

      OK, here's a shot of the back:     I don't recall what they are going to be priced at retail, but they are still in the "tire kicking" stage...

    Has anybody seen this comfort mod kit for Grado headphones?

    This is a prototype kit that came into my part-time job a week or two ago, so naturally I had to grab a set of Grado SR-80's and this kit to bring home and see what the kit did for them:     The kit comes with two adapters that allow you to use AKG style pads in place of the stock Grado...
