For me its the first or very early LP's of: Allman Brothers - "Allman Joys" "Idyllwild South" Santana - "Santana" 200 g reissue Emerson Lake and Palmer - "Emerson Lake and Palmer" and, Beethoven - "Piano Concerto No. 4 in G Major" Rudolph Serkin/Ozawa/BSO
i think the Hagerman is crying out for mass, then springs...... like a 1/4 or more plate w holes drilled for tubes, granite base and springs.....
Jim, now on that I agree. But, unlike Mikey stated, you aren’t going to flip it over with IC/phono cables. That was a more than slight and unnecessary exaggeration.
One problem is that the bottom has venting slots, so probably cannot be fully covered. The bottom/base would be a great place to install a heavy plate, or similar. Hey, I have my bag of excess lead weight for the SOTA I could simply tape inside 😉 I do have some DynaMat that I could strategically place inside. That would help reduce vibration within the chassis, but wouldn’t add mass as in actual substantial weight.
But really, the Trumpet is pretty incredible ‘as-is’. That said, tube rolling, a possible external power supply, (I tried one I had after consulting Jim, but took it ‘off’), and yes, the possibility of making it more impervious to vibrations (especially with the tubes) seems to make sense, and I’m sure could make it even better than it is, which is pretty darn good to my ears.
As Muveling has noted in a post. The Trumpet has found a place only below his VAC Renaissance, but places it above his Herron VTPH-2A, Rogue Ares, and Sonic Frontiers Phono 1 SE.
If any of you guys pick up the new Lucinda Williams Runnin' Down a Dream T.P. tribute, I'd love to hear your impressions. I wanted to stream it and see if it is worth getting, but doesn't seem to be available on any of the streaming services I have.
i should clarify, compound spring systems with TT, when they exhibit reinforcing fundamental resonance frequencies are bad in an obvious and often woofer puking way. i don’t think you are doing anything wrong Steve to wit your good sonic results.
i based my comments on real world experience w a 6 degree of freedom base miscalculated for TT mass on a minus K system, only a quick hand ( not mine ) on the volume saved the speakers....
Steve - what are you using for shelves ? i need to change mine at the condo
i have also heard the new compound setup and it is stellar, perhaps the best system i have ever heard.. The miscalculation was result of incorrect mass specification from TT mfg, running change , improvements.....ha
Brian - high praise indeed for the Trumpet - Muveling and i had more than a few conversations when i decided to put the Herron in the audition pile. He unlike another third person voice Herron BOOSTER has credibility because he has actually owned and listened to many phono preamps and many carts. fun and that’s the point.
I opened the Trumpet this morning, and strategically placed some DynaMat I have. Tight confines after the bottom/side plate is installed, so had to be careful. That stuff does not come back off easily. Anyway, tapping on the chassis, no more ‘ping’, but instead a ‘thud’. Will it help? Well, it surely cannot hurt. Not really any good areas to install actual mass with the tolerances between board(s), various components, and the chassis itself without some more major retooling. Jim’s work is neat and tidy inside. Very nicely done.
Yea Jim, as we chatted about this before the purchase, Muveling‘s comments were what focused and narrowed my decision. The fact that he has had several high end phono stages, and I haven’t, meant a lot in making my decision.
And as a constant ‘bargain hunter’, it also checked that box. That said, you guys have gotten me to crack my safe much larger than I normally would/do, and have always given good advice in how and where to do so. For that, I’m indebted, and my enjoyment has been rewarded.
There is a self adhesive vinyl damping material available at www.partsexpress.com that I’ve used successfully in several applications. Probably easier to remove than Dynamat. In fact I’m gonna order more soon.
Thanks Steve, I’ll check that out. DynaMat works great.
I have a significant amount of it inside my CD player. The Pro-Ject I sold had a significant amount of it under its plinth. Jeez, probably used it elsewhere as well. Still have a nice sized sheet left for medium to small uses, even after installing it within the Trumpet.
The above mentioned Vega lp is great. I'm addmittingly a big fan, but while this lp/s aren't THE absolute best for SQ, it just draws you in, constantly wanting to turn up the volume. In doing so, it sounds better and better.
Brian, vibration control, as in vibration drainage from the internal parts of the component and drained out & away from the component. The sonic gains are of articulation and very fine definition that you find in the depth of listening. Vibration drainage greatly helps to maximize what the component has to offer. That's why I offered the Symposium website link. My two cents on the matter... Either way, do have fun.
Last night...
The B-52's 'Mesopotamia' I forgot how good this album is. So much instrumentation going on, a lot of fun. Great SQ.
Golden Earing 'Moontan' Fabulous album, but lousy SQ. What a shame that it has no bass.
Joan Armatrading 'To The Limit' Fabulous album, I love Joan. Now this album has bass!!!
Stomo Yumashta, Steve Winwood, Michael Shrieve 'Go' Winwood is the highlight of this album, for me. This one can take you for a ride to outer space. Great one to end the night on. Drift off to sleep.
George Weldon conducts Elgar - Cockaigne, Overture, Op. 40 / Chanson De Matin And Chanson De Nuit, Op. 15 / Pop And Circumstance Marches, Op. 39 / Serenade For Strings In E Minor, Op. 20. The Royal Philharmonic Orchestra. RCA Victrola 1968
EDIT: Man, this a great recording and engineered so well. I love finding old albums that are so well done. And pretty darn quiet too. I gotta see if this guy has any more LP’s I want. I’ve bought a few now, an always in great shape, an very good recordings too.
Stillpoints offers a vibration control product specifically for circuit boards. When I inquired to Pat at SMC Audio, he said it wasn’t a good value, (I’m paraphrasing)..even though Steve remarked on the Stillpoints page, his positive opinion.
for the adventuresome who are mucking about w speaker crossovers, Wonder Coat conformal coating is what Vandersteen use on the Treo at least to reduce microphonics.... the Quattro and up use more advanced technologies....
Brian - i am going to put some Dynamat in the boat cabin for noise reduction if it proves a bit howly....

DynaMat was pretty much created for the auto industry; for use under hoods, trunks, etc. So pretty impervious to water.
The bad thing about it is trying to remove it. Attempted once, and quickly gave up. So, when you place it, you better not want to move it again. Which is why I might take a look at the other dampening product you mentioned from Parts Express.
DynaMat is excellent for stopping ringing of metal. Great for car doors, floorboards, fire wall, rear quarter panels, etc. (I worked in the car audio industry for 34 years). Not necessarily for home audio products, though. Draining vibration, or, microphonics from within the audio component is more important and delivers better results, sonically. DynaMat or other such materials won't help that. A vibration drainage device/system is more in line to do so. However, if one chooses to dampen the component chassis vibration then maybe try a self adhesive sorbothane sheet. Audioquest sells 6" X 6" X 1/8" sheets and they are inexpensive. Recommended use is, for example, inside the top cover of a CD player.
Michael Percy sells EAR Isodamp SD in various thicknesses. He recommends the SD125 (1/8" thick) for damping metal enclosures. He says it’s the best thing he has found for that use. Economically priced, too. I stuck it inside my Herron Phono stage, EAR Yoshino line stage, and Music Reference power amps (RM-200 Mk.2, RM-9 Mk.2, RM-10 Mk.2) transformer covers. Works fine.
Do ya’ll know about "razoring" Maggies? Maggie maniacs pull up the socks on their speakers, and put DynaMat on all the metal parts of the magnetic-planar drivers and ribbon tweeters. Sounds like a LOT of work ;-) .
