Preamp Deal of the Century

Cello. While I do not use any of the symposium products,I second your recommendation on their effectiveness.They are terrific with tubed based gear. I have heard the effect first hand in a friends room isolating his magnificent sounding Klimo tube preamp and companion Kent mono amps. Their effect is his rig was not subtle. We have both been promoting the resonance control theory with tubed based equipment for many years. He has spent as much or more on his room than his equipment[read very expensive]and his rig is one of the finest if not "the" finest I have ever heard.The system is vinyl based only and his table is set up out of the room.Every piece of electronics is isolated with symposium pruducts.The noise floor is almost non existant.Music in his room is always magnificent experience.I am still dying to hear my Syrah in his system for comparison.

Eccletique,

I had great success with the Symposium Rollerblocks but not with their Stands (tried the Ultra Symposium and Svelte) under any of my equipment. My best results came from Silent Running Audio custom made stands followed by Zoethecus Z-Slabs used in combination with the Stands.

A good friend also had excellent results by placing Roller Blocks under his TT (Linn) after hearing what they did in my system.

If any of you decide to experiment with the Symposium Roller blocks, make sure you get your hands on some grade 3 Tungsten Carbide Balls. They are a huge improvement over the old stock chromium or the grade 25 Tungsten Carbide Balls. "Double Stacking" works even better.
.

I use Symposium Rollerblock Jrs underneath my SupraTek also. I picked up my grade 3 tungsten carbide balls from mcmaster carr. I forget the price but it was less that half of what Symposium wanted to charge. One of the benefits I noticed with the rollerblocks was an increase in variation of instrumental tones, the opposite of a coloration which would tend to make music more homogenized.

Well gentlemen I am a proponent of Sistrum technology..It is everywhere in my system. In side components as well as outside. Under my subs under my Dunlavy's, under my Dunlavy external crossovers. I have an Sp6 rack and 2 Sp101's, one under each of my amps that are built around Sistrum technology..The acoustic space ship and screen box combo that I described earlier are mounted to the ceiling with Sistrum technology. I have measured a 2 db increase of efficiency using these products..No down side, all the audiophile adjectives apply. Bwhite I would try a Sistrum Sp1 platform under your preamp with the apcd-2 discs between the downward facing points and the equipment shelf. You may also need the Sistrum Sp001 under the outboard power supply. These devices I feel are a major contributor of resolving power and major factor in the reproduction of the 21 ft soundstage I hear and see on several recordings played back on my system.They ain't no darn reflections neither!..

Hi all, I hate to de-bunk this tweak fest you are having, but it's my humble opinion that significant equipment changes or even just trying out alternative audio technology yields much greater improvements than poking around in the dark with tweaks!

As a humourous but true example, I once tried Yamamura Millenium 6000 power cable (@ $400USA) on my Bel Canto DAC-1 and convinced myself over an evening of listening that it was the best thing since sliced bread. Only to wake up the next morning and upon trying my standard power cord, finding that the sound had not changed much at all??

You see, my standard cable for the DAC-1 is a thin bit of zip cord with an in-line switch taken from the rear end of a child's Teddy Bear night lamp (the DAC-1 does not have on ON-OFF switch and this cable allows me to switch it off at will). All I can say is that it must have been a magic Teddy because the cable coming out of it's arse/ass did wonders for my system and more than kept up with the fancy Yamamura power cable!

Tom & others, my advice is:

1. Get a Supratek preamp, they are relatively cheap and get you connected to the music better than any tweak you may have tried.

2. Try Electrostatic loudspeakers like the Quad ESL-57/63 or for that matter ribbons like Apogee Stages or the like. Planar/dipole sound can be the most realistic experience.

3. Try Horn loudspeakers, they can be revelatory.

4. If you must have cone speakers, try and get one with the most expensive drivers and most inert box. Drivers such as Raven Ribbon tweeters; Accuton Ceramics; Cabasse honeycomb foam (21NDC); Eton; Beryllium drivers are excellent and more truthful than all others.

5. Everyone should have a S.E.T 300B/2A3 valve experience at least once in their lives!

6. Bel Canto EVO digital amplifiers and 24bit/96/192kHz DACs are wonderful devices - period!

7. Get at least a Koetsu Rosewood cartridge (or better), a good cartridge makes a greater improvement to any turntable than any arm or deck upgrade/tweak you might make.

In my experience, all of the above changes in equipment yield significantly superior results than tweaky things.

For what it's worth ...

Regards,

Steve M.

PS: Before you flame me, I'm not a total heretic and do use Solid Tech supports under my cdp and other 'feel good' products in my system like the rest of you.
