Preamp Deal of the Century

Any body has a hum/buz (come from high, mid, and low)on Syrah when playing linestage?

Your help would be appreciated.

Stiltskin,

The SRA iso bases are not cheap. $600 for each base for the Cortese. The improvement in sound that I heard was greater than any NOS tubes I have used and I don't have to worry about the iso bases becoming microphonic or going bad. Between Tung Sol round plates and 350B's you could easily spend as much as the iso bases cost. Keep in mind that the base I am experimenting with is not even made for the Cortese! Kevin custom builds each base for the piece of equipment it will be used with. He has a huge data base which tells him the dimensions, weight , and distribution of weight for components.

On music that was not dynamic, the iso base did not exaggerate, but it made the music very fluid. The music flowed and was very relaxing. I could have listened all night with no fatigue. On music that was dynamic, the "slam" factor was staggering! Notes seemed to trail off forever. Attack and decay of notes was more noticeable. I could play music at higher listening levels, and yet the sound never got hard. I guess this was because the iso base was doing a better job of isolating the tubes for vibration. Also keep in mind that my equipment rack sets on a concrete slab floor covered with wall to wall carpet. I would have thought that alone would have aided in isolating vibration. I would think the effects would be even greater on a suspended floor.

Slowhand, You have a good ear. How many hits has this posting got since you started it? ....I'm at a point with my system where some proper isolation should kick it up a notch or two.You and most here know what a thrill it is to discover yet another whole new level of performance that was hidden in your system.My first real eye/ear opener was taking care of the a.c.acouple of years ago.The next HUGE leap were cables.... The only platforms that I have tried under my amps and pre. that worked pretty good were Symposiums top line... Alot of money for some aluminum and foam. More in fact then SRAs platforms. Cello what are your impressions SRAs products? Thank You

Hi Houstonreef. Sounds like your having a bit of a time with your syrah. Is it it a 60 cycle hum or is it a buzz that seems to piggy back the signal? Do you get it on the phono stage as well?

No, i play only linestage. Any idea?
