End of the World Music System




Franz Hinterlehner and his pal Emanuel came from Austria, last weekend... puffing and sweating, but also laughing and having good time, we worked for several hours... thanking Franz's skill and knowledge and friendship and Emanuel's patience and skill, Gotorama is finally completed, folks... a fully bloom reality.

I'm in tears (of joy)... using the someway user unfriendly, yet supremely effective, transparent and... why not, perfect, I dare, TacT RCS 2.2 XP... well, now Gotorama uses Thomas Mayer crossover for Goto's three upper ways and TacT's 2.2 crossovering feature: Franz and myself choose the cool 10th order (yes, it's 60 db/octave) slope between GOTO SG 570 and S-150 horn and Elodis' TGE bass horn and THE RESULT IS SIMPLY, PLAINLY SAID STUNNING... the Mayer's crossover uses as a (not so cheap:-)) "buffer" the Mayer's 801A line-stage preamp, while the WE 437/Tango EQ 600 LCR phono stage goes straight to one of TacT's analog inputs.

TacT is also used as a 192Khz DAC... maybe I could also squeeze a nice coffee from it:-)))!

The sound is, on the best of the nine pre-sets saved and stored in the RCS, superb, right, airy and extremely dynamic, speedy as the light, low-end is clean and natural, unboomy as it can be... and I'm lacking words to describe how such a system is able to sound virtually everything, from a solo acoustic guitar harmonics to Taiko japanese BIG drums and large orchestra or organ at 120 db SPL.

I reached Hakata!

My goal...

My vision...

That is one sexy setup, but where is your reel to reel deck?

Telefunken M15 is on left side and Revox G36 at righe, Stellavox SP7 and Nagra IV-S are in their aluminium flight cases, as mike and AMI48 Stellavox' mixer;-)
Studer B67... is on doctor bench!
'til I'll be not able to use my Leitz' Super Angulon 21mm 3,4 lens, again, the pixes in my Blog will be (someway) average and uncomplete, audio-porn-wise;-)
Best,

Hi, Stefano,

I read your comment about the 60dB/oct crossover and I’m trying to figure out why the SG570, loaded with 75cm diameter horn, sounds so good with such a steep filter. Is it because the S150 horn is running with practically no overloading due to the absence of lower frequency content? I’m interested to know your opinion about that… At what frequency is the crossover point?

Best regards,
Peter Haralanov

Hi Peter... yes, that's PROBABLY the point... I USE ONLY THREE OF Thomas' (Mayer) crossover (transformers coupled and TVC gains) 1st order... crossovers points are 250/1200/7500... sure the S150/SG570 combo gets the cleanest signal and no overload or stress from frequencies below 250 or bass horn blurring mid low S150...
Thanks for yr. interest in Gotorama's
Best,
Stefano
