[Cableman]

Thanks and welcome. What speakers? Any analog?

Sorry. It says Audiopax 150s. Thx.

 

[Cableman]

Yes. Audiostone Pythagoras TT and Thales TT with Ecosse Cables rewired tone arm

 

[Cableman]

On

Stunning system!

ongaku was the first amp I heard that came close to the music IMO. only bettered by the Audiopax Model 88 again IMO

Pair of First Watt SIT-1 here, powering TAD TD-2001/ET-704 on top of the coming new sattelite comprising
2 x TAD TM-1201H, TAD TD-4003/JMLC400, TAD TD-2002/JMLC1000, TAD ET703.

Sry, but as I wrote "the coming New sattelites" - these are in the build as we speak, an expansion of the old sattelites comprising FLH with Altec 515-G, TAD TD-4001/ custom made radial horn / TAD ET-703

The New sattelites will also have the Accuphase F25 filter changed to the DF-55, Mid-bass amd midrange channels will both be powered by separate Accuphase A50V amps.

TAD2002/ET-7003 to be xo'ed passively.

46 monoblocks with 417a driver and Interstage transformer.

YL Acoustic horns and EV T-350 tweeter. Jensen 15” woofer in open baffle.

All right then, here is my set:

Preamp Revox B750 MKII -- total revised in 2016
four Amps Revox A740 -- all total revised in 2015
Speaker Tannoy Canterbury SE -- reconed in 2015
Phono Preamp Monk-Audio -- bought new in 2014





well it's vintage, but plays terrific and incredibly good .
connected by bi-amping and bi-wireing - on recommendation of Tannoy

best regards,
Rainer

Nice! A year ago I finally came across a pair of T-350 myself, actually NOS in boxes! Been searching for a decent pair for years..

They sound incredibly smooth and have the advantage of reaching further Down in frequency compared to more traditional horn-loaded tweeters - but you already know that probably!

Now a fixed member of my tweeter Family... found a Picture (not the best quality I'm afraid)

my Geroukis 211 Parallel Set pair.. built to order Kondo Gakuon Replicas.. with Kondo Transformers, 1050 volts plate voltage, 3X 5687 & 2X VT-4-C (GE 211) 60 Watts per channel.. Amazing performance..

Yes, the T-350 is an excellent tweeter. Smooth, detailed, and it blends very well with the YL Acoustic midrange horn. My speakers came with T-35 tweeters and I didn’t like them at all. Its big brother the T-350 is a very different animal.

 

[hieffdesigns]

That's definitely correct. I had a few EV TRXB's in 12" and 15" Versions - and they have the t-35 Incorporated but they cannot be compared to their bigger Brother. The T-350 is also an excellent Companion to many wide band drivers - reasonably comparable sensitivity ( you don't have to dampen the Hell outa them...) and you can xover below the traditional frequency area where the whizzer cones have issues on Your typical 8"

A most versatile and underrated tweeter in today's world of Exotica..

What are you using to attenuate the level of the T-350? L-Pad? Autoformer? Or discrete resistors? My speakers came with L-Pads for the mid and tweet, but I noticed a nice improvement in sound quality when I replaced them with Mills wirewound resistors. Of course, it took some fiddling around to get the right values but once I did I haven't felt any need to adjust them. I also tried a set of Slagle autoformers on the midrange but preferred the Mills resistors.

I agree with you about the low end extension of the T-350. My speakers came with a simple 6db crossover for the tweeter at 10K and the midrange running flat on the high end, i.e. no crossover rolloff. In my case, the midrange was a little smoother when I rolled it off so I now use a 7K second-order crossover on both the midrange and T-350.

I do not use the T-350 at the moment but when I tried them out they where connected to a pair of SIT-1 attenuated via the active filter. Bur for testing passive I would normally use the Fostex R100T and measure until preferred Level, then if I where to keep the tweeter as a permanent installation change to fixed resistors type Duelund CAST.
Please observe these are MY personal observations and preferences and they might not suit everyone's taste or opinion.

Old photo: The Ypsilon phonostage has been replaced by a Tim Evans SR and the Audiopax Amps are now a one off unique version of the Model88 made with some input from me to Audiopax and (bizarrely) named after me.

The Meither has been upgraded to XDS1/Dac2xV2

I understand totally. It's all about individual choices. For example, I have a box full of Duelund resistors and a few CAST capacitors, and they aren't my cup of tea at all. Lots of other people do like them though, so I understand why you would use them.

Here goes my system.

Here is a picture with the new Audiopax Mandolin Ceramik. People here in Brazil are trading speakers like SF Stradivari, WA Sasha, Thiel 3.7 and many others for those.
