K3cT Posted February 2, 2020 Report Share Posted February 2, 2020 I'm a bit out of the loop with audio lately so please bear with me, is the difference between the new beezar/ecp T4 and DSHA-3 is the tube input stage? Which one is the more ideal pairing with the Utopia? The Focal are amazing and made my previous headphone SR-007 pretty much obsolete but the amps I have at the moment, Beta 22 and Dynahi, seem to be less than an ideal match for them as they're too honest. I could definitely use a softer presentation. Quote Link to comment Share on other sites More sharing options...
dsavitsk Posted February 2, 2020 Author Report Share Posted February 2, 2020 The T4 and the 3F do share similarities in the topology of the output stage, but the implementation is very different. The T4 is high voltage, low current with a step down transformer (and a DC blocking capacitor) while the 3F is high current, low voltage and is DC coupled. (The 3 - as opposed to the 3F - uses an output transformer, but no DC blocking cap.) The T4 has a single ended input with a tube LTP stage for gain and splitting. The 3F has an input transformer for gain and splitting. 3F is generally the better Focal option, but it is for balanced phones only. Quote Link to comment Share on other sites More sharing options...

So the 3F (or 3) should be better if one happened to connect a planar to it? say Impedance in 40's sensitivity 90ish Quote Link to comment Share on other sites More sharing options...
dsavitsk Posted February 3, 2020 Author Report Share Posted February 3, 2020 Probably. We have not found the T4 to be great with most planars. Quote Link to comment Share on other sites More sharing options...

Would you agree that the 3 or 3F is the more flexible amp? Quote Link to comment Share on other sites More sharing options...
purk Posted February 7, 2021 Report Share Posted February 7, 2021 Been listening to the L3 & Ravensweood tonight/early morning and they are such a stunning performer! Any news on the T5? Still kicking myself a bit for letting one of the DHSA-2 prototype go 3 years ago. 2 Quote Link to comment Share on other sites More sharing options...
Sherwood Posted February 10, 2021 Report Share Posted February 10, 2021 I still adore my ECP L2 with my HD800s but my listening has switched entirely to the Raal SR1a. I'm not eager to let the amp go, but if any ECP-curious folks would like to hear one of life's great pleasures, let me know. I'm happy to find a reasonable price for the HC faithful. 1 Quote Link to comment Share on other sites More sharing options...

Circuit boards for the Raal experiment (code named "Bridgeport") have been ordered. I should know more about that in a few weeks. Also, there is some thought to doing a very small run of a 10 year anniversary version of the L2. The basic circuit would remain the same, but there are a few changes that should serve as an upgrade to the original. 9 Quote Link to comment Share on other sites More sharing options...

Indefinitely is way too long but if you're willing to loan it to me for some weeks I'll be extremely glad to pay shipping and other expenses both ways. I'm unsure what's the taxes and import fees between Moldova and EU countries. 1 Quote Link to comment Share on other sites More sharing options...
