Thank you for the hint to the GraphitAudio footers! I‘m using a dedicated platform from Akustik Manufaktur called „The Rock“ which improved the SQ of the TRP IMO with the standard footers, will look for the GraphitAudio ones.
I had an email conversation with Lampizator concerning upgrade...
I ordered as well a Sophia pair to give it a try. One of my GEC KT66 quit after approx. two years now, Fortunately, I‘ve a spare pair . My previous ranking was GEC KT66, Psvane 6CA7, GL KT77. Currently I use the 6CA7 and are pleased with the progress I hear after more hours of operation. I can...
Great gear presented in this thread, I noticed so far. I was a little active in the Lampizator Golden Atlantic TRP thread, so here is my listening room around the Silvercore TB3/1000 SET amps with a Valvet Soulshine 2 MK2 preamp:
I fully agree to your findings, that isolation is an important factor. I did some tests mainly focusing on my tube power amps with Akustik Manufaktur platforms. Picture shows a test platform, I‘m awaiting now the final handcrafted ones in high gloss white, the isolation technique is identical...
Depends on the SQ of the USB output IMO. I did a comparison between an Antipodes EX with direct USB output to the TRP. The SQ was on the same level as an USBridge, the USBridge Sig with a LPS is my current favorite with a Calisto cord. Roon core is on a .Mac Mini, a Bonn N8 serves as a switch.
For clarification: Are you using HQ Player w/o upsampling to DSD or the Roon native player?
I cannot comment on HQ Player, but made the same experience with Roon native player and prefer non-oversampling, even with Audirvana, same result.
Sorry, no progress in tube comparisons, I swapped back to Psvane 274b/GEC KT66, and focus on some listening room tweakings (audiophile circuit breaker, separate power line and racks for my SET amps ;):p).
Will take some time.
excellent decision, I went directly to TRP after having the chance to listen to an A1 in some versions.
For the tubes I started with a standard 5C3S/EL34 combo, upgraded first with a Gold Lion KT77. The recti was exchanged with a RK 5UG4, and luckily I found a pair of NOS GEC KT66...
@Golum Interesting report from Fabio on the Psvane 6CA7 and maybe I give it a chance. I cannot comment on tha Taka recti, for me the combo of ACME 274b with GEC KT66 NOS is still my favorite over Gold Lion KT77 and the KR 5U4G.
I just received the ACME 274b two days ago and ran it with my GEC NOS KT66 and can agree with @Golum clear, detailed, spacious (!!!), airy (!!) compared to the RK5U4G. I listened to the HighRes version of Jazz at the Pawnshop and cross checked with Stevie Ray. The impression after these first...
I‘m unsure where reasonable price ends for you, there is a shop in Germany, who has the tubes on stock and maybe VAT is partly deducted, they ship international:
