Jm I did not listen to them side by and you did buy my vac. The SE is much better and certainly worth the extra cash outlay in my opinion.

VAC 160iSE integrated with NOLA speakers
Just to mention as a further update, that I now find that double damping all tubes in the VAC 160iSE - i.e., preamp, input, output sections - works better than single damping. That is I am now using two of Herbie's HAL-O III dampers on each tube in the VAC. Results are just better - more of the same good stuff. |
agriculturist OP76 posts04-15-2016 11:33pmFWIW as an update I went back to using the stock VAC fuse from the SR Red fuse and now find myself actually liking those best. I know another VAC owner prefer the stock fuse in his 300.1a and audiophile fuse in Ren MK3 pre. Trust your ear! |
As an update from me, I have upgraded to the 160iSE from the 160i. The most noticeable difference for me was the black background. The 160i sounded like a tube amp, with some tube noise residue, the 160iSE is dead silent. The midrange is very similar, but the SE version has a tad more resolution in the bass and highs. I am using a Audio Horizon Platinum Reference fuse at the moment. I may have to go back and try the stock fuse again. |
Glad to hear that you like the SE John. I still love the sound of mine for sure. Recently I cleaned out all my power and signal cable connectors with Deoxit, then cleaned with 99% alcohol, and finally put some Furutech nano liquid on the signal cable connectors. Every thing sounds cleaner and more lively now. |
Have ~25 hours on my VAC SigMKIIa pre upgraded to SE and hearing similar improvements described from 160i to 160iSE. Blacker background, lower noise, improved transparency, organic, timbre, musicality ... a totally different preamp and for the cost of upgrade, HIGHLY recommended! Their were minor circuit changes removing a pair of 12au7 ... according to Kevin Hayes, major change is using statement level Lundahl signal transformers. I assume 160iSE is also using statement level transformers? I was talking to Kevin and he said 200 IQ can also roll KT120 and KT150. He hasn't roll KT120 but KT88 beats KT150 in factory and dealer demos. I wonder if 160iSE can also roll KT120 and KT150? Two interesting videos. 200 IQ will trip before blowing a fuse if output tube fails. Now great tube sound with SS low maintenance? Interview with Kevin Hayes on 200 IQ VAC 200 IQ in action |
KngHifi, yes, I believe the transformers in the 160iSE are the same as in the Statement gear, so probably the Lundahl statement level ones. Your 200IQ sounds like it must be great, perhaps better than my integrated I suppose. As I understood it, an advantage of the integrated is the direct coupling of the tubes to the transformers (?) - that is no use of capacitors. But I am no expert in these matters so I am not sure if I am describing this properly. No, the KT120 and KT150s cannot be used in the 160iSE from what Kevin and Brent told me. I have seen good benefits from using Stillpoints - LPIs above as weights on the chassis and ultra aluminums below in damping chassis resonance. I imagine this is one area that VAC probably had to make some compromises, at least relative to the Statement gear, given costs and available chassis space. I am going to try a couple of HRS DPX damping plates on top of the Transformer casings in the next week. I have the amp sitting on top of a SR Tranquility base which is very helpful too. |
JMCGrogan2: I can vouch for the Furutech Nano Liquid. Don't know anything about the Stabilant treatment you used. I got the best impact from cleaning and treating my speaker posts which were dirty and the speaker cables, as well as all digital cable contacts between MacMini, USB converter and DAC. Where the cables/component connectors were newer I got less benefit, and where they were older and more muck and oxidation had collected I got correspondingly more benefit. The DeOxit on all IC and PC connectors was a big plus for sound initially. And later on I cleaned all the IC and speaker connectors again and applied the Nano liquid, and then I got another big bump up in sound. As I have learned, after cleaning with DeOxit, you must clean the muck off the connectors with 99% isopropyl alcohol. I actually even cleaned some easy to reach male AC receptacles and USB receptacles in various components. |
