From what I've read...the new Trident consoles were getting good reviews, though there probably haven't aren't too many out in the field yet for any long-term, broad perspectives. Keep in mind that they are coming from the same company (PMI) as the Toft...though I think everyone agrees even from the start that the new Trident consoles are of a much higher caliber than the Toft...but also, look at their price too.
AFA the vintage Trident 65...that's the first model that came from that Trident line...sorta the lower-budget version of the big vintage Trident consoles. My London 24 is basically a later version model of what the 65 started. The channel modules are relatively the same, but the group/monitors section on mine is different...it's a 24 channel section and it has a few extra features.
That particular 65 has been up for sale for awhile if I recall....his price is just a little on the high side, considering it has only the 8-channel group/monitor section...so that was probably the earliest/most basic version in that series.
That said...the listing claims it's been fully recapped and re-chipped, improved grounding and better power supplies...which adds up to about $2k worth of improvements.
If I was going to make an offer...I would start at maybe $4k, considering it's been up for sale for awhile, and this appears to be some sort of music store/outlet, and not an individual studio owner...so I'm sure they would like to get it out of there.
Use the fact that the wood framing looks kinda beat up, as leverage for the lower offer...that maybe it wasn't cared for well...etc...etc.
AFA how much better will it be than the Toft...well, I can tell you that my London 24 is dead quiet and sound fantastic....but I did a good portion of the work myself, and the previous owner started the overhaul by doing an absolutely killer job on the grounding and overall power distribution...which goes a long way toward making the board quieter and improving the headroom. Also...mine had the master section modified for improved headroom, along with 4 channels mods, which also adds to the improved sonic quality.
Bottom line...if someone offered me a brand new 32 channel Toft in trade for my London 24...I wouldn't take it.
I can't speak for that 65, not having heard/used it...but it appears that much of it has been overhauled, so there shouldn't be much more it would need to take it to the best-case scenario.
One thing...these vintage Tridents do not have as much routing options as even the
Tascam boards. My 3500 had more options and it took me a little time to adjust to the Trident, but most of that was due to 25 years of using the 3500...I could work it with my eyes closed. Now I've gotten used to the Trident, and it feels as comfortable, and I'm not really missing anything I had with the 3500.
IOW...these are pro consoles capable of providing all the needed functionality...and once overhauled, they can sound quite good.
That 65 is also a smaller footprint that my London 24...which might be right for your space, if you are really considering it.
