Hello All,
In a short 6 months (since Nov last year), I have transformed from a person with no hobby - into an infinity and carver fan. I received much help from the AK community - with answers to my many questions (often so basic & naively embarrassing) about audio. I am still learning - but I enjoy every bit of my experience.
Speakers (from left to right): RS IIa, RS IIb, RS IIb, RS 2.5, Column 2, and Kappa 6.1 (photo - not arranged for listening).
Amplifiers: 2 tfm-45, 2 tfm-55, tfm-42, m-4.0t, m-1.5t, marantz 240
Preamp: B&K avp3090, carver c-1 (blown up), carver c-11 (blown up)
Source: Marantz dv7100, denon dcd 1560, Technics sl-1700 mk2 (coming soon)
As others have concluded, the IIb's are the best in that lot - but the watkins woofer sounds sweet and more wholesome to me. Wonder why they did not use it in the IIb's.
Most memorable experience was early February when I hooked up an m-1.5t (recently arrived from the post-office) to my system and it blew up (with a literal big bang that knocked off a fuse in my electrical box) - taking the c-1 to early demise with it. Sparks came off from that 1.5t but no burnt smell.
In the process, I have also learned how to dis-assemble and fix emim. I had two emims with ribbons starting to separate from the base. I built a jig (as suggested) and had no problem taking it off and putting it back. I used scotch tape to secure the ribbons back to the base. I also had an emim with resistance at ~8 ohm - caused by a slight damage to the strip near one terminal and damaged connectors. I applied the rear window defroster repair kit, soldered new wire in, and it solved the problem, bringing back the resistance to 3.4 ohm.
I am refoaming the woofers of the RS IIa - and I am planning to use this set to mod following what others did. I know nothing about electronics, so this will be a slow and long journey.
Weakest link is my preamp - I would like to go tube (AR SP-8 or SP-10) - or DIY tube preamp. Need to wait until I finally finish my house, hopefully by this fall. I know my limit - even with an understanding wife.
I never before realize that source can make a big difference. I thought all CDPs are the same, until I got the denon 1560, which blew the marantz dv7100 off the water. I am trying vinyl soon.
I actually felt guilty having that many infinity speakers but I got such a pleasure looking at and hearing these vintages. Such a refresher listening to them after a long day at the office.
