Amp recommendations for Joseph Audio Perspectives2
@elliottbnewcombjr Thanks for sharing. Do you know if there are wheels options for the JA perspectives? I have isoacoustics GAIA feet to put them on my floors but it would be nice to have wheels installed. I ordered a VAC renaissance 70/70 mk3 to match the vac renaissance mk5 pre for the perspectives2. Will see how it goes. |
I own the DNA-1 Platinum Ultra amplifier and would recommend contacting McCormack and see if they have one around that isn't upgraded. I went that route then had it upgraded twice over time. Easy enough if you are local to SoCal (however, not sure about current situation on pickup/delivery). One thing to note, it has an extremely high gain and should be carefully matched with a preamp. I'm actually in the process of auditioning a passive device that has an adjustable active gain and see how that works in my setup. |
these speakers around 80 lbs each. IMO they are heavy enough for stability on wheels. lift one of these 80 lb bags of concrete mix at home depot, https://www.homedepot.com/p/Quikrete-80-lb-Concrete-Mix-110180/100318511 ....................................3 wheels for speakers. no wobble and more weight/wheel than 4. 80lb speaker: 26 lbs/3 wheels rather than 20 lbs/4 wheels anti-tilt rear corner blocks (slightly shorter than the wheel height) do not touch floor when stationary, but contact floor if speaker starts to tilt during movement. softer wheels for hard floors; harder wheels for carpet 2 front corner wheels, stable left to right 1 rear center wheel, unstable in rear when moving 2 anti-tilt corner blocks in rear ....................................... quickie finds, just to illustrate ideas wood finish, 14 x 14 simply relocate a rear wheel and add two rear anti-tilt corner blocks https://www.wayfair.com/outdoor/pdp/innova-hearth-and-home-square-caddy-innv1246.html perhaps try these, see if you actually benefit from adjusting toe-in. If not, remove them. listen on spikes; listen on 3 wheels, any difference? I seriously doubt it. ......................................... furniture dolly, 11.5 x 22.5 cut to size, make finished wood cover to conceal it https://www.homedepot.com/p/Stalwart-440-lbs-Wheeled-Furniture-Dolly-M550109/302662176 cut to size, reattach wheels, add two anti-tip blocks, then have local woodworker make a cover that simply drops over it, finished wood, laminate, paint, .... .......................................... IF, after preferred placement is found, only adjusting toe-in, never pushing them rearwards, you might think about leaving the factory spikes, put them on a properly sized base plate that can be rotated. .................................... btw, 4 wheels can certainly work, you get a bit less weight per wheel, might not matter, and you simply need to solve any wobble that might occur, not hard, but I have bad back and knees, so I go for 3 wheels. You want the drivers to move, not the speaker, so 3 wheels is definitely preferred. |
