How do I create a custom array in powershell?

I am trying to sort out arrays in PS. The problem I am trying to solve is to return a list of replicated VMs and some basic stats.

Having read through a multitude of sites and suggestions the best I could get is the following script:

$myArray = @()

$vms = get-vm | where-object { $_.replicationstate -ne "Disabled" }

foreach ($vm in $vms)
{
    $vmRepl = Get-VMReplication

    $replfreq = (New-TimeSpan -seconds $vmRepl.replicationfrequencysec)
    $lastrepl = $vmRepl.lastreplicationtime
    $nextrepl = $lastrepl + $replfreq
    $secfrom = [math]::Round((New-TimeSpan -start     $vmRepl.lastreplicationtime).TotalSeconds)
    $secto = [math]::Round((New-TimeSpan -end ($vmRepl.lastreplicationtime + $replfreq)).TotalSeconds)

    $obj = New-Object System.Object
    $obj | Add-Member -MemberType NoteProperty -Name Name -Value $vmRepl.Name
    $obj | Add-Member -MemberType NoteProperty -Name ReplicationFrequencySec -Value $vmRepl.replicationfrequencysec
    $obj | Add-Member -MemberType NoteProperty -Name SecondsSinceLastRepl -Value $secfrom
    $obj | Add-Member -MemberType NoteProperty -Name SecondsUntilNextRepl -Value $secto
    $obj | Add-Member -MemberType NoteProperty -Name LastReplication -Value $lastrepl
    $obj | Add-Member -MemberType NoteProperty -Name NextReplication -Value $nextrepl

    $myArray += $obj

}

write-output $myArray | ft -AutoSize

This works when I only have one VM, but when there are multiple ones the output appears within curly braces.

I think I am on the right track finally. I just need someone to help me sort out the remaining piece(s) of the puzzle.

The other weird thing is that the New-TimeSpan stops working with multiple VMs.

Thanks in advance.
